AI Primer for Marketers Part 9: Preparing For the Future
The most innovative marketers routinely pick up new things, try them out, and succeed or fail. Why are marketers struggling so much to adapt to artificial intelligence and machine learning? In this series, we’ll explore machine learning and artificial intelligence to build a foundation for understanding the field – and how it applies to marketing.

Preparing Your Career for an AI Future

As AI and machine learning become more powerful, we will inevitably see changes in the workforce. The most rote and repetitive information jobs we’ll automate, as just as robots automated those jobs in factories and manufacturing. So, what should we be doing to ensure our careers are long and fruitful in a landscape where machines can learn a sizable portion of what we do every day?

We focus on three areas of growth:
- Watching the watchers
- Multi-disciplinary thinking
- Algorithmic thinking
Watching the Watchers

One of the key critical tasks we will need to perform as AI evolves is supervision. For good or ill, AI code is still largely written by humans today and will be for the near term future. That means our fears, our biases, and our agendas will sneak into code. One career or duty which will be prominent in the coming years is a human checking and validating the output of AI software.

For example, Pro Publica wrote a great piece recently about a police algorithm that attempted, using data and machine learning, to identify which criminals were likely to re-offend, to commit a future offense. Their software did a generally terrible job, about 20% accuracy. Flipping a coin would have been far more accurate. However, their software also classified African-Americans as five times more likely to re-offend, which was also incorrect.

We will need humans to consistently and vigorously fact-check the AI software until we’re certain it’s free of our biases and incorrect assumptions. Otherwise, we might end up with an entire AI generation of Tays, AI software that speaks to our worst impulses.

How many bad marketing assumptions might you accidentally build into your machine learning marketing platform?

Multi-Disciplinary Thinking

Most AI software today is purpose-built, meaning that it has a dedicated function, such as image recognition or natural language processing. As a result, the training of these artificial intelligence tools is limited to its function; the tools can’t see how we will use them outside of the narrow context for which they’ve been designed.

Thus, anyone who is a strong multi-disciplinary thinker will have an advantage when it comes to working with AI. Someone who can take an algorithm, an API, or an AI and use it for multiple, different purposes, or who can chain together different tools to achieve an entirely unexpected outcome, will have significant career prospects until AI software becomes fully sentient and self-aware.

For example, imagine the marketer who takes a list of customers and uses machine learning to identify the best customers with heavy statistical analysis. The multi-disciplinary thinker would then determine ways to use that output for other inputs, from website optimization to social media ads to marketing creative collateral.

Algorithmic Thinking

While machines and software are making the creation and generation of code easier than ever, the ability to think and design software from a conceptual perspective isn’t getting any easier. Today, a designer can pick up drag and drop software and create ready-to-use AI-powered applications in minutes or hours instead of weeks and months. However, without an understanding of how to think about software design, such applications are likely to be duds.

People who think algorithmically, who create designs that are efficient and effective, will continue to be in very high demand. While AI software can learn from past patterns, the act of pure creativity – even in software development – is still not something we can outsource to the machines. The best thinking and designers have a long, prosperous road ahead of them – especially if they have domain expertise. A marketer who can also design algorithms for an AI to use will be a priceless asset and a significant strategic advantage for a company.

Here’s an example. If you’ve not heard of it, MIT makes a great piece of software called Scratch, a kids’ programming language. Instead of writing code, kids drag and drop design components together, from control loops to variables to sensors.

Without needing to write code, kids create software architecture, and some incredibly elaborate software. They don’t need to worry about a misplaced semi-colon or an incorrect indent – they focus all their efforts on design and architecture of code, rather than syntax.

Now, compare the above with IBM Node-RED:

The similarities are striking; however, instead of creating video games, IBM Node-RED allows non-programmers to work directly with services like IBM Watson’s various APIs. Someone who grew up learning Scratch could easily transfer their software architecture skills to Node-RED and be productive as an AI developer almost immediately because they learned to think algorithmically.

Conclusion

The future of AI in marketing – or many other fields – is bright, but so are our prospects if we’re willing to adapt and work with the machines, rather than oppose them. We can, as IBM CEO Ginny Rometty says, transform AI into augmented intelligence, making us as capable and powerful humans as possible, with our machines doing the heavy lifting.

AI Primer for Marketers Part 8: AI-Powered Distribution
The most innovative marketers routinely pick up new things, try them out, and succeed or fail. Why are marketers struggling so much to adapt to artificial intelligence and machine learning? In this series, we’ll explore machine learning and artificial intelligence to build a foundation for understanding the field – and how it applies to marketing.

AI Applications in Marketing: AI-Powered Content Distribution

Distributing our marketing is both easier and harder than ever. Easier, because there are more opportunities than ever, more channels for us to find relevant audiences. Harder, because there are more distractions than ever, more channels for our audience ignore or avoid us on. In our smartphones, millions of more entertaining choices exist than our content, if our content is dull. Machine learning and artificial intelligence help us to overcome some of these obstacles in three different ways:
- Programmatic advertising
- Influencer identification
- Identifying highly complex audience data patterns
Programmatic Advertising

Programmatic advertising is machine learning-powered advertising. Gone are the days of setting up manual bidding and placements in ads; today, programmatic advertising does much of the heavy lifting in terms of setting up tests to determine which ads should go to which audiences.

With programmatic advertising, we provide our ad creatives and parameters for a campaign, and let the system do the rest. A programmatic advertising system will run hundreds or thousands of different tests to determine the best possible performance for our ads, find and bid on thousands of different ad slots and inventory opportunities, and run our ads for us.

Who uses programmatic advertising? Everyone from AdWords/Google Display Network users to the most sophisticated demand-side platforms uses programmatic advertising. If you’ve ever run a campaign in AdWords/Google Display Network in which you selected “Smart bidding” as the bidding choice, you’ve used programmatic advertising.

Identification of Influencers

Influencer marketing is all the rage in digital marketing, largely because many companies haven’t figured out how drastically the ad landscape has changed. Today, influencers account for 7.7% of marketing resource allocation, according to IDC. Yet an astonishingly large number of companies still do influencer identification using decade-old methods, finding influencers with nothing more than Google, qualifying them by follower counts.

Modern influencer marketing uses machine learning techniques such as graphing databases and sophisticated mathematics to find influencers. Algorithms such as Betweenness Centrality, Eigenvector Centrality, and Degree Closeness help us to map out social networks much more intelligently, then determine what kind of influencer we’re after.

Here’s an example using Social Media Marketing World’s 2017 conversations:

We might consider, for example, quality of connection when identifying influencers. We may not want the person who is connected to everyone; we may want a person connected to our specific audience profile. I’d rather work with an influencer who’s influential with CMOs, for example, than consumers.

Much of the best influencer identification software, like AI software in general, is available for free, such as Apache Tinkerpop, Apache Giraph, and other open-source tools. With effective, modern influencer identification, we improve our content distribution efforts.

Patterns in Complex Audience Data

Finally, content distribution often fails because we don’t know our audiences well enough. We make broad assumptions using older tools like personas, or worse, we just assume everyone wants the same thing. Many patterns in data are invisible to the naked eye, to the average human mind, especially when we consider many different data dimensions.

Combining advanced statistical tests like random forests with simulations like multi-armed bandits gives us the ability to forecast and test many different assumptions about our audiences to prove or disprove what will resonate with them. For example, suppose in our random forest exploration we discover that LinkedIn is our best channel for generating desirable outcomes.

We might then take the known statistics and analytics from LinkedIn and feed that data as a starting point to a multi-armed bandit.

We’d test a series of probabilities – such as type of post (image, text, video) – to the software and make a simulation of likely outcomes. Based on our testing, we’d move forward with the outcome that’s most likely to generate the results we want.

Next: Conclusion

To wrap up this series, we’ll discuss some of the things you can do to prepare in your personal career for an AI and machine learning future. Stay tuned!

AI Primer for Marketers Part 7: AI-Powered Analytics

The most innovative marketers routinely pick up new things, try them out, and succeed or fail. Why are marketers struggling so much to adapt to artificial intelligence and machine learning? In this series, we’ll explore machine learning and artificial intelligence to build a foundation for understanding the field – and how it applies to marketing.

AI Applications in Marketing: AI-Powered Conversation

Analytics is one of the most enduring areas of study in marketing. We’ve been working with data and analytics since the beginning of digital marketing. Those folks who have been in the marketing field for some time remember the days of downloading server logs and processing them with spreadsheets and other software to calculate even the simplest of metrics like website visitors. So much has changed since those early days, but one thing remains the same for the most part: Analytics looks at what happened.

The promise of artificial intelligence and machine learning is to simplify and accelerate our analysis of what happened. Right now, analytics is still a very manual task. Even with great applications like Google Analytics™, we still must go hunting for answers rather than have answers presented to us. That’s not necessarily a bad thing – it is, after all, job security. However, one of the key critical problems with marketing analytics today is that there’s too much data regurgitation and not enough insight, not enough useful information to take action on.

Spotting Trends and Digesting Data

With machine learning, we can digest and extract information out of the massive quantity of marketing data much faster. We can also detect trends and outliers much faster, then develop an understanding of what caused those trends in a data.

For example, suppose we have a large amount of data about our website. We have social sharing data, page views, time on page, bounce rate, keyword searches, all sorts of information about the performance of our content. This is a typical situation for a marketer to be in: we have a surplus of data but a lack of useful insight.

Using an ensemble machine learning technique like a random forest, we can digest down all this data to identify the most important variables which lead to our desired outcome. Looking over a thousand pages in my website and more than two dozen variables, what matters? What gets me more social sharing, for example?

When it comes to social sharing, here’s an example of using a random forest to identify the variables that matter the most.

This test of variable important says that Stumbleupon and LinkedIn contribute significantly to the sharing of my website content, followed by Ttwitter. If I were spending all my time trying to activate my content on Facebook, I would naturally have poorer results then if I had used these other networks. Digesting down those thousand pages and dozens of variables would have taken hours or days by hand; using a random forest took literally seconds.

Predictive Analytics

The promise of machine learning and artificial intelligence extends beyond faster analytics, however. In the hierarchy of analytics, once we understand what happened – descriptive and diagnostic analytics – we must evolve our understanding to predictive and prescriptive analytics.

How would our marketing change if we knew what was going to happen? How would it change if we even had a semblance of an idea of what was going to happen? We would likely change our plans significantly. We would allocate resources much more efficiently. We would focus our efforts on the times when our business is needed us most, from periods when we are likely to reap disproportionate rewards for efforts to mitigating weak spots when our businesses would suffer.

Predictive analytics is not a pipe dream or a far-off vision of the future. We use it today in our work. For example, using predictive analytics modeling software, I routinely take Google Analytics™ data and project it forward 12 months. I do the same with social media data, email marketing data, virtually any kind of normal, time-based data series. By projecting forward 12 months, I can identify likely strong and weak spots in the weeks and months ahead.

Armed with this knowledge, I can then build campaigns to double down on strong periods and mitigate weak periods. Predictive analytics lets me budget more carefully and thoughtfully comma and helps me make a case for increasing resources at key time periods, rather than asking for blanket budget and resource increases (which are unlikely to be approved in today’s business climate).

The best part is that much of the software needed to do these different types of machine learning is available for free. The major advancements in machine learning technology all stem from academia. Researchers and developers publish their code online for free under open source licenses; as long as you have the developmental and technical capabilities to implement their code, you can have these tools today for low or no-cost.

AI Primer for Marketers Part 6: AI-Powered Conversation
The most innovative marketers routinely pick up new things, try them out, and succeed or fail. Why are marketers struggling so much to adapt to artificial intelligence and machine learning? In this series, we’ll explore machine learning and artificial intelligence to build a foundation for understanding the field – and how it applies to marketing.

AI Applications in Marketing: AI-Powered Conversation

One of the greatest challenges we have faced in marketing in years past is true customization and personalization. Early attempts to do customization with software often left customers feeling unsatisfied at best. We’ve all received that email from a fellow marketer that starts with "Hello %FirstName%" and had a chuckle and a bit of vicarious embarrassment.

The reason the promise of personalization has not panned out is because we treat people in clusters and groups that we can mentally manage. Our marketing capabilities simply cannot create true personalization for thousands or millions of people. Could you imagine even trying to build a website with thousands of variations for every possible customer? It’s an insurmountable task.

As a result, we pulled back from personalization. We started creating artificial constructs like customer personas to cluster types of customers together. However, we know that personas are lies. There is no Sally Soccer Mom, no Tony Technologist. These aggregated people don’t exist; every person is a unique individual. Creating marketing based on these gross generalizations has led to unimpactful campaigns, causing customers to feel like abstract afterthoughts rather than valued individuals.

Talking 1:1 to Millions of Customers

All that has changed with the advent of artificial intelligence and conversations powered by machines. Unlike humans, machines create new instances of themselves for every customer. Every time our machines talk to a customer via a chatbot, for example, they are speaking in a true one-to-one interactions, individual machine instance to individual human.

In one example, IBM has developed and published a Watson tone analyzer for customer service:

The Watson tone analyzer service lets us know the emotional state of a customer when an issue is escalated from automated machine service to human interaction. We know how the customer feels, what issues they have, and we’re able to respond accurately to the customer’s needs. We integrate technology like this into our websites, our messaging apps, our chatbots and soon, even our call centers.

Beyond customer service, however, we are entering the age of conversational advertising.

Customers Talking to Ads

Here’s an example of an advertisement in which we, the audience, have a conversation with an ad. We tell the ad our favorite ingredient or dish:

…and IBM Watson creates a unique recipe just for us based on our favorite ingredient:

Naturally, the created recipe uses the advertiser’s product. What an innovation: the ability for us to not only have 1:1 interactions with our customers at scale, but to provide them unique content that is only for them. What better way to help someone feel valued for their uniqueness than to make something just for them.

Building AI Integrations

You might be saying, “well, that’s great if you’re IBM or can afford IBM’s services, but what about the rest of us?”. The good news is that these technologies can be licensed from any of the major tech giants. Amazon AWS, Google Cloud, IBM Bluemix, Microsoft Cognitive, and many other tech companies offer developers the ability to use their AI platforms on a pay-as-you-go basis, starting at fees as low as tenths of a penny per use.

Here’s an example of a service I built. I wrote a URL scanner that tells me how many times a piece of content has been shared, and on what social networks it was shared on most.

That’s useful stuff, but I was able to use IBM Watson through IBM’s developer portal to add Watson’s language analysis capabilities to my software. Now, for any given URL, I not only know what was shared, but I can run statistical analysis to determine if particular tones, sentiment, or emotions engender more sharing. (If you’re interested in using this technology, I offer it through my employer, SHIFT Communications)

Even individual programmers or developers have access to artificial intelligence tools for true mass personalization and conversation today. If you haven’t already tried tools from the major vendors, get started.

AI Primer for Marketers Part 5: AI-Powered Content Creation
The most innovative marketers routinely pick up new things, try them out, and succeed or fail. Why are marketers struggling so much to adapt to artificial intelligence and machine learning? In this series, we’ll explore machine learning and artificial intelligence to build a foundation for understanding the field – and how it applies to marketing.

AI Applications in Marketing: Content Creation

In the last post, we reviewed the different types of artificial intelligence and machine learning technologies, and how they fit together in a landscape of development. However, everything we have discussed up to this point has been largely theoretical. Let’s change perspectives and look at practical applications of many of these technologies in use today.

While artificial intelligence technologies have not reached a point where they can create content autonomously, they are exceptionally useful in helping us determine what content to create. The first of these technologies is called topic modeling, which uses natural language processing and natural language understanding. Topic modeling helps us digest enormous amounts of content to understand what the key topics are within a body of text.

For example, suppose we are trying to understand how people talk about our company. We could skim news articles or social media updates about our company, but once we reach a certain volume, there’s simply no way for us to keep up. No one human could read all of the articles or conversations about Ford Motor cCompany or IBM. We would struggle to even read a day’s worth of conversations. Yet, if we want to create content that is relevant to our audiences, we must have an understanding of what it is they want to hear about.

Topic Modeling

Enter topic modeling. We can feed large quantities of text to machine learning software to extract out the most relevant topics to the conversation. Topic modeling has its origins in simple mathematics; beginning programmers often make software which delivers a raw number of word frequencies, the number of times a word appears within a piece of text. While frequency is important, so is what is known as saliency, or the relevance of a particular word or phrase to the body of text as a whole. For example, I use coffee shops in many of my marketing examples. The word coffee may appear frequently within my text, but it is not necessarily salient to the topic of digital marketing.

Topic modeling allows us to determine not only which topics are most frequent, but also most salient, so that we have a better understanding of what contents are create that uses not only popular, high-frequency terms, but also those most relevant to our audiences.

Let’s look at a small-scale example of topic modeling in action. Suppose I want to understand the key topics that make up the top search results for a given search term. We know from previous revelations that Google uses topic modeling as part of understanding the intent of a searcher. What if we were to use topic modeling to effectively reverse-engineer Google’s own algorithm and better understand what contents create in order to rank well?

For this example, we’ll be very meta and look at the search term content marketing:

Using topic modeling, we’d extract the contents of every top search result on page 1 – news articles, OneBox summaries, and regular web pages – into a single, large corpus of text. We’d then create a lexicon of known specialty terms so that our machine learning software has a solid starting point to know what words and phrases are jargon. With that lexicon in place, we’d run the corpus of text through a popular topic modeling application such as NLTK for Python or MALLET for Java, then map it with a network mapping tool:

With this topic model, we now know what our content about content marketing should be about. From here, we’d build our web pages, news stories, and social media content using this map and its contents to stand a better chance of ranking well for the content marketing search term.

A second example of machine learning and AI in content production today is clustering and classification. We teach machine learning software to recognize, for example, top performing content such as social media posts, blog posts, images, etc. and build a corpus of knowledge about what things work best. Based on this training library, we then assess content we create to identify how similar our content is to “winning content” and make adjustments accordingly.

AI Primer for Marketers Part 4: The AI Landscape
The most innovative marketers routinely pick up new things, try them out, and succeed or fail. Why are marketers struggling so much to adapt to artificial intelligence and machine learning? In this series, we’ll explore machine learning and artificial intelligence to build a foundation for understanding the field – and how it applies to marketing.

The AI Landscape

In the last post, we looked at the basics of machine learning and the two types that exist. Within each type, there are dozens if not hundreds of different techniques for machine learning. Each of them is based on a statistical or mathematical principle that makes them effective in certain circumstances. One of the most difficult challenges in machine learning in artificial intelligence is knowing which techniques to use and when.

Because each technique has its own inherent strengths and weaknesses, it takes time and experience to know whether a given technique fits the problem at hand. However, the most advanced forms of machine learning and artificial intelligence don’t restrict themselves to just one type or technique. The most advanced implementations of artificial intelligence use many techniques together.

Artificial Neural Networks

Imagine an individual technique in machine learning as a single piece of a toy train set, a single piece of rail. That’s not very much fun, but it’s better than nothing. Now imagine a box full of toy train track pieces. That’s much more fun; we can build all sorts of interesting set ups for our trains to ride on.

Each individual piece leads to the next piece, which leads to the next piece and so on. Every now and then, we might have a loop where a train can go back over a certain part of the track. The eventual outcome is a complete system which takes the toy train from its origin to its destination.

A neural network is the connection of different machine learning techniques together in a linear path, like the toy train tracks pieced together. We tie together different techniques in a reasonably linear path applying different forms of statistics and mathematics, until we achieve the result we want.

Artificial neural networks get their name from the fact that they resemble the way the human brain works, with many different pieces talking to each other and pathways from one piece to the next.

What’s the practical application of this kind of technology in marketing? Artificial neural networks are best suited for highly unstructured and highly complex problems. Creating new things, for example, is an application of artificial neural networks, such as image composition, music composition, or language composition. Artificial neural networks can be used to help generate structured content at scale, such as financial press releases or statistical blog posts about the day on the stock market.

Most forms of image recognition today use artificial neural networks because of the level of complexity and volume of images. Software which successfully recognizes add categorizes the top 20 different types of photos posted on Instagram everyday would be an example of artificial neural networks in image recognition.

Artificial neural networks are also used in advanced predictive analytics. Any kind of predictive software which requires keeping in memory previous events, as well as classifying those events as recurring or one time, would use artificial neural networks to accomplish the task. These sorts of predictive analytics applications take into account seasonality as well as unusual or irregular events.

Finally, we see artificial neural networks used heavily in conversation, such as with chatbots. The ability for a computer to interact with humans using natural language require significant self-learning and adaptation – two tasks which artificial neural networks excel at.

Deep Learning

To extend the model train analogy, imagine now taking a large toy train set and combining it with many other toy train sets, connecting one train network to the next. How far could our little toy train go if it had miles of tracks from different train networks to run on?

This is effectively what deep learning is, the extension of neural networks to such deep complexity that not only do they simulate the architecture of the human brain, but can replicate many of its abilities. The most famous deep learning implementation currently is Google’s DeepMind; this year, it beat several world Go champions, a feat that many did not expect a computer to be able to do for years, if not decades.

What applications do deep learning have in marketing? None currently, because no marketing tools are sufficiently developed to use deep learning as of this writing. However, the ability for a machine to learn quickly without explicit programming for many tasks holds great promise for marketing. True natural language generation from scratch would be one such application; imagine never having to compose an email again or write a blog post. Want a new best-selling book? A sufficiently advanced deep learning machine intelligence could write one for us.

If we think back to the hierarchy of analytics, after prescriptive analytics comes the fifth and most promising stage: Proactive analytics, when machines read the data, performing analysis, develop insights, and execute a plan without our input. Deep learning will power proactive analytics.

The AI Landscape

Let’s lay out the different machine learning in artificial intelligence technologies in another format to better help understand how the different pieces connect together. As first suggested by my friend and fellow researcher Peta Abdul, let’s compare the evolution of artificial intelligence to human intelligence.

Here, from the Harvard University Center on the Developing Child, is a diagram of how human brains evolve from birth:

In our first year of life, we begin to learn how to process sensory data. We see, we here, we feel, and we build an understanding of the world at a rudimentary level based on our sensory inputs.

As our brains grow in complexity, we develop language skills and ability to communicate by putting together abstract concepts – words – with their real-world representations.

Once we exit early childhood, we develop higher cognitive functions – logic, reasoning, abstraction, creativity.

Let’s rearrange this diagram for machines:

Equivalent to basic sensory processing and inputs is the algorithm, the building block of machine learning. If x happens, y is the consequence.

The equivalent to learning language the various forms of machine learning, supervised and unsupervised. This is where our machines learn without being explicitly programmed to do a task.

After machine learning comes deep learning and neural networks, the equivalent of higher cognitive function in a human being. Abstraction and creativity are the end goals of higher cognitive function for machines in this stage.

There’s one final evolution of machines that is implicit in the human being: Sentience. Futurist Ray Kurzweil calls this the Singularity, the point at which we develop an artificial intelligence that is not only not purpose-built, but is a general-purpose artificial intelligence, a sentient being that can think and reason on its own and function as an independent entity.

How far off the singularity is continues to change; originally, futurists believed we would achieve a sentient artificial intelligence by the year 2100. That time frame has been drastically shortened; Kurzweil believes it may be as soon as 10 years away.

Marketing Implications

Until we reach the singularity, the implications of artificial intelligence on marketing are mostly positive. Many of the tasks we perform as marketers are highly repetitive, not particularly engaging, and require very little creativity, such as creating reports, deploying campaigns, writing content, etc.

As machine learning continues to evolve, we will outsource more and more of these rote tasks to our machines, freeing us up to use our own higher cognitive functions to better effect. We will achieve better results in marketing campaigns with our machine companions; testing, optimization, and analysis will be easier and more effective.

In the next post in the series, we’ll look at marketing applications of artificial intelligence in production today. Stay tuned!

AI Primer for Marketers Part 3: Types of Machine Learning
The most innovative marketers routinely pick up new things, try them out, and succeed or fail. Why are marketers struggling so much to adapt to artificial intelligence and machine learning? In this series, we’ll explore machine learning and artificial intelligence to build a foundation for understanding the field – and how it applies to marketing.

Types of Machine Learning

Machine learning comes in two varieties: supervised and unsupervised. Both kinds of machine learning are important and have different, distinct roles. Let’s investigate each.

Supervised Machine Learning

Supervised machine learning teaches algorithms and software to recognize something. For example, when you use your smartphone to take a picture of something and it automatically recognizes someone’s face and focuses on it, that is a piece of software that has been trained to recognize faces using machine learning.

Supervised machine learning begins by giving a piece of software a known training library and teaching it to recognize things in that library. For example, we’ve used supervised machine learning as consumers for a very long time in our email inboxes. For years, users have marked messages as spam in their inboxes, and machine learning algorithms have learned through training what is and isn’t spam. Every time we mark an email as spam, we help add more to the training library. Over time, assuming we mark messages as spam or not correctly, the algorithms learn what is and isn’t spam.

How would we use supervised machine learning in marketing? We might teach a piece of software to recognize corporate logos and images. We would give it a massive library of corporate logos with logos marked clearly and each photo for the machine to analyze. Over time, the software would recognize more and more logos in the training library until it achieved nearly perfect image recognition of the known good logos.

Once trained, we would then use images that might or might not have logos in them with the algorithm to identify where our corporate logo was used. We would continue to add new logos to the training library so that the machine would continue to learn and grow its capabilities to recognize logos. We’d end up with software which could recognize our logo if someone posted a photo of it on Instagram and didn’t tag us.

Any situation in which we need to recognize or find something is a situation where we would benefit from using supervised machine learning:
- Logo identification
- Mentions of us in social media
- Sentiment analysis
- Influencer identification
- What makes content rank well for SEO
Unsupervised Machine Learning

In comparison to supervised learning, unsupervised learning is all about sorting and classification. We hand a large bucket of stuff to the machines and ask it to sort and categorize it as many ways as possible so that we can then analyze it. Unsupervised machine learning is especially important in today’s giant data world. We create so much content that there’s no way we could ever read even a fraction of it. Only with technologies like unsupervised learning do we stand a chance of analyzing all the content we produce every day.

Imagine you are sitting in front of a table filled with lego blocks. How many different ways can you categorize those blocks?
- You could sort them by color
- You could sort them by shape
- You could sort them by size
- You could sort them by your own personal preferences
If I put 50 blocks on the table, that would be a manageable exercise. If I put 50 billion blocks on the table, you’d run out of lifetime before you are done categorizing and sorting. However, if we gave an image of that table to a computer, it could use unsupervised machine learning to visually categorize the blocks in minutes or even seconds.

How would we use unsupervised machine learning in marketing? Any task which requires sorting and classification is a candidate for unsupervised machine learning. For example, we might collect all the blog posts written about our company and use natural language processing to find out what topics our company is associated with. Are people writing about us using the messaging that we want to be known for? Unsupervised machine learning would break apart all those posts and transform them into a list of topics.

Some other uses for unsupervised machine learning in marketing include:
- sorting images
- understanding social media conversations about us, competitors, or our industry
- clustering and sorting customers to find our best customers
- digesting the day’s headlines to find trending topics to write about
Integrating Machine Learning Types

We would rarely use only one kind of machine learning; most of the time, we will be doing combinations of supervised and unsupervised machine learning. We might, for example, ingest all the social media conversations about a given topic and classify those conversations into sentiment and topics using unsupervised machine learning. We would then use supervised machine learning to find how many of those conversations are about us.

By understanding the different types of machine learning and their uses, we can better understand how they fit into our overall marketing strategy. In the next post in this series, we will take a look at deep learning and how artificial intelligence maps to our own intelligence.

AI Primer for Marketers Part 2: Algorithms and Machine Learning Basics
The most innovative marketers routinely pick up new things, try them out, and succeed or fail. Why are marketers struggling so much to adapt to artificial intelligence and machine learning? In this series, we’ll explore machine learning and artificial intelligence to build a foundation for understanding the field – and how it applies to marketing.

What is Artificial Intelligence?

Before we can begin discussing how artificial intelligence and machine learning will impact marketing, we have to establish some basic definitions.

First, artificial intelligence is the science of creating computer hardware and software that mimics human intelligence and performs human intelligence functions. For example, if you are reading the words on the screen right now and they don’t appear as gibberish, you are using visual recognition and natural language processing, two fields of study in artificial intelligence.

The Basics of AI: Algorithms

The foundation of artificial intelligence, and of computing itself, begins in the algorithm. Named after a 9th century Persian mathematician, an algorithm is a set of repeatable processes that deliver a reliable, repeatable result. We use algorithms every day. Our morning routine is an algorithm. The way we make our coffee is an algorithm. The way we drive to work is a complex series of algorithms.

In marketing, we’ve been using and discussing algorithms since the dawn of digital marketing. Our first experience with algorithms was in SEO, as we tried to figure out what pages ranked well in search engines. We developed our own algorithms for creating content to be found by search engines. Social media marketing is entirely based in algorithms. We talk about them everyday – the Facebook news feed algorithm, the Instagram algorithm, how these platforms choose what content appears to users.

In the basics of computing, algorithms don’t change by themselves. We have to create them and modify them every time something changes. For example, if we’re out of sweetener, we have to change the way we make our coffee. If there’s a traffic jam, we have to change how we drive to work.

What if algorithms could change themselves based on new information?

They can – and that’s what we call machine learning.

The Basics of AI: Machine Learning

Machine learning is exactly as it sounds: the ability for machines to learn without being explicitly programmed. Given new data, a machine can adjust its own algorithms to be more efficient or more effective.

For example, we use machine learning every time we use our smartphone GPS. We put in our destination and the GPS finds the most efficient route for us. If traffic conditions change, our GPS changes along with those conditions and finds us a new way to get to where we’re going.

As consumers, we’ve had experience with machine learning since the early days of a digital marketing. Every time a platform or a service remembers our preferences and changes with them, we are seeing machine learning at work. Every time we shop online and a website gives us a list of recommendations that get better and better the more it gets to know us, we are seeing machine learning at work.

The foundations of machine learning are in algorithms and statistics. For example, when we are shopping online and a website is deciding what to show us as a recommended item to go along with our purchase, the machine learning algorithm is running a series of statistical tests.

Based on past experience and what other customers bought, what is the probability that we will like and purchase the red item versus the blue item? each time we purchase something, the website learns and scores its previous statistical test.

If it succeeded in convincing us to buy something additional in our order, then it updates as probability calculations for the next customer and for the next time we come back. If it didn’t convince us to buy something, then it will rerun its statistical tests to find what else we might purchase instead.

Next: Types of Machine Learning

In the next post in this series, we will look at the different types of machine learning and how they apply to marketing. Stay tuned!

AI Primer for Marketers Part 1: Why AI/ML is Harder
The most innovative marketers routinely pick up new things, try them out, and succeed or fail.
- When email became popular in the late 1990s, innovative marketers latched onto it.
- When websites and SEO surged in popularity in the early 2000s, marketers were there.
- When social media picked up in the mid-2000s, marketers cranked out the MySpace pages with reckless abandon.
- When consumers pivoted to mobile devices in the early part of this decade, marketers squeezed messages into tiny screens and apps.
So, given that marketers have a solid track record of adapting to new realities, why are marketers struggling so much to adapt to artificial intelligence and machine learning?

Two Challenges of Artificial Intelligence and Machine Learning

Marketers face two challenges with AI that they didn’t face with prior new technologies.

First, AI isn’t a consumer technology. The end consumer isn’t an artificial intelligence; the end consumer remains largely the same. What has changed is that the conduit to the consumer is now powered by machine learning and AI, from social media algorithms to screenless assistants. As a result, marketers face a new intermediary, rather than a new direct channel to the consumer. The closest analogy to this situation is the advent of SEO in the early 2000s, when marketers needed to understand how SEO worked – and SEO for search engines was radically different than the way consumers searched for things. Back in the early 2000s, SEO for machines was very different than SEO for people. Today, thanks in part to AI, they are largely the same thing.

Second, AI and its underpinnings are deeply entrenched in mathematics and statistics – two fields which are not strong points for most marketers. For example, let’s consider one of the most powerful and common ensemble machine learning technologies available today: the random forest. To understand the random forest and its value, we must first understand the decision tree – and everything that typically goes wrong with decision trees. To understand the decision tree, we must understand statistics and probability.

The Difference Between Math and People

When we compare statistics to communications, we see the stark difference between AI and other new technologies. When consumers use social media, email, or mobile devices, at the end of the process we are still interacting with another human being. We can transfer our domain knowledge of how people interact from one medium to the next.

When we try to tackle AI, we now switch from people as the end interaction point to machines and mathematics, areas which marketers typically have less experience.

What this means for us is that we shouldn’t feel bad if we’re struggling to incorporate AI and its various component technologies into our marketing. If you’ve been feeling left behind or out of the loop in all the AI hype, understand that it’s not because you’ve failed as a marketer. You’re not a mathematician, statistician, data scientist, or programmer. Know that to adapt to the new AI landscape, you’ll simply need to hire these people to complement your marketing and domain expertise in humanity.

Next: Basics of Machine Learning Technologies

In the next post in this series, we’ll look at the basics of machine learning technologies, define artificial intelligence more clearly, and help build your knowledge of how AI and Machine Learning fit into marketing.

Incentives, Solutions, and Machine Learning
Traditional economic wisdom about solving problems and incentives says:

We get what we pay for.

As a logical corollary, we don’t get what we don’t pay for.

This is known as opportunity cost. We focus on what we want, and leave behind the things we judge less important.

At a small level, this is an entirely sensible philosophy that we use to guide our everyday decision-making. If we’re hungry and we pay for Thai food for lunch, by extension we are not paying for a burger and fries. This is an acceptable trade-off; at the conclusion of the meal, we shouldn’t be hungry.

However, when we apply this philosophy to bigger decisions, we often create unintended consequences. For example, if we decide feeding the hungry and poor is a focus, we might invest in food programs. However, in doing so with such a single minded focus, we might underinvest in jobs programs. In this scenario, it’s easy to see that cutting investment in jobs programs will likely have the unintended consequence of creating more poor, hungry people.

The reality is that complex issues rarely have a single solution. Most often, complex issues have extremely complex solutions, ones which we humans struggle to understand and solve. The good news is that artificial intelligence and machine learning may be able to solve these problems better than we ever could.

A simplistic example of this is the decision tree, a type of statistical analysis very common in machine learning. Decision trees help us to understand what choices lead to the outcome we seek; in virtually every case, using a decision tree system will yield multiple ways to achieve an outcome:

In the simplistic SEO example above, I built a decision tree to evaluate what makes a link authoritative and trustworthy using Moz data and IBM Watson Analytics. No one variable – no one easy solution or incentive – in the model governs trustworthiness of a link; rather, a combination of variables likely drives trust – and several models exist. I’d turn this analysis into a usable outcome by building an SEO marketing program around the data and testing to see which model generates the best results.

For our largest societal problems, we’d use similar analysis but at a much larger scale, and with machine learning to take outcomes and feed them back into the model to improve it continually. While we can solve for SEO problems in just a few iterations, solving something like poverty will likely require massive computational resources and years to do the analysis – but it’s possible, within our reach.

If we do this, we will better understand that no one incentive or solution will fit a complex problem. Building and sharing this understanding will help reduce “quick fix” solutions everywhere, from marketing to business to politics. If we build well, the rise of the machines may well lead to the rise of a new, better civilization.
