How Machine Learning Introduces Unconscious Biases
What constitutes an unacceptable real-world bias? We might argue that any perspective which unfairly disadvantages someone based on non-material criteria is an unfair bias. For example:
- Choosing one job candidate over another due to skin color or “ethnic-sounding names”
- Setting different pricing for one customer over another because of religious views
- Paying one person less than another despite equal performance due to gender
- Wrongfully terminating someone without cause due to sexual orientation
All of the above scenarios are generally regarded as illegal and unacceptable in modern business. Companies which willfully implement policies which enable the above behaviors face severe consequences, as they should.

What if our machines are learning these behaviors from us in an unconscious way?

How Machines Learn

The basic process of training a machine learning system goes something like this:
1. Gather data
2. Clean data
3. Engineer features
4. Choose algorithms
5. Test algorithms
6. Select model
7. Test model
8. Refine model
9. Operationalize model
What’s happening in the process is that we give machines the data we want them to learn from (steps 1-2), tell them what data to use (3), then help them decide how they’ll learn (4-8). Once the machine has learned and is generating good results, we release it into production (9).

When data scientists execute the machine learning process above, they spend the vast majority – 60-80% – of their time on steps 1 and 2 (according to data scientist David Langer). They spend a minority of time on step 3 (~20%), and invest their remaining time on steps 4-9.

Consider the process we just outlined. Is it any surprise that companies rush to step 9 as quickly as possible in order to start achieving ROI?

Is it any surprise that the crops of brand new data scientists, fresh out of university classes or professional development courses, spend most of their time and energy studying algorithms and modeling?

These are natural human tendencies – to want to do the cool stuff, to want to achieve results as quickly as possible for maximum gain.

Where Bias Creeps Into Data Science

Where bias creeps in, however, is in feature engineering. During feature engineering, we choose and shape the data for the algorithms we’ll expose it to. Bias creeps into data science because we breeze past feature engineering as quickly as possible to “get to the good stuff”.

Consider this simple dataset for a fictional HR recruiting database:
- Name
- Age
- Ethnicity
- Gender
- College or University Attended
- Last Company Employer
- Last Company Employer Separation Date
- Number of LinkedIn Recommendations
- Number of LinkedIn Endorsements
- Last Job Applied For
- Last Job Applied For Date
- Last Website Visit Date
- Last Email Opened Date
- Number of Clicks in Last Email
Suppose our mission as data scientists was to develop a machine learning model that could predict who we should hire.

An inexperienced data scientist might look through the database to find missing or corrupted data, then load the entire dataset, as is, and start testing algorithms. They’d select some of the best-known algorithms and dig right into building a model, find a model that generates what looks like statistically accurate, relevant results, and hand it off to the business user triumphantly.

Do you see the problem?

What the machine might learn from this dataset is that a predictor of who to hire might be white men, aged 31-36, who have more than 20 LinkedIn endorsements. The model would then recommend only job candidates who fit that criteria.

While that model might be statistically valid, it’s also illegal. Age, ethnicity, and gender should not be considerations in a hiring model. Yet the inexperienced or rushed data scientist skipped past feature engineering, the critical stage at which those invalid fields would have been removed. That data would not and should not be a part of the machine learning model.

What Should Have Happened

The experienced data scientist would know to invest lots of time in feature engineering to explicitly screen out potential bias from our training data. If our hiring data to date has a past human bias of not hiring women at the same rate as men, our machine learning model would learn to emulate that behavior unless we explicitly removed gender from consideration.

What should have happened is that we should have removed any data which could have led to an illegal outcome, an illegal model.

The important part here is that we did not intentionally create bias. We did not set out to willfully discriminate against one group or another. However, historically we may have, especially if we use large longitudinal datasets that span decades. Our inexperience, our haste, or our inability to recognize situations involving potential bias caused the problem.

Now, the dataset example above is just a handful of criteria. Imagine a dataset with thousands of columns and millions of rows, something we cannot physically remember. It’s easy to see how bias could creep in if inexperienced or rushed data scientists are building models from massive datasets.

The great danger here is that in many machine learning applications, the end user never sees the model, never sees the code, never sees the training data. Thus, we may be working with biased models and not know it until months or years later when we start seeing unexpected trends in our results.

Protecting the Future of AI, Protecting Our Future

If AI is to have a permanent, valuable place in our society in the years and decades to come, we must rigorously oversee the creation of its models. We must tell it what is explicitly forbidden, and train it to recognize biases conscious and unconscious. If we do that well, we will create a more fair, more just, and more pleasant society as our machines guide us away from our baser instincts.

Why AI Presents A Potential Income Inequality Problem
Artificial intelligence poses a future potential problem in the exacerbation of income inequality, much in the same way that automation and robotics creates an income inequality problem today.

The Old Way of Making Money

In the days before automation and robotics, factories hired humans to do repetitive, boring, and dangerous tasks. Factory owners sold their goods, keeping a chunk of the profits for themselves, and passing the rest along to workers. In exchange for performing tasks, workers were compensated for their labors.

What did those workers then do? They went out into the world and spent their pay. They bought groceries, paid rent, drove cars, and so on. These workers – and their compensation – fueled the economic growth of the Industrial Revolution and beyond.

When Robots Arrived

Factory owners attempted to find ways to optimize worker productivity over the decades, until the era of robotics arrived in force in the 1990s. Suddenly, tasks performed by humans could be performed by robots instead at greater speeds, with fewer errors, and in environments that were hazardous to humans. The net effect? Job losses. According to the National Bureau of Economic research’s 2016 working paper, one new industrial robot coincides with an employment drop of 5.6 human workers:

What happens to those 5.6 workers? They no longer spend money until they find new employment. Meanwhile, the factory owner reaps increased profit margins because they spend less on an ongoing basis for the same or better merchandise.

The net impact is increased income inequality. The factory owner makes more money while the workers make less – or none.

The Potential AI Problem

As we’ve discussed in the past, AI promises automation of cognitive work in the same way that robots promised and delivered automation of manual work. Filing expense reports, correcting timesheets, updating stock portfolios – there are thousands of repetitive tasks in every cognitive job that are ripe for automation.

As we saw with industrial robots, industrial AI could remove significant portions of labor from all kinds of jobs, so much so that jobs could be consolidated. Instead of accounting, HR, finance, and marketing employing dozens or hundreds of people, with general purpose AI, we could see just a handful of office managers or leads overseeing thousands of AI instances doing the same work – and doing it better than their human counterparts ever did.

The outcome will be similar to robotics, with one significant exception: industrial robots have a substantial capital investment up front for a very expensive robot. AI has significantly lower costs for what are effectively intangible functions performed as a service. Anyone who has ever set up a new cloud computing instance knows how quick and easy it is to provision a new service – just a few clicks of a mouse and a new virtual machine is ready to go in minutes, if not seconds. Thus, while one robot replaces 5.6 human workers, one AI could replace many more office workers.

The net effect will be even sharper income inequality. Company owners and officers will enjoy significantly improved profit margins and far less overhead. But what of the armies of secretaries, accountants, marketers, and HR staff? The number of jobs available to them will diminish over time, magnifying income inequality.

The Consequences of Income Inequality

When income inequality becomes sharp enough, a predictable outcome occurs in the historical record: revolution. From Mao Zedong to Vladimir Lenin to Napoleon Bonaparte to Adolf Hitler, revolutions resolve income inequality through significant, even catastrophic, loss of life.

Possible Solutions

A number of solutions have been proposed to fix the income inequality problem specific to technology, from universal basic income to robot taxes.

The key to any solution is reminding the upper end of income and property holders that redistribution of income is in their long-term interests. In Dr. Robert MacCulloch’s 2005 paper, “Income Inequality and the Taste for Revolution”, he found:

Although property rights are the cornerstone of market economies, throughout history existing claims have been frequently overturned by revolutions. One unsettled question is whether income inequality affects the likelihood of revolt. This paper takes an approach different from previous studies by introducing data derived from two surveys of revolutionary preferences across a quarter‐million randomly sampled individuals. More people are found to have a preference for revolt when inequality in their nation is high. A 1‐standard‐deviation increase in the Gini coefficient explains up to 38 percent of the standard deviation in revolutionary support. The results hold after controlling for a set of personal characteristics and country and year fixed effects. Since higher levels of income are found to have a negative impact on the taste for revolt, the results suggest that either “going for growth” or implementing policies that reduce inequality can buy off those individuals with revolutionary preferences.

Of the solutions proposed, universal basic income appears to be the most viable; governments print inflationary amounts of currency anyway, and income redistribution is an easier sell than direct taxation of businesses.

Whatever we choose as a society to solve for income inequality, we must choose sooner rather than later. AI will drastically shift income in our current economic setup, paving the way for civil unrest or worse.

How to Tell What’s Real and What’s Hype in AI
AI is the hot topic of discussion now, and it’s understandable for people to wonder just how much of the talk is hype and how much is real. Go to any tech trade show or conference and AI is splashed across every vendor’s product descriptions. Read the news headlines and one would be excused for thinking robots were going to take over the world any minute now.

How much of the hype is real? The easiest way to make this determination is with one question:

“Are you actually doing that?”

When we read an article talking about AI, machine learning, or deep learning, and there’s no demonstration or sample code in the article, the obvious question to pose is whether the person is actually doing the work, practicing what they’re talking about.

The quickest way to differentiate theory from application is to ask about how any given technology is currently used in production.

For example, I was at the MarTech SF conference recently and one of the vendors, Amplero, was making all kinds of claims about how their technology used sophisticated AI to improve marketing automation. When I cornered their CEO and asked what specific technologies they were using, he showed me how they were using scikit-learn’s random forests to winnow down what variables were relevant in lead scoring. Once he showed just a glimpse of the production code (without revealing any of the secret sauce), it was clear they had the goods to back up the talk.

What’s Real in AI for Marketing (for me)

What’s working for me right now, in production? I use three distinct technologies from artificial intelligence and machine learning in my day-to-day work:
- Natural language processing (NLP). This is machine learning technology built around recognizing and categorizing large bodies of text. For example, I recently did a B2B landscape survey and crunched 750,000 tweets and 25,000 articles with NLP for a client at work. It would have taken me ages to do the same manually. For analyzing text at scale, NLP is the way to go. My favorite technologies for NLP right now are NLTK in Python and IBM Watson Natural Language Understanding.
- Random forests and dimensionality reduction. These are techniques to help reduce the complexity of a dataset or understand what’s relevant and what’s not. Random forests are especially powerful for marketers who face a deluge of data – out of all the analytics we have, which drive our program objectives? I’ve been working with random forests and dimensionality reduction technologies since mid-2016 and the available software keeps getting easier and better. Lately I’ve been feeding a year’s worth of every marketing data point available and asking the software to tell me what matters in terms of reaching my objectives. The best tools I’ve found in this space revolve around the R project.
- Speech recognition. Speech recognition is all about taking the spoken word and turning it into text; once in text form, we perform NLP on it. The best services cost pennies or less per recorded minute, and so much value is locked up in non-searchable audio. Think of everything we listen to in marketing – conference calls, speeches, presentations, etc. – and how much of that knowledge is locked away from search. I use speech recognition to turn client calls into transcripts, speeches into blog posts, and so much more. The best tools right now for speech recognition are IBM Watson Speech to Text and Google Cloud Speech API.
You’ll notice that my use cases for AI right now are far, far away from the vision of Terminators and Skynet. AI is helping me solve problems and be more efficient, but in no way is replacing me or my job. Instead, it’s tapping into reserves of data that I didn’t previously have the ability to access, like a gold miner buying their first excavator after only having picks and shovels. It’s making me more valuable by unlocking additional value rather than replacing human value, and that’s likely to continue being the case for the short to medium term future.

If your organization is sitting on data that has untapped potential, then ignore the hype about AI and dive in. Start testing, prototyping, and experimenting with all that unrealized value. Your organization’s future – and your future – depend on it.

The Power of Predictive Analytics and SEO Data
Few things are as compelling to marketers as the promise of prediction. Every marketer wants to know what will happen; what has happened is of less interest because we can’t change the past. If we knew what was likely to happen, we could plan in advance for it.

Suppose we knew what was going to happen next year in organic search for our industry. What would we do differently?
- Would we create different content?
- Would we augment our organic content with paid amplification?
- Would we share our content more aggressively on social media before peak season?
Whatever choices we’d make, knowing in advance would allow us to plan ahead.

A Very Brief History of Predictive Analytics

Predictive analytics aren’t new; data scientists have been working with predictive software since the 1940s. However, until recently, marketers haven’t had access to the power of predictive analytics because the technology was locked away in statistics and IT. With the democratization of statistical software, marketers now have access to a treasure trove of powerful predictive tools – and 70 years of proven, tested methodologies.

Today’s predictive analytics tools use algorithms and machine learning techniques to generate accurate, durable, resilient predictions – and at very low cost. Software packages like the R Project and Python are open-source and free of financial cost, available to any marketer.

Example: NYC Tourism

Let’s look at an example of how we’d mix predictive analytics and SEO to power a tourism marketing program. Suppose we’re the managers of New York City’s convention and visitors’ bureau. What would we want to know about tourism in our city?

Based on some quick keyword searches in any competent SEO tool, we’d look at searches like “flights to NYC”. People generally don’t search for intent-based phrases like that unless they have some intent to visit NYC by plane. Next, let’s obtain the actual keyword volume for that search and chart it out:

So far, so good: we see weekly keyword searches for “flights to NYC” for the last 5 years. As a tourism manager, we see the search volume on the rise – that’s good news for us. However, we’re still stuck in the past. We’re still looking backwards. Let’s use the R programming language and any one of the major time forecasting packages available to project forward:

Next, let’s make this a bit more marketing-friendly to understand:

We now have a calendar of operations. For times when we have peak search demand, we could run additional advertising and paid campaigns to double down on popular times.

For times when we have declining searches, we could take the time to improve our on-site content or work with a public relations agency to improve general brand awareness (which powers branded organic search).

We could even advise our business partners – NYC hotels and other venues – to forecast demand appropriately. Hotels could ensure they have enough rooms available for peak times, and plan sales for when demand is weaker. Restaurants could plan a restaurant week when demand is low to keep revenues coming in steadily, rather than be surprised at weaker-than-expected periods of tourism.

No matter what tactics we choose, knowing the organic search volume in advance helps us to plan our resources, staffing, budgets, and timing appropriately. Instead of reacting to recent search data, we look ahead to the future. Instead of scrambling, we plan calmly and methodically to ensure maximum impact.

The Future, Today

Predictive analytics is within our reach as marketers. Use the tools and data we already have access to and project ahead likely outcomes, from SEO data to social media data to hard dollar revenues.

Obviously, no amount of predictive analytics can anticipate black swan events like a meme going viral or a negative news event, but the vast majority of businesses rarely face black swans. Most of what we do as marketers is highly repetitive, and thus very predictable.

Get started with predictive analytics using R or Python and start building next year’s marketing plan today!

Speech Recognition and Transcription Services Compared
Many marketers have a need for transcription of audio and video data, but the prices and quality on the market vary wildly. Let’s compare the options and look at the transcription/speech recognition landscape to see what fits our marketing needs best.

Why Transcription?

We face more and more rich media content as marketers – audio, video, and interactive media. Yet most of our organic search value comes from good old plain text – words on a page. To make the most of the rich media we have, we need to convert the spoken words in our rich media into plain text for use in blog posts, eBooks, email, and other searchable content.

Transcription is the best way to accomplish this goal. Transcription helps us take advantage of existing content, rather than re-invent the wheel every time we need text-based content. The average person speaks at approximately 150 words per minute; the average blog post has approximately 300 words. Just two minutes of high-quality speaking could yield a blog post that might take a mediocre author an hour to draft. If we leverage the great audio and video content we’ve already created, we can make our content work harder for us in multiple formats.

The Transcription Landscape

Now that we understand why transcription matters, let’s look at the landscape of services available.

Human-powered transcription costs anywhere from $1 -$ 3 per minute of recorded audio, and the results are usually top-notch because human beings have excellent voice recognition. Even outsourced, overseas transcription services generally yield good quality, especially for non-technical speech.

Professional automated services – usually with human supervision or quality checking – offer costs anywhere from $0.25 -$ 1 per minute of recorded audio, and the quality is decent. A machine takes the first pass at the audio, then a human cleans up anomalies in the transcription.

Finally, fully-automated, AI-based transcription services such as IBM Watson and Google Cloud offer somewhat accurate transcription services for 1-2 pennies per minute of recorded audio. While the accuracy isn’t as good as human-assisted or human-powered, the cost savings are considerable.

Let’s look at what a one minute file of top-notch audio quality turns into with a few different services. Here’s the raw audio file if you’d like to compare:

Professional Automated Service

This is an example of a typical type of voice file that you would want to transcribe. As one speaker it has words that someone would use while they were musing about a particular topic while they were thinking out loud. There’s some background noise from the environmental variables. There are the usual starts and stops and. Other background noises or file noise as you would expect from human communication that are part of conversation and part of the way people talk. And in particular if you are transcribing from a recording of some kind from a meeting or a phone call or a conference speech you’re going to get these kinds of background noises. So with this we’re going to test this out to see just how it sounds rather just how well each transcription service does with sort of a bake off if you will between one or more cognitive services. This file has been leveled using Adobe Audition So Reed is as good as it gets when it comes to audio quality and the microphone was a little boom microphone. That’s a boom condenser. So it’s very close to the speaking source. This is as pristine as you’re going to get when it comes to audio recordings especially when you’re dealing with stuff like conference calls where the microphone quality is is low to say the least. So let’s see what comes out when we run this through a couple of different voice recognition services.

Google Cloud

Verdict: Use IBM Watson for Transcription

When it comes to the balance of quality and cost, IBM Watson’s speech recognition is the winner. The transcript is fairly accurate, the cost is 2 cents per recorded minute, and it’s in a usable format. Google Cloud is cheaper but it returns a literal pile of words – no punctuation or language recognition of any kind. The commercial service returns reasonably clean text with punctuation, but the accuracy isn’t much better than Watson – and certainly not 12.5x better, which is how much per minute more it costs.

For what the average marketer needs, IBM Watson is the way to go right now when it comes to transcription for content marketing purposes. Give it a go and see how it does with your content.

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.

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.

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.
