    Chief Data Officers, AI, ML, and Influencers on The Cube

    I joined an all-star team of IBM social influencers to speak on Silicon Angle’s The Cube at the IBM CDO Summit recently. We discussed artificial intelligence, machine learning, neural networks, predictive analytics, and so much more. Hear what Tripp Braden, Mike Tamir, Bob Hayes, and I had to say:

    Thanks to IBM and Silicon Angle for having us!

    Closed Caption Auto-Transcript:

    live from Boston Massachusetts
    it’s the queue coverage IBM chief data
    officer summit brought to you by IBM
    welcome back to the cubes live coverage
    of IBM’s chief data a strategy summit
    I’m your host Rebecca Knight along with
    my co-host Dave Vellante we have a big
    panel today these are our social
    influencers starting at the top we have
    Christopher Penn VP Marketing of shift
    communications then Tripp Braden
    executive coach and growth strategist at
    strategic performance partners Mike
    Tamir chief data science officer
    attacked Bob Hayes president of business
    over Broadway thanks so much for joining
    us thank you yeah so so we’re talking
    about data as a way to engage customers
    a way to engage employees what what
    business functions would you say stand
    to benefit the most from using from
    using data nothing too active that if
    it’s the biggest function but I think
    that the customer experience and
    customer success how do you use data to
    help predict what customers and
    customers will do and how do you then
    use that information to kind of
    personalize that experience for them and
    drive up recommendations retention
    absolutely things like that so it’s
    really it’s really the customer
    experience that you’re focusing on yes
    and I just just released a study I found
    that that analytical leading companies
    tend to use analytics to understand
    their customers more than say analytical
    a Gerdes so those kind of companies who
    can actually get value from data they
    focus their efforts around improving
    customer loyalty and just gaining a
    deeper understanding about their
    customers Chris do you want to jump in
    here and you say as many of us said do
    the weave have 3 things you really care
    about us as business people right we
    want to save money save time or make
    money and so any function that those
    company that meets those qualifications
    are this function will benefit from data
    I think there’s also another engineer
    interesting dimension to this when you
    start to look at this the leadership
    team in the company now having the
    ability to anticipate the future I mean
    now this we are no longer just looking
    at static data but we are now looking at
    anticipatory capability and seeing
    around corners so that the person comes
    to the team they’re bringing something
    completely different than the team in
    them has had in the past
    this whole competency of being able to
    anticipate the future and then take from
    that where you take your organization in
    the future so so follow-up on that trip
    just does this data now finally trump
    gut feel remember the HBR article of
    10-15 years ago can’t beat gut feel is
    that we hit a new era now well I think
    we’re moving into an era where you have
    both I think it’s no longer neither or
    you happen to wish you know we have data
    now we have both the organization’s who
    can leverage both at the same time and
    develop that capability and earn the
    trust of the other members by doing that
    that I see the chief data officer really
    being a catalyst for organizational
    change so dr. Tim another one if I get
    asked you a question maybe the whole
    panel but so we’ve all followed the big
    data trend and and the meme AI deep
    learning machine learning same wine new
    bottle or is there something substantive
    behind it or our capabilities are
    growing our capabilities and machine
    learning and I think that’s part of why
    now there’s this new branding of ai ai
    is not what your ear what your mother
    might have thought is it’s not robots
    and Cylons and that sort of thing that
    are going to that are going to be able
    to think intelligently they just did
    intelligence tests on I’m too different
    like Siri and Alexa quote a eyes from
    different companies and they port at
    least be scored horribly that they
    scored worse than in my mind what much
    worse than mice very intelligent
    seven-year-old and that’s not a comment
    on
    the deficiencies in the in Alexa or in
    serious a comment on these are not
    actually artificial intelligences these
    are just tools that apply machine
    learning strategically so who you are
    all thinking about data and how it is
    going to change the future and one of
    the things you said trip is that we can
    now see the future it talked to me about
    some of the most exciting things that
    you’re seeing that companies do that are
    anticipating what what what what
    customers want okay so for example in
    the customer success space a lot of SAS
    businesses have a monthly subscription
    so they’re very worried about customer
    churn so companies are now leveraging
    all the user behavior to understand
    which customers are likely to leave next
    month and if they know that they can
    reach out to them with maybe some
    retention campaigns or even even use
    that data to find out who’s who’s in the
    who’s most likely to buy more from you
    in the next month and then market to
    those and effective way so don’t just do
    a blast for everybody focus on
    particular customers their needs and and
    try to service them or market to them in
    a way that resonates with them that
    increases retention of selling and
    recommendations so they’ve already seen
    certain behaviors that show a customer
    is maybe not going to exactly so she
    just you throw this data and machine
    learning right you find the predictors
    of your of your outcome that interests
    you and then using that information you
    see oh maybe predictors a B and C are
    the ones that actually drive loyalty
    behaviors they accuse an information to
    segment your customers and market to
    them appropriately it’s pretty nice
    pretty cool stuff
    February 18th 2018 okay so we did a
    study recently just for fun of when
    people search for the term outlook
    out-of-office
    yeah and you really only search for that
    term for one reason you’re going on
    vacation and you and you want to figure
    out how the trends feature on so we did
    a five year data poll of people with a
    search box with it and then inverted it
    so when do people search least for that
    term that’s when they’re in the office
    and it’s the week of every 18 2018 will
    be that time when people like yeah
    I mean I’m at the office saying I work
    and knowing that the prediction and day
    to give us specificity like yeah we know
    the first quarter is busy we know
    between Memorial Day and Labor Day is
    not as busy in the b2b world but as a
    marketer we need with specificity data
    and predictive analytics gives us
    specificity we know what week to send
    our email campaigns what week to turn
    our ad budgets all the way to fall and
    so on and so forth if someone’s looking
    for the cue when do when will they be
    doing that you know going forward that’s
    the power of this stuff is that
    specificity we’re gonna search for word
    before we searching I’d like to know
    where I’m gonna be next week why that
    date do not see the date that people
    least search for the term outlook out of
    office okay so they’re not looking for
    that feature which logically means
    there’s a good point on not just what
    you’re predicting for interactions right
    now but also anticipating the trends so
    Bob brought up a good point about
    figuring out when people are turning to
    the flip side of that which is how do
    you get people to be how do you get your
    customers to be more engaged and now we
    have really an explosion in the
    enforcement learning in particular which
    is a tool for figuring out not just how
    to interact with you right now as a
    one-off statically but how do I interact
    with you over time this week next week
    the week after that and using
    reinforcement learning you can actually
    do that this is the sort of technique
    that they used to beat alphago or to be
    humans with alphago machine learning
    algorithms supervised learning works
    well when you get that immediate
    feedback but if you’re playing a game
    you don’t get that feedback that you’re
    gonna win 300 terms from now right now
    you have to create more advanced more
    advanced value functions in ways of
    anticipating where things are going this
    move so that you see that you’re on
    track for winning and 20-30-40 moves
    down from down the road and it’s the
    same thing when you’re dealing with
    customer engagement you want to
    you can make a decision I’m going to
    give this customer coupon that’s going
    to make them spend 50 cents more today
    or you can make decisions
    algorithmically that are going to give
    them a 50 cent discount this week next
    week then the week after that that are
    going to make them become a coffee
    drinker for life or customer for life
    it’s about finding those customers for
    life IBM uses the term cognitive
    business we go to these conferences
    everybody talks about digital
    transformation at the end of the day
    it’s all about how how you use data so
    my question is if you look think about
    the bell curve of organizations that you
    work with how do they you know what’s
    the shape of that curve part one and
    then part two is where do you see IBM on
    that curve well I think a lot of my
    clients make a living predicting the
    future their insurance companies their
    financial services that’s where the CDO
    currently resides and they get a lot of
    benefit but one of the things we’re all
    talking about but talking around is that
    human element so now how do we take the
    human element and incorporate this into
    the structure of how we make our
    decisions and how do we take this
    information and how do we learn to trust
    that and the one thing I hear from most
    of the executives I talk to when they
    talk about how data is being used in
    their organizations is the lack of trust
    now when you have that and you start to
    look at the trends that we’re dealing
    with and we call them data points but
    she’s calling them people now you have a
    problem because people become very
    almost anonymity analytically challenged
    right so how do we get people to start
    saying okay let’s look at this from the
    point of view of it’s not a neither or
    solution in the world we live in today
    cognitive organizations are not going to
    happen tomorrow morning even the most
    progressive organizations are probably
    five years away from really deploying
    them completely but the organizations
    would take a little bit of an edge so
    five 10% edge out of there
    they now have a really a different
    in their markets and that’s what we’re
    talking about hyper critical thinking
    skills I mean when you start to say how
    do I think like Orrin Buffett how do I
    start to look and make these kinds of
    decisions analytically how do I sit how
    do I recreate an artificial intelligent
    machine learning practice and in program
    that’s going to solute profit solution
    for people and that’s where I think
    organizations that are forward leaning
    now are looking and saying how do I get
    my people to use these capabilities and
    ultimately trust that the data that
    they’re told
    so I forget who said it but it was early
    on in the big data movement somebody
    said that we’re further away from a
    single version of the truth and than
    ever and it’s just gonna get worse but
    so was the data scientist Oh what say
    you not familiar with the truth code but
    I think it’s very relevant and very
    relevant to where we are today with
    there’s almost an arms race you hear all
    the time about automating putting out
    fake news putting out misinformation and
    how that can be done using all the
    technology that we have our disposals
    for dispersing that information the only
    way that that’s going to get solved is
    also with algorithmic solutions with
    creating creating algorithms that are
    going to be to be able to detect is this
    news is this something that is trying to
    attack my emotions and convince me just
    based on fear or is this an article
    that’s trying to present actual facts to
    me and you can you you can do that with
    machine learning algorithms but of now
    we have the technology to do that better
    algos them like and share from a
    technological perspective to your
    question about where IBM is IBM has a
    ton of stuff that’s called AI as a
    service essentially where if you’re a
    developer on bluemix for example you can
    plug in to the different components of
    Watson at literally pennies per usage to
    say I want to do sentiment Alice I want
    to do tone analysis I want personality
    insights about this piece of know who
    wrote this piece of content
    and to dr. communes point this is stuff
    that you we need these tools to do
    things like you know fingerprint this
    piece of text did the supposed author
    actually write this you can tell that so
    of all of the the format I recall the
    Microsoft Amazon Google IBM getting on
    board and we’re adding that five or ten
    percent edge that that trip was talking
    about is easiest with IBM bluemix great
    one of the other parts of this is you
    start to talk about what we’re doing and
    you start to look at the players that
    are doing this they are all
    organizations that I would not call
    classical technology organizations they
    were 10 years ago you look at the
    Microsoft but you look at the leadership
    of Microsoft today and they’re much more
    about figuring out what the formulas for
    successful business and that’s the other
    place I think we’re seeing a
    transformation occurring and the early
    adopters is they have gone for the first
    generation in the pain you know of
    having to have these kinds of things and
    now they’re moving in that second
    generation where they’re looking for the
    game and they’re looking for people can
    bring them capability and have the
    conversation and discuss them in ways
    that they can see the landscape I mean
    part of this is we could get caught in
    the bits and bytes you missed landscape
    pitches should be seeing in the market
    and that’s where I think there’s a
    tremendous opportunity for us to really
    look at multiple markets off the same
    data and imagine looking and saying
    here’s what I see everyone in this group
    would have a different opinion in what
    they’re saying but now we have the good
    to see at five different ways and share
    that with our executive team and what
    we’re seeing so we can make better
    decisions I wonder if we could have a
    frank conversation honest conversation
    about the data and the data ownership
    you heard IBM this morning saying we’re
    gonna protect your data but I love you
    guys as independents to weigh in you got
    this data the data you guys are involved
    with your clients building models the
    data trains the model I got I kind of
    believe that that model gets used at a
    lot of different places within an
    industry like insurance or across retail
    whatever it is so I’m afraid that my
    data is gonna my IP is gonna seep across
    the industry should I not be worried
    about that I wonder if you could guys
    could weigh in well if you work with a
    particular vendor sometimes vendors have
    have a stipulation that we will not
    share your models with other clients so
    then you just got to stick to that so
    I mean but in terms of science and you
    build a model right you want to
    generalize that to other businesses so
    so maybe if you could work with work
    somehow with your existing clients say
    here just this is what you want to do
    you just want to you’d want to elevate
    the water for everybody right so
    everybody wins when all boats tries
    right so if you can get that if you can
    kind of convince your clients that we
    just want to help the world be better
    and function better make employees
    happier customers happier let’s let’s
    take that approach and and just use the
    models in a that maybe generalize to
    other situations and use them and if you
    don’t then you just don’t launch a
    transparent about it exactly good yeah
    I’m not super you David and Tripp and I
    are all dressed similarly right we have
    the model of if I put on your clothes we
    wouldn’t but if I were to put on clothes
    it would not be you it’s the same model
    it’s just not gonna be the same outcome
    it’s gonna look really bad okay so yes
    companies can share the models and that
    the general flow is tough but there’s so
    much if a company’s doing machine
    learning well there’s so much feature
    engineering that unions then company
    they’re trying to apply that somewhere
    else just gonna blow up
    yeah we could switch ties
    Chris Tripp Mike and Bob thanks so much
    for joining us this has been a really
    fun and interesting panel thank you very
    much thanks you guys we will have more
    from the IBM Summit in Boston just after
    this

  • The Predictive Analytics Process: Plan

    The Predictive Analytics Process- Plan

    In the last post, we examined the output of an S-ARIMA-based prediction. Let’s now dig into the most important part of predictive analytics: planning and acting.

    The Predictive Analytics Process: Plan 1

    The Power of Predictive Analytics

    The power of predictive analytics is our ability to forecast with greater accuracy and specificity than generalized, “gut instinct” predictions. We know when something will happen and the magnitude of it.

    However, none of this incredible power means anything if we fail to act. If we build a predictive forecast that sits in a desk drawer or at the bottom of our email inbox, then our power is wasted. We may as well have done nothing at all and played video games or watched Netflix instead.

    Before you create a predictive analytics forecast, ask, “Will we actually use this?”. If the answer is a resounding yes, then proceed. If the answer is anything but yes, find out why.

    • Did we not establish the credibility of the forecast?
    • Did we not establish the output of a predictive forecast?
    • Did we not establish the value, the outcome, of following a predictive forecast?

    Interpreting the Predictive Analytics Forecast

    Let’s look at a typical predictive analytics forecast and see how we might interpret it. We’ll use search volume for “add Google Analytics”, a search with intent. Someone searching for this term is likely attempting to install Google Analytics for the first time; veteran marketers know the process.

    Add Google Analytics search volume

    How do we interpret the graph above? In the version of predictive analytics forecasts I use, I create two charts. The first are actual values, reflecting the range of metrics. This is important to know, because we want to know how much variance there is in a metric. A metric that jumps from 0-100 is a big jump; a metric that jumps from 65 to 66 isn’t.

    The second chart is made of scaled values. These values are the same data as the first chart, but scaled to a 0-100 scale. This helps understand the magnitude of change for narrow variance charts, and also provides a helpful way to index how much change is happening at any one time.

    To interpret the charts, we use the MAISTER cycle framework from Marketing Blue Belt:

    • Measurement: (the chart)
    • Analysis: what happened?
    • Insight: why?
    • Strategy: what’s the big picture goal?
    • Tactics: what should we do?
    • Execution: how will we do it?
    • Review: did it work?

    When we look at the chart above, the first thing that leaps out is that search volume for “add Google Analytics” peaks the week of February 25, 2018. That’s what happened, the analysis. The critical question we need to answer is, why, the insight? What’s special about the last week of February?

    Investigating using tools like Google News, we find that a number of small businesses start at the beginning of the year, and by the time February rolls around, those businesses have finished with the basics of incorporation and are beginning to build out infrastructure – like a website, and therefore implementing Google Analytics.

    What strategy might we build from this insight? If I were managing the marketing for Google Analytics, I’d be sure to design a first quarter campaign initiative around measuring success for small businesses as my strategy, with a goal of increasing adoption of Google Analytics – and convincing businesses to install it sooner rather than later.

    From strategy, we’d identify tactics, from workshops and webinars to Google AdWords and more, all targeted to reach the small business population.

    After tactics, we’d focus on execution. This is where predictive analytics – and its specificity – shines. At a well-run organization, we should know how long it takes us to prepare an ad campaign, a PR campaign, an email marketing campaign, etc. When we know the key dates we must hit in order to take advantage of maximum customer interest, we then build workback schedules.

    In the above example, if we know we must have everything in market by February 25, 2018, and we know it takes 3 weeks for our advertising and creative teams to build an AdWords campaign, we’d need to begin the build process no later than February 4, 2018.

    After we executed the campaign, we’d review it to determine the results. Did we achieve better results in 2018 than we did in 2017?

    Plan and Act

    The most important thing we can do with predictive analytics is to plan and act with our findings. Never let predictive analytics forecasts collect dust. Take action with them, and once we do, we will reap enormous value from them.

  • The Predictive Analytics Process: Predicting

    The Predictive Analytics Process: Predicting 2

    In the last post, we examined different methods for identifying which variable to predict. Once we’ve made a sound, data-driven assessment of what variables matter most to us, we build a predictive model around it.

    The Predictive Analytics Process: Predicting 3

    Predicting Ahead

    To create accurate forecasts, we must use software built for the explicit purpose of time-series prediction. The generally-accepted standard for prediction of time-series data is an algorithm known as S-ARIMA, which is an acronym for Auto-Regressive Integrated Moving Average with Seasonality. Here’s the raw formula:

    arima algorithm

    This isn’t particularly helpful, is it? Let’s dig in briefly into what S-ARIMA does using commute time prediction as an analogy. It’s imperfect (statistically speaking) but useful. Imagine for a moment we want to determine how long it will take to commute to work – a time-based prediction. If we know the distance and the average speed we drive to there, we can predict an Average time to our destination.

    Not all roads are created alike. Some of our roads are small back roads, while others are major highways. To improve the accuracy of our prediction, we might want to calculate a Moving Average, taking into account differing speeds on differing parts of our commute.

    So far, so good. Next, knowing what’s happened already on our drive should impact our prediction. If we just spent the last 20 minutes sitting in a traffic jam, our prediction should take that into account on a continuous basis. This would make it an Auto-Regressive Moving Average.

    Now, suppose we take into account the rate of change. If I’ve gone 5 miles per hour in the last 3 minutes, and I’ve gone 5 miles per hour in the 3 minutes before that, I’m probably stuck in traffic. It’s logical to assume that as long as I’m stuck in traffic, I’m probably going to go 5 miles per hour. Thus, we want to keep an eye on the differences between past moving averages as a way of judging the next reasonable prediction. This is integration, making our prediction an Auto-Regressive Integrated Moving Average.

    I happen to live in the metro Boston area. There’s a big difference in commute time in Boston in February versus July.

    There’s a big difference in commute time during the summer vacation months versus regular months. Our prediction of commute time should incorporate this sort of seasonality into our traffic forecast, creating an Auto-Regressive Integrated Moving Average with Seasonality.

    This analogy helps us deconstruct the S-ARIMA algorithm; it’s a small leap of the imagination to extend it to things like marketing data. We have averages for website traffic, email opens, social media engagements, etc. We can take into account all the seasonality of our businesses, the performance to date, the different methods, etc. and see how S-ARIMA-based predictive analytics applies to our business.

    Prediction Software

    The best predictive analytics software available today comes from the open-source movement. While many vendors offer predictive analytics pre-packaged software for “reassuringly expensive” prices, the reality is that the underlying algorithms are all pretty much the same. The reason why is that much of the research and development in predictive analytics comes out of academia, and thus open-source software is the engine which powers it.

    I recommend picking up either R or Python as the programming languages to develop predictive analytics capabilities, and then look at the many, many predictive analytics packages built for either R or Python such as pandas, timekit, scikit, and many others.

    Making a Prediction

    One of my favorite data sources for predictive analytics is search data. It’s generally well-formed, and unlike other marketing data, search data indicates forward-looking intent. A customer searches for something for intent to purchase in the future.

    Suppose we take search data for a term like “iced coffee”.

    google trends iced coffee

    We know, intuitively, that iced coffee interest is likely higher when it’s warmer and lower when it’s cooler. However, that’s very general prediction. What we’re interested in is specific prediction. When in the future should we plan for iced coffee sales to increase, with specificity?

    Using R and Google Trends data, we project forward the search volume for iced coffee based on the past five years’ data:

    iced coffee predictive analytics forecast

    We now have a specific set of predictions for iced coffee search volume.

    Next: Plan

    As you’ve likely noticed, the prediction itself is not the valuable part of predictive analytics. The real value is in what we do with it, which we’ll cover next. Stay tuned!

  • The Predictive Analytics Process: Picking Variables

    The Predictive Analytics Process- Picking Variables

    In the last post, we examined different ways to prepare data to counteract known, common problems. Let’s turn our eye towards picking which data to predict.

    The Predictive Analytics Process: Picking Variables 4

    Picking Variables

    Picking a variable to predict is a blend of both human insight and machine analysis. The best comparison I know is that of a GPS app. We have lots of choices on our smartphones about which mapping application to use as a GPS, such as Apple Maps, Google Maps, and Waze. All three use different techniques, different algorithms to determine the best way to reach a destination.

    Regardless of which technology we use, we still need to provide the destination. The GPS will route us to our destination, but if we provide none, then it’s just a map with interesting things around us.

    To extend the analogy, we must know the business target we’re modeling. Are we responsible for new lead generation? For eCommerce sales? For happy customers?

    Picking Dependent Variables

    Once we know the business target, the metric of greatest overall importance, we must isolate the contributing dependent variables that potentially feed into it. Any number of marketing attribution tools perform this, from Google Analytics built-in attribution modeling to the random forests technique we described in the previous post.

    As with many statistical methods, attribution provides us with correlations between different variables, and the first rule of statistics – correlation is not causation – applies. How do we test for correlation?

    Testing Dependencies

    Once we’ve determined the dependent variables that show a high correlation to our business outcome, we must construct tests to determine causality. We can approach testing in one of two ways (which are not mutually exclusive – do both!): back-testing and forward-testing.

    Back-Testing

    Back-testing uses all our existing historical data and runs probabilistic models on that data. One of the most common ways to do this is with a technique called Markov chains, a form of machine learning.

    markov chain attribution model

    What this method does is essentially swap in and out variables and data to determine what the impact on the final numbers would be, in the past. Think of it like statistical Jenga – what different combinations of data work and don’t work?

    Forward-Testing

    Forward-testing uses software like Google Optimize and other testing suites to set up test variations on our digital properties. If we believe, for example, that traffic from Twitter is a causative contributor to conversions, testing software would let us optimize that stream of traffic. Increases in the effectiveness of Twitter’s audience would then have follow-on effects to conversions if Twitter’s correlation was also causation. No change in conversions downstream from Twitter would indicate that the correlation doesn’t have obvious causative impact.

    Ready to Predict

    Once we’ve identified not only the business metric but also the most important dependent variable, we are finally ready to run an actual prediction. Stay tuned in the next post as we take the predictive plunge.

  • The Predictive Analytics Process: Preparing Data

    The Predictive Analytics Process- Preparing Data

    In the last post, we examined the basics of extracting data from various data stores and the different types of datasets we have access to. Let’s now look at the process of preparing data.

    The Predictive Analytics Process: Preparing Data 5

    Three Data Challenges

    In the preparation of our data, we typically face three challenges:

    • Missing data
    • Corrupted data
    • Irrelevant data

    To counter these challenges, we should be familiar with three techniques to overcome these challenges:

    • Imputation
    • Anomaly detection
    • Feature engineering

    Let’s dig in.

    Dealing with Missing Data

    Missing data occurs when something goes wrong with our analytics. Perhaps we accidentally deleted a tracking code when migrating software or changing our website. Perhaps a third party omitted the data. Whatever the case may be, we need to deal with the problem.

    First, we quantify how much data is missing. The general rule of thumb among most statistical software package developers is that a dataset becomes unusable when the amount of missing data exceeds 5%. If, for example, we accidentally deleted our Google Analytics tracking code off our website, we would still have mostly usable data as long the total amount of missing data didn’t exceed 18 calendar days per 365 day period.

    Second, if the dataset is still usable, we need to patch the holes in it. In most statistical software packages, libraries exist to help us bridge these gaps. I use R, and the recommended default package for recovering data is called Hmisc. With it, we feed as much data as we have for a time series, and the software attempts to repair it.

    For example, if we have a period of time like 4 days where we messed up our Google Analytics data, we’d use Hmisc and all other data available during that period (like email marketing data, social media data, etc.) to help Hmisc impute the missing data.

    Dealing with Corrupted Data

    Corrupted data occurs when our data goes awry. A simple example is if we installed two copies of our web analytics tracking code on our site. We’d have double the data, but the business results wouldn’t validate the doubling of traffic.

    Corruption in marketing analytics also extends to “black swans”, random, unplanned, and unrepeatable occurrences.

    We detect corrupted data with visualization and anomaly detection. By charting or graphing our data, we identify anomalies. Once identified, we will choose whether to incorporate them into our models or not.

    For example, a couple years ago, I saw a massive one-day spike in my Google Analytics data from a Reddit post that went wild. That post was off-topic from what I write about, but it severely distorted traffic for a day. I choose to simply delete that data when I build predictive analytics models and use the imputation methods above to compensate for it.

    Dealing with Irrelevant Data

    Few things hose predictions (and many statistical methods) like irrelevant data. While missing data can break models and corrupted data can mislead models, irrelevant data makes models completely unusable.

    The antidote to irrelevant data is feature engineering, in which we use extensive testing to determine whether or not a variable is relevant. The most common technique used for variable identification is the random forest, in which our software creates thousands or tens of thousands of simulations using every possible combination of variables, then determines what’s relevant and what’s not.

    Once we identify what’s relevant and what’s not – and good judgement is equally important as machine learning technology – we remove the irrelevant data to improve our model.

    For example, I was doing some analysis of my Google Analytics data and also had social media data alongside it. When I built a random forest of all my variables, virtually all of the social media data – likes, comments, etc. – were irrelevant in terms of what drove business impact. So instead of building a model using all data, I built a model using just the data that mattered most. That in turn changed my social media strategy to focus on one particular set of actions, rather than everything.

    Next: Identify

    Now that we have clean, usable data, we next look at what to predict. Stay tuned!

  • The Predictive Analytics Process: Pulling Data

    The Predictive Analytics Process- Pulling Data

    In the last post, we looked at the consequences of having poor process in our predictive analytics practice. Let’s look at the first step of that process now.

    The Predictive Analytics Process

    Pull

    If data is the new oil, pulling data is analogous to drilling and extracting oil from the ground. We need to identify what data sources we have available to us, understand what condition the data is in and whether it’s suitable for predictive analytics, then move it to processing.

    We have two categories of data we access for prediction: public and private.

    Public Datasets

    Public datasets are important for providing additional context to our data. With public data, we enrich our data with external knowledge that can help explain what we see in our data.

    For example, suppose we’re a coffee shop. We want to predict the number of walk-in customers likely in the next year. It would be helpful to inform our training data – the historical data we build and train our software on – what the weather was like, or what the economy was like at any given point in the past.

    The list of public data sources is gigantic, but some of my favorites for prediction include:

    • Google Trends: a useful source for search data
    • Data.gov: the US government public repository with connections to hundreds of thousands of datasets
    • FRED: The St. Louis Federal Reserve Bank with thousands of time-series datasets on the economy
    • Kaggle: A terrific portal for datasets to learn from
    • Google BigQuery: Google stores massive datasets such as news, books, etc. and makes them available to the public
    • National Weather Service: Meteorological data is available for the entire planet; for the United States, data is available as far back as the late 1700s

    Hundreds more datasets are available and curated by data scientists around the Internet.

    Private Datasets

    Our private datasets are internal data from all our business systems. These private datasets are often what we want to predict. The biggest challenge with most private data is access; as organizations grow larger, access to data becomes siloed within the organization. Only executive sponsorship can keep access to data open, so be sure that’s part of the predictive analytics process.

    The second biggest challenge for many organizations’ private data is data quality. Cleaning up the data or improving its collection is a vital part of preparation for prediction.

    Some of the internal data we most often want to predict includes:

    • Revenues
    • Cash flow
    • Expenses
    • Customer service inquiries
    • Website traffic
    • Lead generation
    • Staffing levels
    • Email marketing performance
    • Ad performance
    • Demand generation

    How to Pull Datasets

    We will most likely need the help of a developer with API experience and a database architect to successfully pull data. The developer will connect to data sources, public and private, and write code that will extract the data on a regular basis for us.

    That data has to go somewhere, so our database architect will help contain the data in a usable format. While many data scientists and machine learning experts love massive database storage systems like Hadoop and Apache Spark, we can make accurate and robust predictions from nearly any database as long as it’s clean and high-performance.

    Next: Prepare

    If data is the new oil, we’ve now got a supply of crude oil. However, crude oil is useless without refining. In the next post, we’ll look at data preparation. Stay tuned.

  • The Predictive Analytics Process: Introduction

    The Predictive Analytics Process- Introduction

    The Predictive Analytics Process: Introduction

    While we understand the value of predictive analytics, the ability to see into the future with specificity and precision, we are often unclear on the process to develop predictions. As a result, our predictive analytics outputs are often incomplete, lacking context, or difficult to understand.

    Introduction: Where Predictive Analytics Goes Wrong

    Predictive analytics often goes wrong in a few – pardon the pun – predictable ways. First, if we attempt to create predictions for things that have never happened before, we will likely fail. My friend and colleague Tom Webster highlights this in attempting to predict events such as elections. If two candidates have never run against each other before, there’s no mathematically or statistically sound way to build a model for the outcome.

    Second, if we attempt to create predictions with poor quality data, our predictions will fail. Predictive analytics is about transforming the general into the specific using statistics and mathematics. The foundation of all predictive analytics is prior existing data; if that data is in terrible condition, it’s as though we are building a home on a rotten foundation.

    Third, if we attempt to create predictions with poorly engineered and refined data, our predictions will fail. Even the best quality data is meaningless if we don’t spend significant amounts of time refining it and selecting exactly what we want – and removing what we don’t.

    Fourth, if we attempt to create predictions with data that is a poor fit for predictive analytics, we will fail. By its very nature, predictive analytics deals with data over time. If we have data that lacks a temporal component, we will not make meaningful predictions.

    Finally, if we attempt to create predictions with no context or explanation, our end product will not move the needle. We will fail to create impact with our models and predictions. In order to maximize the value of predictive analytics, we must build so that business users find immediate and long-term value in them.

    Solving Problems

    If we have no process for predictive analytics, any of these problems are not only possible, but likely. Solving these problems is a matter of establishing a clear process for predictive analytics.

    The Predictive Analytics Process: Introduction 6

    In this series, we’ll look at the five-step framework for developing predictions from our data. By following this process, we will be much more likely to create impact with predictive analytics.

  • First Steps Towards Thinking About Automation in Marketing

    First Steps Towards Thinking About Automation in Marketing

    For many of us in marketing technology, a “one-off” task quickly becomes a standard, and if that one-off task is labor-intensive, we end up creating a lot of work for ourselves. How do we avoid creating unnecessary work? The answer lies in a mindset change, from “how do I do this?” to “how can this be automated”? After all, if it’s valuable, someone will likely ask us to do it again. Thinking like a machine – algorithmically – helps us design and build marketing that scales.

    This is the mindset of the folks who work at companies like Google, folks who focus on algorithmic solutions to problems rather than single-instance uses of people’s time. Every process they automate permits them more free time as well as greater scale.

    If we don’t have a background in programming, development, or high tech, how do we cultivate this mindset?

    Is There An App For That?

    The easiest trick is one that’s often a joke punchline in tech circles, but can legitimately begin to alter our thinking towards an automation mindset. Every time we face a repetitive task, ask if there’s an app for that. For example, I was going to sync up some folders on my Mac. Is there an app for that? There is – it’s actually built into the Mac, a command-line app called rsync. Typing rsync -rtv /sourcedirectory /targetdirectory at the command line (obviously substituting your own directories where indicated) will sync up two folders.

    By starting to think of problem solutions in the context of pre-built apps that could solve our problem, we change our thinking from one of labor (how do I do that) to one of automation (someone must have written a piece of software to do that). That begins to make processes more repeatable, more scalable, and more reliable. In the example above, I would no longer need to waste my time or someone else’s time making sure two folders had the same contents. I’d just run that little program as often as needed.

    Eventually, we’ll learn to start copying and pasting little scripts and programs from sites like Stack Overflow, Stack Exchange, and Github. In turn, we will begin to adapt other people’s code to suit our needs, and one day evolve into writing our own code. While it won’t happen overnight, it will happen if we’re diligent about continuing to ask if there’s an app for every repetitive task we face.

    Some things don’t have apps. Some things shouldn’t have apps. But for the majority of repetitive tasks, asking if there’s an app for that is our first step towards building more scalable marketing. With scale comes greater impact, more free time, and more results generated. Start asking if there’s an app for that today.
