Pointers for Applying Machine Learning to Business Problems 1– Begin with a priority problem, not a toy problem
In an off-mic conversation with Dr. Charles Martin (AI consultant in the Bay Area), he mentioned that many companies read about ML with enthusiasm and decide to “find some way to use it.” This leads to teams without the real motivation or gusto (or committed resources) to drive an actual result. Pick a business problem that matters immensely, and seems to have a high likelihood of being solved
UBER’s Danny Lange has mentioned from stage that there is one thought process that’s highly likely to yield fruitful machine learning use case ideas: “If we only knew ____.”
Ask yourself, what mission-critical business information are you dying to know, but can’t currently access? Maybe it’s understanding the lead sources most likely to yield the highest customer lifetime value, or the user behavior most indicative of expected churn.2- You can give it data, but all of the context must come from you
Thinking through what information to “feed” your algorithm is not as easy as one might presume. While ML algorithms are adept in identifying correlations, they won’t understand the facts surrounding the data that might make it relevant or irrelevant. Here are some examples of how “context” could get in the way of developing an effective ML solution:
Building an ML solution requires careful thinking and testing in selecting algorithms, selecting data, cleaning data, and testing in a live environment. There are no “out-of-the-box” machine learning solutions for unique and complex business use cases. Even for extremely common use cases (recommendation engines, predicting customer churn), each application will vary widely and require iteration and adjustment. If a company goes into an ML project without resources committed to an extended period of tinkering, it may never achieve a useful result.Quotes from the TechEmergence Network:
We again reached out to our network of TechEmergence interviewees and consensus respondents for opinions and tips on implementing machine learning in business. Below are a collection of quotes:
Dr. Ben Waber — PhD, MIT; CEO of Humanyze (AI-powered people analytics company)
“You cannot use ML to solve business problems in a vacuum. Make sure you get buy-in from business unit leaders to make concrete changes based on the analysis.”
Dr. Danko Nikolic — PhD, University of Oklahoma; Data Science and BD&A, Computer Sciences Corporation
“The most common mistake that businesses make when using ML is that they think that an ML solution is a one-shot process: They send data to data scientists, and data scientists send back THE model. In contrast to that, finding a good ML solution is an iterative process that involves research, trials, and errors, experimenting, talking to the business experts, etc.
ML cannot ever become a commodity. The success of ML depends strongly on the knowledge, skills, and dedication of the people who do it.”
Dr. Charles Martin — PhD, University of Chicago; CEO, Calculation Consulting
“Avoid setting up massive infrastructure until you have a handle on what you want to do. You can easily spend 6 months to a year setting up Hadoop and Spark and not see any ROI.
You will be lucky if 5% of your data is correct and useful. You need to design an experiment that can identify the low hanging fruit and ferret out the data you need. You can build an algorithm on a high memory AWS node.
Get the algorithm into a live environment and test it as early as you can. Don’t build try full production system. Remember, ML is about math, not coding! You want to test it small. Run enough examples to flush out the problems, but not so small that the statistics are meaningless.”
Ferris Jumah — Previously ML at LinkedIn; Bay Area ML Consultant
“Get data driven as soon as possible. Machine Learning doesn’t come for free. You need to build intuition around your data, how you measure the business and know your customers, link not just measurements but also insights to decision making. Log everything, build storage and processing systems, ensure they are accessible, conduct deep analysis and as many experiments as you can on your product, build in intelligence into as much as your product as possible.
At this point, consumers expect personalization and “smart” features. Build them in, learn from them, and ensure that you have a feedback mechanism in place. Finally, hire and invest in data people who are passionate about your problem and business.”
The consensus (in the limited number of quotes above, and from dozens of other conversations with business-minded data scientists) is that machine learning is not as much of a mere “tool” as, say, marketing automation software. Anyone with a good manager and a bachelors degree from a community college can pick up Constant Contact or even (with a bit of tinkering and calling the support line) Marketo or Hubspot and drive some company value.
There are no simple shortcuts to iterative, multi-faceted process of applying machine learning. image credit Microsoft’s CortanaIntelligence.
ML doesn’t yet show up in a neat box, and value is wrought by hard thinking, experimental design and – in some cases – hard mathematics. A little bit of time on Google and YouTube, and you can get a hang of how to set up DropBox for your business. Predicting churn rate across your customer segments with machine learning? Not the same game.
Preparing to derive business value from ML implies having trained talent, expert guidance, and an (often) tremendous “data cleansing” period – and none of it is guaranteed to be a win, as Dr. Martin states aptly above. If Google, Amazon, and Facebook could get their interns to set up ML systems, would they really be spending millions and millions of dollars to scoop the world’s top AI talent out of academics to work for them?
While machine learning isn’t an easy setup, it’s also not one that any future-minded business can leave off the table for too long. The efficiencies gained by the “rockstar” tech companies through machine learning are substantial, and startups here in the Bay Area aren’t just getting funded because “machine learning” is a buzzword. It’s also because many of them have a powerful and strong business case.
Interested readers might benefit from our recent consensus of 26 machine learning / AI researchers where we asked: “Where should machine learning be applied first in business?” The infographic featured drives home many of the same points highlighted in this article.
The ultimate question for executives remains: When can we have (a) the resources required to invest in machine learning seriously, and (b) a legitimate use case that started from trying to find real business value, not from “trying to find a way to kinda use machine learning.” That’s a thought process that can’t be done for you, but our hope is this article has helped to inform your perspective and give you resources to draw from in future.
