Mark Twain famously said “There are three kinds of lies: lies, damned lies, and statistics.” Maybe if Mark Twain were alive today, he’d add “alternative facts” to that list. BusinessWeek in the article “Lies, Damn Lies, and Financial Statistics” reminds us of the management challenges with statisticians or “data scientists” who manipulate the…

Let’s be honest, today “big data” is sort of a dirty word in the public consciousness. It is associated closely with profit maximization techniques (such as recommendation lists on e-commerce sites and targeted ads), high-profile data leaks and privacy issues.
People do not like being a bundle of unsecured big data tied to a bank account. They want to be unique. Yet… Continue

This is our second post of a new series featuring articles published long ago. We manually selected articles that were most popular or overlooked, time-insensitive (for instance we eliminated articles about data science products because software packages and platforms have evolved so much over the last few years) and we only kept articles that still make sense and are useful today. Our previous edition… Continue

Every product team wants to know what makes their product thrive. They want to know how to optimize metrics and leave users the happiest and most engaged. Without a way to definitively understand user behavior, they must turn to anything they can. Enter the A/B test.
Ultimately, every A/B test starts from a hypothesis. The hypothesis could be, “If we did [blank], then we would improve conversion.” Or “Feature X should drive increased retention, let’s test out that assumption through… Continue

Summary: This is a lesson in how it may be possible to snatch victory from the jaws of defeat. 1.) A good ROC score does not necessarily mean a good model. 2.) Even a weak model may be good at the top and bottom – consider how you can use that.
This is a lesson in how it may be possible to snatch victory from the jaws of defeat. In our world, defeat is ending up with a poor model that doesn’t do what you’d hoped. This story about a particular project… Continue

Past literature show that the comparisons of classifier's performance are specific to the types of datasets (e.g., Pharmaceutical industry data) used; i.e., some classifiers may perform better in some context than others. A paper titled CDS Rate Construction Methods by Machine Learning Techniques conducts the performance comparison exclusively in the context of financial market by applying a wide range of classifiers to provide solution to so-called Shortage of… Continue

General Motors’ decision to stop selling the cars in India, is a major step towards “creating a forgotten “image of brand Chevrolet sooner than later. This is a potential indication of shaken belief system from global manufacturer and an engineering company.
This decision compels one to think on what could be possible causes, this is for sure not the failure of long term strategy nor intellect of teams working towards creating brands, selling cars, and generating revenues.

Analytics is the most sought after competency in the business world right now. LinkedIn identified it as one of the most wanted skills across the globe. I have had discussions with various L&D heads who say the mandate this year is to build analytics talent within their organization. Over the course of many such discussions, I realized that while the end goal is clear for such organizations, the path is often not.
Analytics is very simply defined as the ‘language of data’. When we… Continue

Prevailing AI technology for analytics prefer the use of statistical science as the foundation for machine learning (ML) on historical data to distill knowledge and experience. Whether it be supervised or unsupervised, the result is then incorporated into playback engines to analyze new data. These methods and procedures work well for predictable scenarios with known outcomes and known variables.
What if the variables are unknown, and… Continue
