Personal Banking and the Data-Driven Approach reported recently on a phenomenon they characterized as “The Downside of the Data Driven Decision.” The LA Times first uncovered Wells Fargo’s quota of eight consumer products per account. The story described questionable tactics used by bank employees to meet that goal. American Banker quickly picked up on the…

The difference between analyticbridge and DataScienceCentral?

I'm wondering the difference between these two sites.

Why should I follow one instead of another?

Sometimes I see that would be better if the two websites were joined.

Article: Using Data Mining to Predict the Winter Olympics Medal Counts

Could data mining techniques accurately predict the medal counts at the Olympics?  This question came into mind four years ago while watching the Winter Games in Vancouver.  I knew that a predictive model could give us an estimate of the number of medals each nation might win; but how close could we get to the actual outcomes? It was a tantalizing project ….          …

Pitfall of "regression to the mean" in growth hacking

These days people seem to believe that "growth hacking" must be immediate and rapid. Partly it's true; but I'm afraid partly it's not, because iterative short-term and intensive growth hacking may fall into a pitfall of "regression to the mean".

This post is a translation from the Japanese-version of my blog, but I believe this point of view…

Why Companies can't find analytic talent

I'll add another reason why companies can't find analytic talent: their recruiting practices are simply awful.  They drag out the due diligence process far longer than necessary; they keep candidates in the dark about where they stand; and they request many more meetings and phone calls than are necessary.  I've also heard more than a few stories about hiring managers going through the process and selecting a candidate to make an offer to, and then the hiring manager's boss or the CFO…

Big Data and Data Science Books - A Baker's Dozen

Here are 13 informative and inspirational books on Big Data and Data Science.  This is definitely not intended to be a comprehensive list (since a complete list of such readings would itself be a form of "Big Data", and consequently the number of possibilities is a nearly uncountable number! NOTE definition of "uncountable" = an infinite set that contains too many elements to be countable.)…

Will The Buy The Dip Mentality Work In 2014?

Let's face it, in 2013 almost every dip in the major stock indexes turned out to be a buying opportunity. Every time the stock market seemed to be starting a correction or meaningful pullback the central bankers came running out on TV proclaiming that low interest rates would remain intact for years to come. Just think about it, there has not been a single 10.0 percent correction in over two years. The last time the stock market even came close to a real correction in 2013 was in May…

Social Media: how to measure their impact?


For a company, having "a presence" in social media is worthless unless it allows it to achieve some objectives. However, beyond the control of the company, social media talk about the company, under these conditions is it reasonable to ignore this space frequented by customers, prospects, partners and competitors?

Comparing machine learning classifiers based on their hyperplanes, for "package-users"

In English-version of my personal blog, I posted an article about how we should understand a nature of each machine learning classifier; my solution is "just looking at a hyperplane of each".
