Evolution of every species on the planet has happened through a series of experiments – each experiment done with just one objective – to survive and to improve the chances of survival of the next generation. The selection criteria was simple – if the experiment succeeds, you survive and get to pass on your genes. If the experiment fails, you die!
The same instinct for arriving at innovative solutions can be applied to solving business challenges too – Of course the…

By Brian Bloch | Investopedia – Fri, Nov 25.
It is no secret that various people or bodies within the financial services industry will say or write whatever will sell the products, rather than what is actually true and correct. For this reason, buyers may be more inclined to rely on what they think is hard evidence – in the form of statistics and charts. Regrettably, one…Continue

We've experienced a number of small Internet problems that were easily fixed, just before Thanksgiving. But there was one attack that looked very weird, and the motivation behind this failed plot is obscure. Most likely, our publication of new material to better and automatically detect scammers on social networks probably triggered the retaliation. We've experienced this type of retaliation in the past, when…Continue

(Reuters) - Exchange operator CME Group Inc (NasdaqGS:CME) fined Infinium Capital Management, a U.S. high-frequency trading firm, a total of $850,000 for three separate computer malfunctions that rattled futures markets in 2009 and 2010.

In particular, do casinos use statisticians to detect well disguised schemes? For instance, what about clients that spend a lot of time and money in online casinos, and on average win 53% of the time (odds should be below 50% if you participate in a large number of games)? Or those who lose most of the time but usually win big when they win? …Continue

In this recent editorial about the Occupy Wall Street movement, Richard Kim profiles a protestor that despite having a master’s degree can’t find a job. This particular protestor quit his job as a school teacher three years ago and took out a $35K student loan to obtain a master’s degree in puppetry from the University of Connecticut. I…Continue
Most analytic people would agree that lottery is a tax on the innumerate. However, for this statement to be true, we need to assume that winning numbers (and any combination of digits from these numbers) are truly random. If not, of course smart people are going to find and devise algorithms to increase their odds of winning, and/or will try to sell their magic "winning numbers" to idiots. …Continue

And to feed billions more humans! There has been lots of research and development to improve farming over the last 6,000 years. This includes irrigation, crop rotation, fertilizers, insecticides, genetic engineering, building skycrapers where vegatables are grown on each floor, etc.…

The recent attack on Facebook (with almost a billion users exposed to porn and violence spread by spammers), as well as the unreported / undetected attack on Yahoo Finance - with thousands of fake members posting comments against "Occupy Wall Street" (where 5 days ago thousands of possibly fake posters were posting comments in favor of this movement) raise questions about the business value of hiring data scientists, based on the…Continue
We tested how Google and Bing are vulnerable to sophisticated algorithmic attacks that could potentially erase all paid ads and organic search results on search engines.

I have been working on this (mostly) annotated collection of tools and articles that I believe would be of help to both the data dabbler and professional. If you are a data…Continue
There was a recent article in CFO Magazine that discussed the possibility of adding talent to the balance sheet. Thinking of talent as organizational assets - not just lip service from the CEO that "employees are our greatest asset"- means collecting quantified talent analytics - data that directly measures how employees work and what they care about and then use this data in conjunction with core business…Continue

There's apparently a shortage of analytic talent to fill these new "yield optimization scientist" and similar positions created by ad agencies. Since I get lots of resume each week from stellar, perfectly qualified candidates who want their resume posted on DataShaping, and few if any request from hiring managers looking to fill these positions, I think that
