Power Real Polynomial to approximate functions: The Gradient Method

In the real world rarely a problem can be solved using just a single algorithm, more often a solution is a chain of algorithms where the output of the former is the input for the follower.

But you know that quite often machine learning algorithms return functions almost always extremely complex, and they don’t fit directly in the next step of your strategy.
In these conditions, it is really helpful the trick of the function approximation, that is, we reduce the complexity…

Leveraging Visual Analysis to Detect Medical Fraud

Discovering fraudulent trends and patterns within medical data is the modern day equivalent of finding a needle in a haystack. Private medical and property/causality insurers as well as government agencies are tasked with discovering and preventing medical fraud from within millions of submitted bills daily.

How to Lie with Statistics | Investopedia.

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…

Has Analyticbridge been attacked by remote terrorists?

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…

Are Lottery Winning Numbers Really Random?

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. …
