The Las Vegas Counterfeiting Story: Is Your Privacy Worth More Than a Poker Chip?

By Ray Everett-Church

Last week in Las Vegas, a husband and wife team were indicted for putting $60,000 in counterfeit $100 bills into slot machines at Caesar’s Palace.

Apparently the fake bills were of such high quality that the bill scanners on the slot machines accepted about 600 of the bogus Benjamins over the course of four days before the money laundering plot was uncovered.

But what makes this story interesting from a privacy and security perspective is… Continue

Fabio Mercurio of Bloomberg & Iason ltd., and

Paola Mosconi of Iason ltd.

June 1, 2009

Abstract: We extend the model presented in Bonollo et al. [3] by introducing a multi-scenario framework that allows for a richer and more realistic specification, including non-static (stochastic) probabilities of default and losses given default. Though more complex from a computational point of view, the model with scenarios is still… Continue

Net Lift modelling

One of the most perplexing data mining dilemmas has to do with building tools that effectively rank order net lift. Essentially, marketers will promote a group but also have a holdout group where there is no marketing treatment. The modelling dilemma is that the net lift or difference in response rate between the marketted group vs. non marketted group is the same across all the deciles when models are typically built against the marketted group. There is software offered by some vendors that… Continue

Everyone knows the flip of a coin is a 50-50 proposition.

Only it's not.

You can beat the odds.

So says a three-person team of Stanford and UC-Santa Cruz researchers. They produced a provocative study that turns conventional wisdom, well, on its head for anyone who has ever settled a minor dispute with a simple coin toss.

It also could have… Continue

#24: Here's a thought...

An occasional series in which a review of recent posts on SmartData Collective reveals the following nuggets:

This or that?

By and large, I think marketers and market researchers underestimate the fundamental role of comparison and contrast in the way we make judgments about products. As Professor Tripsas makes clear, humans (consumers included) rely on categorization to understand the world. Looking at a new, discontinuous product, we’re likely to ask, is it this… Continue

Marketers need new models..customer behaviour is changing!

For Marketer’s any change in customer behaviour is a “gold mine”. Marketing to customer’s whose behaviour is changing is far more rewarding than marketing to “static” customers! But sometimes there is "too much change" and in today's market that is exactly what is happening. Marketer's need ,what we at Cequity, call a Modelling factory approach-How to build models at speed!

Gallup chief economist Dennis Jacobe concurs that "a fundamental change is taking place" in the behavior of… Continue

A Better Way to Mine Data

The good news, for marketers, is that data mining really can make a difference to most bottom lines. The bad news is that, despite what data mining can do, it is so often used so poorly that it is virtually useless.

In many cases, the data is a big part of the problem. Even in the most reputable companies, data is often “dirty,”—out of date or otherwise irrelevant. Most commercially available data mining packages lack the flexibility and functionality that real world marketers need.… Continue

Hamburger Data Quality- data collection is the start

Author: James Standen

I have noticed that when I go to a fast food outlet no matter what I get to drink with my meal it is almost always listed as "Cola" on the receipt. But I didn't order Cola. Ever. Usually I get juice, or milk. So every time I order a burger, I'm clearly a source of bad quality data.

I have looked over the counter on many occasions while I was waiting for my burger and watched the server key in other peoples orders; their fingers flew accross the… Continue

Netflix Prize Pioneer to Speak at Predictive Analytics World

The Netflix Prize competition attracted a well-earned, white-hot spotlight in recent years, awarding a $1,000,000 prize last month for advancement in product recommendations systems - the prediction of each consumer's movie ratings.

Interview with Direct Response Specialist (DRS) and Social Media Executive (SME)

DRS: Well this is not even a fair debate. When providing free content, how are you supposed to track sales leads? How do know who is downloading your free papers, reports or whatever? Don’t you know that one of the most valuable tools a company can have is their database of current and potential customers? Free content, well that is just plain… Continue

The need for cultural transparency

So if CEOs are starting to embrace social concepts for their businesses, then that means the leadership model is starting to change in these organizations... or at least it's starting to get very stressed. At the core of this change, though, is the concept of transparency. The software that enables social business has inherent… Continue
