The Smart Grid, Predictive Analytics, and Cloud Computing

With the advent of smart meters and sensors, the Smart Grid is becoming more and more part of our daily life. In the past, we would only realize how important energy was when the lights went off, in the future, we will be able to adjust our behavior to utilize energy in a smarter, more efficiently and less costly… Continue

Ads That Reject The Click

By Kyle Johnson



Is online advertising a good vehicle for reaching brand advertising goals? Judged by their actions, more and more advertisers are voting “yes.” During the past several months, we’ve observed a gradual but decisive stride from an ambivalent stance toward a full embrace of online media as a branding tool.



This past week, we witnessed a Ford display campaign that to us represented a noteworthy waypoint in the development of online ads designed for branding… Continue

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

Mercury News

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

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

New iPhone app "Outbreaks Near Me" locates H1N1 (swine flu), infectious diseases

See article below. I have 2 questions:



  • Privacy issues - risks of being quarantined for reporting contamination by infectious disease. Can you report anonymously? How can a user trust that her report is anonymous?
  • Fraud and errors - people reporting wrong information (on purpose or not). After all, the average citizen is not an expert in infectious diseases.
These issues can be handled (that's my domain of expertize), but I am wondering if and how these… Continue

American Recovery Act Business Intelligence: What are the Implications for the BI Community?

The American Recovery Act Business Intelligence mandates detailed reporting at the enterprise level, about how the government money was spent. It also forces grant beneficiaries to provide accurate lift measurements accomplished thanks to the recovery funds.



While many companies already perform this type of auditing using various BI platforms, e.g. to provide accurate core financial and non-financial summary statistics to Wall Street, the Recovery Act enacted last February should… Continue

Gaussian copula function: The Formula That Killed Wall Street

From the Wired Magazine (Felix Salmon)



A year ago, it was hardly unthinkable that a math wizard like David X. Li might someday earn a Nobel Prize. After all, financial economists—even Wall Street quants—have received the Nobel in economics before, and Li's work on measuring risk has had more impact, more quickly, than previous Nobel Prize-winning contributions to the field. Today, though, as dazed bankers, politicians, regulators, and investors survey the wreckage of the biggest… Continue

Hidden Decision Trees - A Better Approach to Scoring

Hidden Decision Trees is a statistical and data mining methodology (just like logistic regression, SVM, neural networks or decision trees) to handle problems with large amounts of data, non-linearities and strongly correlated independent variables.



The technique is easy to implement in any programming language. It is more robust than decision trees or logistic regression. Implementations typically rely heavily on large, granular hash tables.



No decision tree is… Continue

Legislation Aims To Curb Data Mining

Most people are unaware that after they fill a prescription, many pharmacies turn around and sell information about that prescription to pharmaceutical companies in order for them to market their drugs to physicians. This practice is called data mining and it has negative consequences for the public health, health care costs, and privacy.



Through data mining, pharmaceutical companies are able to target-market their high-cost, brand-name drugs to prescribers who either are already… Continue
