Is BI Technology Too Sexy?

Interesting premise from Peter O'Donnel that BI software vendors are incorrectly selling "the cult of the new".

Happy Independence Day India!

The road to independence was hard but worthy
The road of a free nation is hard but worthy
The people of India known the meaning of hardship and worthiness
I am privileged to have them as my friends
Happy Independence Day India!

New Media Quizzes, Surveys, and Games: Business Analytics Opportunities

If you are in Facebook you have seen a large number of friends take quizzes, surveys, and play games. What the implications of the use of these gadgets in the area of business analytics? The implication is a new wave of opportunities by leveraging the information gathered from these gadgets to increase revenues and profits, and reduce costs. These gadgets may be silly but they contain a troll of information.
1. Advertisers can use segmentation to create robust profiles of customers. Also, they can use cross-products predictive modeling, and spatial (geographical) benchmarking.
2. Marketers can use CTR (Click-thru-Rate) outlier analysis, GRP (Gross Ratings Points) time-series, and TRP (Targeted Rating Points) predictive modeling.
3. Social Media companies can use log-on outlier (to make capacity planning decisions). Also, they can do contribution (users that contribute) segmentation, and use time-series to determine time spend online.
4. Gaming companies can predict revenues by using predictive modeling, and outlier analysis to detect fraud and abuse. Also, they can control inflation using virtual economy tools.
5. Online customer service can do TPC (Time-per-Call) outlier analysis, and segmentation to create profiles based on average cost. Also, they can use predictive modeling to predict and control costs.
6. Blogging sites can use statistical control process to determine best practices in customer reach, as well as predictive modeling. Also, they can create strong branding variables.
The above-mentioned analytics combined with a powerful 3D visualization allows new media companies to increase their ROI. My advice to new media companies is if you want to increase profitability you must use advanced analytics techniques to analyze information on quizzes, surveys, and games.

Researchers mine millions of metaphors through computer-based techniques

This technique developed at Stanford University is going to revolutionized text searching. The 'proximity-searching machine-learning" technique have potential applications in CRM databases for financial services, retail, and CPG. Even more interesting is to use this technique for clinical research using patient records in order to link symptoms, diagnoses, and treatment. Also, it has uses for government intelligence gathering.

Detecting the Madoff Effect: Methodology for Fraud in Hedge Funds

As a result of the recent Bernard Madoff fraud scheme, pension funds and corporate finance managers have been put on the defensive, wondering how to detect this type of “under the radar” deceptive scam. The depth of the fraud in the case of Bernard Madoff and his ability to engage in a $50 billion undetected scheme employing “serial correlation” demonstrated the vulnerability of financial institutions to trusted individuals operating inside the security model. Bernard L. Madoff Investment Securities LLC (“Madoff”) engaged in a ponzi or pyramid fraudulent scheme in which investors were paid interests not from actual investments but from the funds deposited by other investors. But being on the defensive is not the ideal solution, as it forces financial institutions into a reactive mode, always trying to catch-up with the perpetrators, who somehow remain one step ahead. We would like to suggest a more proactive approach and corresponding methodology for detecting fraud in hedge funds.

Madoff was able to hide his scheme using a “serial correlation” reporting scheme. A serial correlation is a term used by MIT professor and hedge fund theorist Andrew Lo to describe the degree to which each month's returns in a fund mirror the results of the month before. Dr. Lo’s theory is that is a hedge fund has a nice smooth line in its rate of return every month. Upon close examination, any variation to the “smoothness” of the line constitutes a red flag, which should be look upon more carefully.

In the last year corporate finance departments, financial institutions, as well as public and private pension fund portfolios have already lost about 33% of their values due to overleveraged investment banks, the housing and credit crises. An effective, (no more than 1 to 3 weeks) and cost efficient proactive methodology to detect the Madoff effect in the hedge funds would be to apply the following methodology in the specified order to the relevant data available to you:

• Link Analysis – Use link analysis to determine in the network Madoff is categorized by, and create a subset of that network of hedge funds.
• Predictive Modeling – Use predictive modeling to create a score of all the hedge funds in your subset. Use Madoff’s variables as your training data.
• Clustering Analysis – Perform a cluster analysis which includes among other variables the predictive score. Since the predictive score is a multidimensional variable when used with one-dimensional or “flat” variables you will obtain a binocular vision (or binocular summation) of your analysis and increase by 1.4 times the ability to detect the serial correlation. See, Improving Search Engine Optimization by Incorporating Predictive Analytics at http://atomai.blogspot.com/2008/12/improving-search-engine-optimization-by.html
  
  For verification of the analysis you could use the following factors:
• The reputation of the independent auditors of the hedge fund identified through this methodology;
• Control Chart using standard deviation of the yearly returns over a 3-5 year period (exclude the current year);
• The ratio of total number of employees to the total amount of investments.

Improving Search Engine Optimization by Incorporating Predictive Analytics

As more companies increase the size of their databases search engine optimization (SEO) techniques can be adapted to data mining of commercial databases. In SEO link analysis is a measure of the quality and relevance of the set of links pointing to a given site. This is measured is achieved through an algorithm that maps the hyperlinks in a series of networks. The measurement creates a ranking of the strength of the inbound links to a particular network. The objective of link analysis is to detect patterns or trends that would make the search engine to bring to the top the most relevant web sites in any search.

Link analysis contains multiple variables that are analyzed. Google’s claims over 200 variables are analyzed in its link analysis for its ranking algorithm. Although I do not know which variables it uses, I surmise that they are the keystone of Google’s success. The core of any analysis is its variables. Let me suggest the utilization of predictive modeling as an additional variable that will improve SEO.

Using predictive modeling as another variable in link analysis could potentially increase SEO by 1.4 times by giving depth perception to the link analysis. In ophthalmology medicine it an established fact that binocular vision gives depth perception, and that depth perception (or binocular vision) increases the range of view 1.4 times greater than monocular vision. In other words, you can see better with two eyes than with one eye. The equivalent of depth perception in analytics is the addition of a predictive modeling (or scoring) variable to any pattern detection analysis.

A predictive modeling variable will improve the SEO because:

1. It gives an independent variable that acts as a spare variable in case that another variable is not working. In other words, you can use a predictive modeling variable in a correlation analysis as your independent variable against the other numerical variables in your link analysis.
2. A predictive modeling variable will widen the field of view of your networks from 160 degrees to 200 degrees.
3. Binocular summation (seeing with two eyes) will enhance faint but important networks and links within your data.

Among SEO scientists, statisticians, and business analysts it would increase stereopsis, or the keen sense that they have depth perception. In other words, it would give them another tool to do their work more efficiently.


Most of the variables used in link analysis are flat, or with one-dimension. A predictive modeling variable is multidimensional and hence a “depth variable”. The addition of a “depth variable” to any analysis statistically can be expressed as detecting the networks using two sensors instead of one. If each flat variable alone had a 0.6 probability of detecting a network, that probability has been calculated to be:

Pb = Pr + Pl - (Pr x Pl) = 0.6 + 0.6 - (0.6 x 0.6 ) = 0.84 (1)

The improvement from 0.6 to 0.84 represents a 1.4 fold improvement. This improvement can be achieved in any analytics technique by adding a multidimensional variable to a one- dimensional variable during analysis.
