Reliable and fast data mining using statistical networks

By Ashutosh V. Deshmukh

Data mining is a growing field driven primarily by the database explosion and availability of powerful computers. Data mining discovers relationships, patterns, trends and predictive information from large and complex databases. Generally, data mining is data driven, not user driven or verification driven [1]. Users do not form and test hypotheses; data mining tools discover previously unknown relationships by working bottom-up on the data set. Data mining provides a convenient way to extract information from large databases generated by corporations and other entities, and has been successfully employed by many businesses.

Data mining tools use different types of processing algorithms. The four primary methods are associations, clustering, classification and sequential patterns [2]. These methods can be further grouped; for example, classification can be achieved by decision trees, rule discovery, neural networks, rough sets, etc. The Internet lists numerous companies producing "siftware" (software to sift through databases) using the above approaches [3].


Introduction to ModelQuest Expert
ModelQuest Expert (MQ Expert) is one data mining tool among a family of PC-based data mining tools (MQ MarketMiner and MQ Enterprise) developed by AbTech Corporation. MQ MarketMiner (currently in Beta) and MQ Enterprise are client/server applications that run on Windows NT and select UNIX platforms. They differ primarily by their ability to handle the number of variables, size of data and also their reports and analyses. The details of these products are available on the company's web site. MQ Expert is AbTech's stand-alone product capable of handling 100 variables and 32,000 examples. MQ Expert uses a unique approach to data mining employing multiple strategies.

Product Information The processing algorithms, utilized by MQ Expert, are based on concepts drawn from statistics, neural networks, and expert systems. By integrating these concepts AbTech has developed proprietary statistical networks, which are at the heart of the data processing algorithms in MQ Expert. Statistical networks are similar to neural networks, however, the nodes in the statistical network represent mathematical functions. Each node accepts a set of inputs and, using mathematical functions, calculates the output.
ModelQuest Expert 1.0 is distributed by AbTech Corporation, 1575 State Farm Boulevard, Charlottesville, VA 22911.
