Data Mining, Neural Networks and Rule Extraction; IEEE CI Distinguish Lecture

Abstract

This lecture was held during the IEEE SCG CI Chapter meeting. The lecture was open to all members of IEEE. This event is sponsored by Computational Intelligence Society under its Distinguished Lecturer Program. SUMMARY: The opening part of the talk introduces basic premises of data mining. It is shown how numerous paradigms of neurocomputing that are data-driven modeling, feature extraction, dimensionality reduction, visualization, knowledge extraction and logic rule discovery prove useful and effective for data mining. Such modeling, however, often involves handling of heterogenous, subjective, imprecise and noisy data. The second part of the presentation outlines the concept of dimensionality reduction of input data vectors. This technique leads to reduced models achieved through evaluation of sensitivity matrices of perceptron networks. When developing reduced models it is also useful to eliminate underutilized internal weights and also neurons via pruning techniques. The concluding part of the talk reviews the capabilities of perceptron networks for producing understandable IF-THEN rules. Logic rule extraction via neural networks evaluation is discussed and illustrated with examples. SPEAKER: Dr. Jacek M. Zurada is the S.T.
