Title: Dimensionality Reduction: Neural and Neuro-Fuzzy Frameworks

Abstract:Successful design of any “intelligent system” demands use of an appropriate set of features. Ideally a useful set of features should select necessary features, discard derogatory features and indifferent features, and it should have a controlled level of redundancy. Complete elimination of redundancy is not desirable as then the system may not be able to tolerate any measurement error. The feature selection problem can be generalized to sensor selection where a sensor is responsible for a set of features. In this talk, first we shall discuss how neural networks can be effectively used for structure-preserving dimensionality reduction. This approach does not use class labels and since it preserves the “inherent structure” in the high dimensional data, it is quite effective for most applications, in particular, for data visualization. This will be followed by how neural networks and neuro-fuzzy systems can be adapted to select useful features discarding derogatory and indifferent features. The neural model will then be enhanced to deal with the problem of sensor selection. Finally, we shall present how the neural networks can select features (as well as sensors) with a control on the level of redundancy in the set of selected features (sensors).
