Abstract

The paper presents a novel generic method for on-line feature extraction from an incrementally trained connectionist system. The method is applied on a case study problem of identifying genes related to classes of diseases, in particular - 14 types of cancer. The method is based on the evolving connectionist systems ECOS paradigm. The analysis of the discovered features through the application of the proposed method on the case study data, demonstrates the potential of the method for solving important real world problems, such as the problem of defining genes related to diseases.
