Abstract

This paper reviews and analyzes the performance of the TaSe-II model, carrying out a statistical comparison among different TSK fuzzy system configurations for function approximation. The TaSe-II model, using a special type of rule antecedents, utilizes the Taylor Series Expansion of a function around a point to provide interpretability to the local models in a TSK approximator using a low number of rules. Here we will review the TaSe model basics and endow it with a full learning algorithm for function approximation from a set of I/O data points. Finally we present an ANOVA analysis about the modification of the different blocks that intervene in a TSK fuzzy model whose results support the use of the TaSe-II model.
