Building Parsimonious Systems from Data: Computational Intelligence Approaches
Abstract

I begin with two quotes: "Make everything as simple as possible, but not simpler:'(Albert Einstein) "The principle of parsimony is valid esthetically in that the artist must not go beyond what is needed for his purpose:'(Rudolf Arnheim) These quotes were not written for designing of decision-making systems from data. But they implicitly, at least in my view, suggest a great principle of designing systems from data. When we design a system we should not go (use) beyond what is needed to solve the problem. They advocate fo「parsimonious systems, which should use just "adequate" inputs (adequate information) and should not have unnecessary degrees of freedom. Instead of using the word "minimum" inputs, the word "adequate" has been used to address a practical issue - if a system uses the minimum required information, it may not be able to stand any measurement error and hence a controlled level of redundancy should be kept. But how can we design such a system? Computational Intelligence (CI) is an excellent tool for this. In this talk, we shall discuss how CI, in particular, Neural Networks, Fuzzy Systems, and neuro-fuzzy systems can be used to realize parsimonious systems. We shall consider a few approaches to realize parsimony in designing algorithms for data visualization, classification, and prediction using neural and neuro-fuzzy systems. In this context, we shall also discuss, sensor selection, a generalized version of the feature selection problem.
