Abstract

Selection of relevant variables from a high dimensional process operation setting space is a problem frequently encountered in industrial process modeling. This paper presents two global relevancy criteria, which permit to formalize and combine the sensitivity of experimental data and the conformity of human knowledge using a liner and a fuzzy model, respectively. The performances of these relevancy criteria and some well-known selection methods are compared through artificial and real datasets. The result validates the outperformance of fuzzy global relevancy criterion, especially when the number of learning data is small and noisy.
