Ramos, "eFSLab: Developing evolving fuzzy systems from data in a friendly environment," 2009 European Control Conference (ECC), Budapest, Hungary, 2009, pp. 922-927, doi: 10.23919/ECC.2009.7074522http://hdl.handle.net/10400.8/16357A software lab is presented to support the development of fuzzy systems from data (data-driven approach) avoiding redundancy and unnecessary complexity in the obtained membership functions, in order to give some semantic meaning to the results. On-line mechanisms for merging membership functions and rule base simplification are implemented improving interpretability and transparency of the produced fuzzy models, allowing the minimization of redundancy and complexity of the models during their development, contributing to the transparency of the obtained rules. The application, developed in Matlab environment, and public under GNU license, is applied to one benchmark problem- the Box-Jenkins time series prediction- with illustrative results.engFuzzy setsFuzzy systemsMergingBiological system modelingComputational modelingComplexity theoryBenchmark testingconference paper10.23919/ecc.2009.7074522
