Type-2 fuzzy logic controller design optimization using the PSO approach for ECG prediction

Mahmut Dirik

Volume 3, Issue 2 , June 2022, , Pages 158-168


  In this study, a hybrid model for prediction issues based on IT2FLS and Particle Swarm Optimization (PSO) is proposed. The main contribution of this work is to discover the ideal strategy for creating an optimal value vector to optimize the membership function of the fuzzy controller. It should be emphasized ...  Read More

Uduak Umoh; Imo Eyoh; Etebong Isong; Anietie Ekong; Salvation Peter

Volume 1, Issue 3 , September 2020, , Pages 206-226


  Several attempts had been made to analyze emotion words in the fields of linguistics, psychology and sociology; with the advent of computers, the analyses of these words have taken a different dimension. Unfortunately, limited attempts have so far been made to using interval type-2 fuzzy logic (IT2FL) ...  Read More
