Introduction to Pattern Recognition 2018/5/26 Machine Learning: Pattern Recognition Introduction to Pattern Recognition J.-S. Roger Jang (張智星) CSIE Dept., National Taiwan University http://mirlab.org/jang jang@mirlab.org ... In this talk, we are going to apply two neural network controller design techniques to fuzzy controllers, and construct the so-called on-line adaptive neuro-fuzzy controllers for nonlinear control systems. We are going to use MATLAB, SIMULINK and Handle Graphics to demonstrate the concept. So you can also get a preview of some of the features of the Fuzzy Logic Toolbox, or FLT, version 2.
