Hi everyone,
For training anfis with matlab fuzzy logic toolbox, we can either choose backprpagation or hybrid method as given here http://www.mathworks.com/help/toolbox/fuzzy/anfis.html under 'optMethod'. But I want to train my ANFIS with Firefly Algorithm (FA). And I'm not able to figure out how I can implement my FA algorithm as a training method in ANFIS as I can't find if there is anyway to customize anfis training. Please help me on how can I train my anfis with my FA method.
