trainig anfis using woa in matlab

To train an ANFIS (Adaptive Neuro-Fuzzy Inference System) using the WOA (Whale Optimization Algorithm) in MATLAB, you can follow these steps:

  1. Install the ANFIS and WOA libraries in MATLAB if you haven't already. You can find these libraries on the MATLAB File Exchange or other reliable sources.

  2. Create a MATLAB script and import the necessary libraries:

main.m
% Import ANFIS and WOA libraries
addpath('path/to/anfis/library');
addpath('path/to/woa/library');

4 lines
  1. Load your dataset and preprocess it if needed:
main.m
data = load('path/to/your/dataset.mat');
inputs = data.inputs; % your input data
outputs = data.outputs; % your output data

4 lines
  1. Define the ANFIS structure and initial parameters:
main.m
numMFs = 3; % number of membership functions per input variable
mfType = 'gaussmf'; % type of membership function (e.g., 'gaussmf', 'trimf')
inputRange = [min(inputs(:)) max(inputs(:))]; % input range for membership function
outputRange = [min(outputs(:)) max(outputs(:))]; % output range for membership function

fis = genfis1(inputs, outputs, mfType, numMFs); % generate initial fuzzy inference system

7 lines
  1. Define the fitness function for the WOA algorithm. This function should evaluate the performance of the ANFIS model using a specific metric (e.g., mean squared error, accuracy).
main.m
fitnessFunction = @(x) evaluateANFIS(x, fis, inputs, outputs); % wrapper function to evaluate ANFIS

2 lines
  1. Set the WOA parameters and run the optimization process:
main.m
maxIterations = 100; % maximum number of iterations
numWhales = 20; % number of whales in the population

bestSolution = WOA(fitnessFunction, inputRange, outputRange, maxIterations, numWhales);

194 chars
5 lines
  1. Finally, train the ANFIS model using the best solution obtained from the WOA optimization:
main.m
fis = genfis2(inputs, outputs, bestSolution); % train ANFIS with the best solution

83 chars
2 lines

You can now use the trained ANFIS model for prediction or further analysis.

Please note that this is a general outline, and you may need to adapt it to your specific problem or dataset. Make sure to refer to the documentation of the ANFIS and WOA libraries for more detailed instructions and examples.
