Hi @Yuvarani Sadatcharam,

You can use “fitgmdist” function in MATLAB to represent your extracted features using GMM.

Here is a working example of the same.

% Normalize the feature data
features = zscore(features);

% Define a small regularization value (optional)
regValue = 0.01;

% You can set options for the fitting process
options = statset('MaxIter', 1000, 'Display', 'final');

% Then, fit the Gaussian Mixture Model
gmm = fitgmdist(features, n_components, ...
    'RegularizationValue', regValue, ...
    'CovarianceType', 'diagonal', ...
    'Start', 'plus', ...
    'Options', options);

% Display the GMM parameters
disp(gmm);

For more details about “fitgmdist” you can use the MATLAB command

doc fitgmdist

I hope this helps!
