Is there any method to find the optimal features for cluster analysis using MATLAB? Can we use silhouette plot (cluster width and silhouette coefficient ) to select the most relevant features

Hi Arun,
I understand that you are trying to find out optimal features for cluster analysis and considering ‘silhouette plot’ as an option. You can use ‘k-means’ clustering and ‘silhouette plot’ iteratively by varying cluster sizes and different mix of features to be able to find out optimal features. You can refer to the following link to further understand usage of k-means and silhouette plot:
