Dear MatLab-Community,
I have a question regarding feature importance.
My input matrix has the the following form: 3000 observations and 240 predictors/features which are classified into 2 groups (0/1).
Now I want to rank the predictors by their contribution to the overall accuracy which is 84% according to the SVM algorithm.
What is the best way to do this and how do I make it statistically sound?
Best regards
Daniel

Please refer to this link, it nicely explained the techniques to figure out the feature importance in classification model like SVM: https://www.mathworks.com/matlabcentral/answers/406577-how-can-i-determine-feature-importance-of-an-svm-classifier
