ask a question about weights for features in svc with rbf kernel
Hi experts and users, I am going to extact the pattern of svc. But I do not know how to extract weights for each feature using this svc classifiers with kernel of rbf function. Thank you. Rujing
Hi Guillaume Is it OK for rbf kernel? As the document said: Weights assigned to the features (coefficients in the primal problem). This is only available in the case of a linear kernel.

There is no coef_ for kernel SVMs. What exactly are you looking for? On 1/20/20 9:52 AM, Rujing Zha wrote:
