Output of Scikit SVM in multiclass classification always gives same label

I am currently using Scikit learn with the following code: clf = svm.SVC(C=1.0, tol=1e-10, cache_size=600, kernel='rbf', gamma=0.0, class_weight='auto') and then do fit and predict for a set of data with 7 different labels. I got a…

How to use Particle Swarm Optimization for finding hyper-parameters of Support Vector Regression?

I want to use Particle Swarm Optimization (PSO)for finding hyper parameters of a support vector regression problem. Initially I tried to find the same using grid search method,but the Matlab code is taking too long to produce results. Even after…
