obj is the optimal objective value of the dual SVM problem. rho is the bias term in the decision function sgn(w^Tx - rho). nSV and nBSV are number of support vectors and bounded support vectors (i.e., alpha_i = C). nu-svm is a somewhat equivalent form of C-SVM where C is replaced by nu. nu simply shows the corresponding parameter.

According to the libsvm FAQ you can extract the support vectors from the model file: In the model file, after parameters and other informations such as labels , each line represents a support vector. But remember, these are only the support vectors, which are only a fraction of your original input data.

The support vector machines in scikit-learn support both dense (numpy.ndarray and convertible to that by numpy.asarray) and sparse (any scipy.sparse) sample vectors as input. However, to use an SVM to make predictions for sparse data, it must have been fit on such data.

Support-vector machine weights have also been used to interpret SVM models in the past. Posthoc interpretation of support-vector machine models in order to identify features used by the model to make predictions is a relatively new area of research with special significance in the biological sciences.

I am learning how to use libsvm through sklearn.svm in python. I read here about what happens and why when you change the C value as part of your model. My intuition from what I've learned would be that lower C values would use less support vectors to make a more general classification, while higher C values would use more support vectors to attempt to 'overfit' and account for all outliers.
