I want to compare number of support vectors in different SVM model. I have data for training/testing. I wan't to see how different are the numbers of support vectors in case of …

Sep 10, 2019 · For regression and one-class models, label is unchanged. - Function: void svm_get_sv_indices(const struct svm_model *model, int *sv_indices) This function outputs indices of support vectors into an array called sv_indices. The size of sv_indices is the number of support vectors and can be obtained by calling svm_get_nr_sv.

For dual solvers, we output only the primal weight vector w, so support vectors are not stored in the model. This is different from LIBSVM. To know support vectors, you can modify the following loop in solve_l2r_l1l2_svc() of linear.cpp to print out indices:

Enable verbose output. Note that this setting takes advantage of a per-process runtime setting in libsvm that, if enabled, may not work properly in a multithreaded context. max_iter int, optional (default=-1) Hard limit on iterations within solver, or -1 for no limit. Attributes support_ array …

I have read in the MATLAB documentation, that the number of Support Vectors is connected to the value of the soft-margin parameter C - why is that, and how can we see that with regards to the objective function for SVM?

̶ The implementation is based on libsvm. The fit time complexity is more than quadratic with the number of samples which makes it hard to scale to dataset with more than a couple of 10000 samples. ̶ The multiclass support is handled according to a one-vs-one scheme LibSVM: ̶ LIBSVM implements the SMO algorithm for kernelized support vector

SVM models can be used for regression problems. The model consists of a number of support vectors (essentially samples selected from the calibration set) and non-linear model coefficients which define the non-linear mapping of variables in the input x-block. The …
