NettetSVC Implementation of Support Vector Machine classifier using libsvm: the kernel can be non-linear but its SMO algorithm does not scale to large number of samples as LinearSVC does. Furthermore SVC multi-class mode is implemented using one vs one scheme while LinearSVC uses one vs the rest. LinearSVC optimizes a linear model (like LogisticRegression or Lasso) with a complexity penalty via some gradient-based method, without regard for support vectors.
