NettetWhen dual is set to False the underlying implementation of LinearSVC is not random and random_state has no effect on the results. Using L1 penalization as provided by LinearSVC (penalty='l1', dual=False) yields a sparse solution, i.e. only a subset of feature weights is different from zero and contribute to the decision function.
