One-class SVM is used for novelty detection, that is, given a set of samples, it will detect the soft boundary of that set so as to classify new points as belonging to that set or not. The class that implements this is called OneClassSVM.

In this case, as it is a type of unsupervised learning, the fit method will only take as input an array X, as there are no class labels.
