WebThe margin, γ, is the distance from the hyperplane (solid line) to the closest points in either class (which touch the parallel dotted lines). Typically, if a data set is linearly separable, there are infinitely many separating hyperplanes. A natural question to ask is: Question: What is the best separating hyperplane? WebThe implementation is based on libsvm. The fit time scales at least quadratically with the number of samples and may be impractical beyond tens of thousands of samples. For large datasets consider using LinearSVC or SGDClassifier instead, possibly after a Nystroem transformer or other Kernel Approximation.
