Web27 Dec 2024 · SVMs can have hard and soft margins. If you think as support vectors and the main classification line as a street, a hard margin SVM will try to place all instances off or at the edge of the street. This is not a bad strategy if the instances of all classes are divided into neat clusters.

Web0=1-support vector operator is introduced as a ﬁlter to prevent outliers from being support vectors during the training process. Hence, the method is expected to be relatively robust. … The soft-margin support vector machine described above is an example of an empirical risk minimization (ERM) algorithm for the hinge loss. Seen this way, support vector machines belong to a natural class of algorithms for statistical inference, and many of its unique features are due to the behavior of the hinge loss.
