"Web26 ott 2024 · A Support Vector Machine (SVM) is a discriminative classifier formally defined by a separating hyperplane. In other words, given labeled training data (supervised learning), the algorithm outputs an optimal hyperplane that categorizes new examples. The most important question that arises while using SVM is how to decide the right hyperplane. " - Svm graph
