WebFeb 15, 2024 · Using Support Vectors to perform regression Because indeed, SVMs can also be used to perform regression tasks. We know that the decision boundary that was learned in the figure above can be used to separate between the two classes. WebSVM works really well with high-dimensional data. If your data is in higher dimensions, it is wise to use SVR. For data with a clear margin of separations, SVM works relatively well. When data has more features than the number of observations, SVM is one of the best algorithms to use.
