WebbThere are two types of Support Vector Machines are: 1. Linear SVM: This type of SVM is useful when we have to deal with data that has exactly two distinguishing features for the data points. Here, the hyperplane for the dataset will be a straight line. Such a dataset that is separated by a line is linearly separable data. Webb31 mars 2024 · Support Vector Machine (SVM) is a supervised machine learning algorithm used for both classification and regression. Though we say regression problems as well it’s best suited for classification. The objective of the SVM algorithm is to find a hyperplane in an N-dimensional space that distinctly classifies the data points.
