Web2 de fev. de 2024 · INTRODUCTION: Support Vector Machines (SVMs) are a type of supervised learning algorithm that can be used for classification or regression tasks. The main idea behind SVMs is to find a hyperplane that maximally separates the different classes in the training data. This is done by finding the hyperplane that has the largest … Web30 de set. de 2014 · For example, if you have set up a binary SVM then you will have likely also set up 2 labels (say -1 and 1). If the SVM decides that the Mat in question is of class -1 then it will return -1. The sign is dependent entirely on the labels you set, if you don't use a sign then there will be none.
