Separating data with the maximum margin in ml

WebFigure 19. Linear decision boundaries obtained by logistic regression with equivalent cost (A). Linear decision boundary obtained through large margin classification (B). The SVM tries to separate the data with the largest margin possible, for this reason the SVM is sometimes called large margin classifier. WebThe Perceptron was arguably the first algorithm with a strong formal guarantee. If a data set is linearly separable, the Perceptron will find a separating hyperplane in a finite number of updates. (If the data is not linearly separable, it will loop forever.) The argument goes as follows: Suppose ∃w ∗ such that yi(x⊤w ∗) > 0 ∀(xi, yi ...

WebThis is the dividing line that maximizes the margin between the two sets of points. Notice that a few of the training points just touch the margin: they are indicated by the black circles in this figure. These points are the pivotal elements of this fit, and are known as the support vectors, and give the algorithm its name.
