•Basic idea of support vector machines: just like 1- layer or multi-layer neural nets –Optimal hyperplane for linearly separable patterns –Extend to patterns that are not linearly separable by transformations of original data to map into new space – the Kernel function •SVM algorithm for pattern recognition 3 This example shows how to train a support vector machine (SVM) regression model using the Regression Learner app, and then use the RegressionSVM Predict block for response prediction in … 2 Developed at AT&T Bell Laboratories by Vapnik with colleagues (Boser et al., 1992, Guyon et al., 1993, Vapnik et al., 1997), SVMs are one of the most robust prediction methods, being based on statistical learning frameworks or VC theoryproposed by Vapnik and Chervonenkis (1974) and Vapnik (1… ≥ {\displaystyle 0 }.
