WebSVM Training ¶. To use Vector Support Classification (SVC) algorithm, we need define the model kernel. Let us use linear kernel. Then, we use the fit () function to train the model with our training data. In [7]: svc = svm.SVC(kernel='linear').fit(X_training,y_training) svc. WebWatch on. video II. The Support Vector Machine (SVM) is a linear classifier that can be viewed as an extension of the Perceptron developed by Rosenblatt in 1958. The Perceptron guaranteed that you find a hyperplane if it exists. The SVM finds the maximum margin separating hyperplane. Setting: We define a linear classifier: h(x) = sign(wTx + b ...
