Estimate the support of a high-dimensional distribution. The implementation is based on SVM in Scikit-learn supports both sparse and dense sample vectors as input. Support Vector Machines with Scikit-learn In this tutorial, you'll learn about Support Vector Machines, one of the most popular and widely used supervised machine learning algorithms. SVM offers very high accuracy compared to other classifiers such as logistic regression, and decision trees.

SVM performs very well with even a limited amount of data. In this post we'll learn about support vector machine for classification specifically. See the section about multi-class classification in the SVM section of the User Guide for details. coef_ : array, shape = [n_class-1, n_features] Weights assigned to the features (coefficients in the primal problem). Scikit Learn offers different implementations such as the following to train an SVM classifier. LIBSVM: LIBSVM is a C/C++ library specialised for SVM. The SVC class is the LIBSVM implementation and can be used to train the SVM classifier (hard/soft margin classifier).
