The most widely used classifiers are the neural network,[106] kernel methods such as the support vector machine,[107] k-nearest neighbor algorithm,[108] Gaussian mixture model,[109] naive Bayes classifier,[110] and decision tree.

k-nearest neighbor algorithm (k-NN) is a method for classifying objects based on closest training examples in the feature space.
