SVM support Vector Machine
support vectors: refers to the most difficult data points in the training set that are closest to the classification decision surface."Machine": that is, machine machines, is actually an algorithm. In the field of machine learning, some algorithms are often regarded as a machine (or learning machine, predictive function, learning function, etc.).
SVM is a supervised learning method, that is, the category of the known training point, and the corresponding relationship
possible to learn the true error directly, only the training error can be calculated:where [M] = {1,..., m}, starting from predictor H to minimizing LS (h) is called empirical minimization, referred to as ERM. Erm may have been fitted, LS (h) Small does not represent L d,f (h) small.
