Common machine learning algorithms and features.

Sequence	Algorithm	Feature
1	K-nearest neighbor algorithm	Partitioning the feature space
2	BP neural network	Clear model, simple structure, and small amount of calculation
3	Extreme learning machine	The weights of the hidden layer nodes do not need to be updated, and the learning process only calculates the output weights
4	Support vector machines	Empirical and structural risk
