Overview of statistical models for feature recognition of music element analysis techniques.

Model type	Model instance	Model features	Model method
State model	Hidden Markov model (HMM)	Fine spectrum timing structure	HMM is trained by feature set, maps -dimensional features to a state, and classifies homogeneous features
Probability distribution model	Single/mixed Gaussian model (GMM)	Global statistics	Build a probability distribution model for a feature and use global statistical methods to identify the feature
Sequence model	Time series	Timing features sequence	Use the corresponding relationship between the time series feature sequence and the original music to directly describe a certain attribute of the original music on a larger time scale
