Discretization method.

Type	Definition	Characteristic	Specific representative method
Unsupervised discretization	A method that does not use class information in the discretization process	The method is simple and easy to operate, but it needs to specify the number of intervals artificially	Equal width box method
			Equal frequency box method
			String analysis method
Supervised discretization	A method that uses class information in the discretization process	There is no need to specify the number of intervals artificially, but the operation is complex	IR method
			Entropy based discretization method
			Discretization method based on chi square
