Description

Identify the most relevant features for subsequent classification of tabular data. The minimum Redundancy Maximum Relevance (mRMR) feature selection algorithm has been developed by Hanchuan Peng .

Parameters

	Name	Type	Identifier	Description	Constraints
Input	Data	table, input	`DATA`	-	-
Output	Feature Selection	table, output	`SELECTION`	-	-
Options	Class Identifier	table field	`CLASS`	-	-
	Verbose Output	boolean	`VERBOSE`	output of intermediate results to execution message window	Default: 1
	Number of Features	integer number	`mRMR_NFEATURES`	-	Minimum: 1 Default: 50
	Discretization	boolean	`mRMR_DISCRETIZE`	uncheck this means no discretizaton (i.e. data is already integer)	Default: 1
	Discretization Threshold	floating point number	`mRMR_THRESHOLD`	a double number of the discretization threshold; set to 0 to make binarization	Minimum: 0.000000 Default: 1.000000
