	Label Field	Table field	`FIELD`	-	-
	Use Label as Identifier	Boolean	`LABEL_AS_ID`	Use training area labels as identifier in classification result, assumes all label values are integer numbers!	Default: 0
	Minimum Redundancy Feature Selection	Boolean	`DO_MRMR`	Use only features selected by the minimum Redundancy Maximum Relevance (mRMR) algorithm	Default: 0
	Number of Features	Integer	`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	`mRMR_THRESHOLD`	a double number of the discretization threshold; set to 0 to make binarization	Minimum: 0.000000 Default: 1.000000
	Selection Method	Choice	`mRMR_METHOD`	-	Available Choices: [0] Mutual Information Difference (MID) [1] Mutual Information Quotient (MIQ) Default: 0

	Sample with Replacement	Boolean	`RF_REPLACE`	Sample from training population with or without replacement?	Default: 1
	Minimum Node Split Size	Integer	`RF_SPLIT_MIN_SIZE`	Number of examples required for a node to be split. Choose 1 for complete growing.	Minimum: 1 Default: 1
	Features per Node	Choice	`RF_NODE_FEATURES`	-	Available Choices: [0] logarithmic [1] square root [2] all Default: 1
	Stratification	Choice	`RF_STRATIFICATION`	Specifies stratification strategy. Either none, equal amount of class samples, or proportional to fraction of class samples.	Available Choices: [0] none [1] equal [2] proportional Default: 0
