Parameters

	Name	Type	Identifier	Description	Constraints
Input	Table	Table (input)	`TABLE`	Table with features, must include class-ID	-
Output	Feature Importances	Table (output)	`IMPORTANCES`	-	-
Options	Features	Table fields	`FEATURES`	Select features (table fields) for classification	-
	Prediction (*)	Table field	`PREDICTION`	This is field that will have the prediction results. If not set it will be added to the table.	-
	Training	Table field	`TRAINING`	this is the table field that defines the training classes	-
	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
	Load Model	File path	`RF_IMPORT`	-	-
	Save Model	File path	`RF_EXPORT`	-	-
	Tree Count	Integer	`RF_TREE_COUNT`	How many trees to create?	Minimum: 1 Default: 32
	Samples per Tree	Floating point	`RF_TREE_SAMPLES`	Specifies the fraction of the total number of samples used per tree for learning.	Minimum: 0.000000 Maximum: 1.000000 Default: 1.000000
	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
(*) optional
