Random Forest Classification (ViGrA)

Inputs

Features

format
href
Please set a value for FEATURES.

Feature Probabilities

boolean

Training Areas

format
href
Please set a value for TRAINING.

Label Field

format
href
Please set a value for FIELD.

Use training area labels as identifier in classification result, assumes all label values are integer numbers!

boolean

Use only features selected by the minimum Redundancy Maximum Relevance (mRMR) algorithm

boolean

Number of Features

integer

uncheck this means no discretizaton (i.e. data is already integer)

boolean

a double number of the discretization threshold; set to 0 to make binarization

number

Selection Method

string

Import from File

format
href
Please set a value for RF_IMPORT.

Export to File

format
href
Please set a value for RF_EXPORT.

How many trees to create?

integer

Specifies the fraction of the total number of samples used per tree for learning.

number

Sample from training population with or without replacement?

boolean

Number of examples required for a node to be split. Choose 1 for complete growing.

integer

Features per Node

string

Specifies stratification strategy. Either none, equal amount of class samples, or proportional to fraction of class samples.
