Svm regression — wbt_svm_regression • whitebox

Performs a supervised SVM regression analysis using training site points and predictor rasters.

Usage

wbt_svm_regression(
  inputs,
  training,
  field,
  scaling = "Normalize",
  output = NULL,
  c = 50,
  eps = 10,
  gamma = 0.5,
  test_proportion = 0.2,
  wd = NULL,
  verbose_mode = NULL,
  compress_rasters = NULL,
  command_only = FALSE
)

Arguments

inputs: Names of the input predictor rasters.
training: Name of the input training site points Shapefile.
field: Name of the attribute containing class data.
scaling: Scaling method for predictors. Options include 'None', 'Normalize', and 'Standardize'.
output: Name of the output raster file.
c: c-value, the regularization parameter.
eps: Epsilon in the epsilon-SVR model.
gamma: Gamma parameter used in setting the RBF (Gaussian) kernel function.
test_proportion: The proportion of the dataset to include in the test split; default is 0.2.
wd: Changes the working directory. Default: NULL will use the value in WhiteboxTools settings, see wbt_wd() for details.
verbose_mode: Sets verbose mode. If verbose mode is FALSE, tools will not print output messages. Default: NULL will use the value in WhiteboxTools settings, see wbt_verbose() for details.
compress_rasters: Sets the flag used by 'WhiteboxTools' to determine whether to use compression for output rasters. Default: NULL will use the value in WhiteboxTools settings, see wbt_compress_rasters() for details.
command_only: Return command that would be executed by system() rather than running tool. Default: FALSE.

Value

Returns the tool text outputs.
