Symbolic Support Vector Machines Regression

Description

Symbolic Support Vector Machines Regression

Usage

sym.svm(
  formula,
  sym.data,
  method = c("cm", "crm"),
  scale = TRUE,
  kernel = "radial"
)

Arguments

formula

a symbolic description of the model to be fit.

sym.data

symbolic data.table

method

method

scale

A logical vector indicating the variables to be scaled. If scale is of length 1, the value is recycled as many times as needed. Per default, data are scaled internally (both x and y variables) to zero mean and unit variance. The center and scale values are returned and used for later predictions.

kernel

the kernel used in training and predicting. You might consider changing some of the following parameters, depending on the kernel type.
