coef.gensvm: Get the coefficients of the fitted GenSVM model

In gensvm: A Generalized Multiclass Support Vector Machine

Get the coefficients of the fitted GenSVM model

Description

Returns the model coefficients of the GenSVM object

Usage

## S3 method for class 'gensvm'
coef(object, ...)

Arguments

object	a gensvm object
...	further arguments are ignored

Value

The coefficients of the GenSVM model. This is a matrix of size (n_{features} + 1) x (n_{classes} - 1). This matrix is used to project the input data to a low dimensional space using the equation: XW + t where X is the input matrix, t is the first row of the matrix returned by this function, and W is the n_{features} x (n_{classes} - 1) matrix formed by the remaining rows.
