Linear Map Function Gradient
Description
This function implements the gradient of the linear map function with respect
to coeff used for linear SVM and linear regression in the form required by
EmpiricalRiskMinimizationDP.CMS
and
EmpiricalRiskMinimizationDP.KST
.
Usage
mapXy.gr.linear(X, coeff)
Arguments
X |
Matrix of data. |
coeff |
Vector or matrix of coefficients or weights. |
Value
Matrix of values of the gradient of the linear map function with respect to each value of coeff.
Examples
X <- matrix(c(1,2,3,4,5,6),nrow=2)
coeff <- c(0.5,-1,2)
mapXy.gr.linear(X,coeff)
