convertClass2Matrix: Convert A Vector of Factors to Matrix

In softmaxreg: Training Multi-Layer Neural Network for Softmax Regression and Classification

Description

Convert A Vector of Factors to Matrix

Usage

convertClass2Matrix(target)

Arguments

target

Vector of factor representing each class.

Details

This Function can be used to convert factor to matrix yMat, e.g. For type 'raw' softmaxReg function input yMat, softmax regression.

Examples

## This Function can be used to convert factor to matrix yMat.
## e.g. For type 'raw' softmaxReg function input yMat, softmax regression.
y = as.factor(c(rep(1,50),rep(2,50),rep(3,50)))
yMat = convertClass2Matrix(y)
nObs = dim(yMat)[1]
K = dim(yMat)[2]
nObs
K

Example output

[1] 150
[1] 3
