RandMatBinary: Create a Random Matrix: Binary

In rerf: Randomer Forest

Description

Create a Random Matrix: Binary

Usage

RandMatBinary(p, d, sparsity, prob, catMap = NULL, ...)

Arguments

p	the number of dimensions.
d	the number of desired columns in the projection matrix.
sparsity	a real number in (0,1) that specifies the distribution of non-zero elements in the random matrix.
prob	a probability \in (0,1) used for sampling from {-1,1} where prob = 0 will only sample -1 and prob = 1 will only sample 1.
catMap	a list specifying specifies which one-of-K encoded columns in X correspond to the same categorical feature.
...	used to handle superfluous arguments passed in using paramList.

Value

A random matrix to use in running RerF.

Examples

p <- 8
d <- 3
sparsity <- 0.25
prob <- 0.5
set.seed(4)
(a <- RandMatBinary(p, d, sparsity, prob))
