lol.sims.xor2 {lolR}

Xor Problem

Description

A function to simulate from the 2-class xor problem.

Usage

lol.sims.xor2(n, d, priors = NULL, fall = 100)

Arguments

n

the number of samples of the simulated data.

d

the dimensionality of the simulated data.

priors

the priors for each class. If NULL, class priors are all equal. If not null, should be |priors| = K, a length K vector for K classes. Defaults to NULL.

fall

the falloff for the covariance structuring. Sigma declines by ndim/fall across the variance terms. Defaults to 100.

Value

A list of class simulation with the following:

X

[n, d] the n data points in d dimensions as a matrix.

Y

[n] the n labels as an array.

mus

[d, K] the K class means in d dimensions.

Sigmas

[d, d, K] the K class covariance matrices in d dimensions.

priors

[K] the priors for each of the K classes.

simtype

The name of the simulation.

params

Any extraneous parameters the simulation was created with.
