Parafac: Performs parafac factorization via ALS

In SuperPCA: Supervised Principal Component Analysis

Description

Performs parafac factorization via ALS

Usage

Parafac(Y, R)

Arguments

Y	Array of dimension m1*m2*...*mK
R	Desired rank of the factorization. Defalust is all columns(range=1:R)

Value

list with components

U:	List of basis vectors for parafac factorization, U[k]: mk*R for k=1,...,K. Columns of U[K] have norm 1 for k>1.
SqError:	Vector of squared error for the approximation at each iteration (should be non-increasing)

Examples

A <- array(stats::rnorm(100*10*10), dim=c(100,10,10))
Parafac(A,4)
