initializePARAFAC: Initialize PARAFAC algorithm input vectors

Description

Initialize PARAFAC algorithm input vectors

Usage

initializePARAFAC(Tensor, nfac, initialization = "random", output = "Fac")

Value

Fac or vector with initialized components.

Arguments

Tensor

Input dataset matrix or tensor

nfac

Number of components to initialize.

initialization

Either "random" for random initialization or "svd" for svd based.

output

Output the initialized components as a Fac object ("Fac", default) or as a vector ("vect").

Examples

A = array(rnorm(108,2), c(108,2))
B = array(rnorm(100,2), c(100,2))
C = array(rnorm(10,2), c(10,2))
Tensor = reinflateTensor(A, B, C, returnAsTensor=TRUE)
init = initializePARAFAC(Tensor, 2)
