Performs parafac factorization via ALS
1 | Parafac(Y, R)
|
Y |
Array of dimension m1*m2*...*mK |
R |
Desired rank of the factorization. Defalust is all columns(range=1:R) |
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) |
