Non-negative Matrix Factorization
Package: 
NMFN
Version: 
2.0

Description

Non-negative Matrix Factorization

Usage

nnmf(x, k, method = "nnmf_mm", maxiter = 1000, eps = 2.2204e-16)

Arguments

x
original input matrix
k
number of factors / components
method
which method to use for matrix factorization (default - multiplicative update)
maxiter
max number of iterations
eps
small threshold value

Examples

X <- matrix(1:12,3,4) 
z.mm   <- nnmf(X,3)             # 3 factors via multiplicative update
z.als  <- nnmf(X,3,'nnmf_als')  # 3 factors via alternating least square
z.prob <- nnmf(X,3,'nnmf_prob') # 3 factors via multinomial
