sepNMF: Single Data Set Decomposition with Nonnegative Matrix...

In CHuanSite/PJD: Partial and Joint Decomposiiton(PJD)

Description

Apply NMF (Nonnegative Matrix Factorization) to a single data set

Usage

sepNMF(dataset, comp_num, weighting = NULL, perturbation = 1e-04)

Arguments

dataset	A dataframe/matrix to be decomposed
comp_num	Number of NMFs to be extracted
weighting	Weighting of each dataset, initialized to be NULL
perturbation	A small perturbation to ensure nmf works well

Value

A list of scores and component

Examples

dataset = list(matrix(runif(5000, 1, 2), nrow = 100, ncol = 50))
comp_num = 2
res_sepNMF = sepNMF(dataset, comp_num)
