simulateNMF: Simulate an NMF dataset

In zdebruine/RcppML: Rcpp Machine Learning Library

Simulate an NMF dataset

Description

Generate a random matrix that follows some defined NMF model to test NMF factorizations. Adapts methods from NMF::syntheticNMF.

Usage

simulateNMF(nrow, ncol, k, noise = 0.5, dropout = 0.5, seed = NULL)

Arguments

nrow	number of rows
ncol	number of columns
k	true rank of simulated model
noise	standard deviation of Gaussian noise centered at 0 to add to input matrix. Any negative values after noise addition are set to 0.
dropout	density of dropout events
seed	seed for random number generation

Value

list of dense matrix A and true w and h models
