run_joinNMF_tensor: Join NMF

In hdsu-bioquant/ButchR: Non-Negative Matrix Factorization Suite

Join NMF

Description

Computes join NMF on tensorflow using the reticulate framework, uses a list of non-negative matrices as input

Usage

run_joinNMF_tensor(
  matrix_list,
  ranks = 2,
  n_initializations = 10,
  iterations = 10^4,
  convergence_threshold = 40,
  Sp = 0,
  extract_features = FALSE
)

Arguments

matrix_list	List of non-negative matrices
ranks	numeric vector with ranks to factorize
n_initializations	Number of initializations to evaluate
iterations	Maximum number of iterations to run for every initialization
convergence_threshold	The factorization stops, if the convergence test is constant for this number of iterations
Sp	Sparsity,
extract_features	if TRUE performs feature extraction for all factorization ranks > 2.

Value

An object of class ButchR_joinNMF. containing a join H matrix and one W matrix for each input matrix

Examples

## Not run: 
norm_mat_list <- list(a = matrix(abs(rnorm(1000)), ncol = 10),
                      b = matrix(abs(rnorm(1000)), ncol = 10))
jnmf_exp <- run_joinNMF_tensor(norm_mat_list,
                               ranks = 2:5,
                               n_initializations     = 10,
                               iterations            = 10^4,
                               convergence_threshold = 40)
