Registering NMF Algorithms
Adds a new algorithm to the registry of algorithms that perform Nonnegative Matrix Factorization.
nmfRegisterAlgorithm is an alias to
setNMFMethod for backward compatibility.
setNMFMethod(name, method, ...,
overwrite = isLoadingNamespace(), verbose = TRUE)
nmfRegisterAlgorithm(name, method, ...,
overwrite = isLoadingNamespace(), verbose = TRUE)... |
arguments passed to the factory function
|
overwrite |
logical that indicates if any existing
NMF method with the same name should be overwritten
( |
verbose |
a logical that indicates if information
about the registration should be printed ( |
name |
name/key of an NMF algorithm. |
method |
definition of the algorithm |
# define/regsiter a new -- dummy -- NMF algorithm with the minimum arguments
# y: target matrix
# x: initial NMF model (i.e. the seed)
# NB: this algorithm simply return the seed unchanged
setNMFMethod('mynmf', function(y, x, ...){ x })
# check algorithm on toy data
res <- nmfCheck('mynmf')
# the NMF seed is not changed
