Description

Methods for nnmf object returned by nnmf

Usage

## S3 method for class 'nnmf'
predict(
  object,
  newdata,
  which = c("A", "W", "H"),
  method = object$options$method,
  loss = object$options$loss,
  ...
)

## S3 method for class 'nnmf'
print(x, ...)

Arguments

object	An NNMF object returned by nnmf
newdata	A new matrix of x. No required when which == 'A'
which	Either 'A' (default), 'W' or 'H'
method	Either 'scd' or 'lee'. Default to object$options$method
loss	Either 'mse' or 'mkl'. Default to object$options$loss
...	Further arguments passed to 'nnlm' or 'print'
x	An NNMF object returned by nnmf

Value
