Generalized Low-Rank Models (GLRM) on H2O

Description

Perform GLRM decomposition using h2o::h2o.glrm Given Input matrix A: ⁠A(m x n) = X(m x k) \%*\% Y(k x n)⁠

Usage

d_H2OGLRM(
  x,
  x.test = NULL,
  x.valid = NULL,
  k = 3,
  ip = "localhost",
  port = 54321,
  transform = "NONE",
  loss = "Quadratic",
  regularization.x = "None",
  regularization.y = "None",
  gamma.x = 0,
  gamma.y = 0,
  max_iterations = 1000,
  max_updates = 2 * max_iterations,
  init_step_size = 1,
  min_step_size = 1e-04,
  seed = -1,
  init = "PlusPlus",
  svd.method = "Randomized",
  verbose = TRUE,
  print.plot = TRUE,
  plot.theme = rtTheme,
  n.cores = rtCores,
  ...
)
