Autoregressively masked dense layer — tfb_masked_dense • tfprobability

Analogous to tf$layers$dense.

tfb_masked_dense(
  inputs,
  units,
  num_blocks = NULL,
  exclusive = FALSE,
  kernel_initializer = NULL,
  reuse = NULL,
  name = NULL,
  ...
)

Arguments

inputs	Tensor input.
units	integer scalar representing the dimensionality of the output space.
num_blocks	integer scalar representing the number of blocks for the MADE masks.
exclusive	logical scalar representing whether to zero the diagonal of the mask, used for the first layer of a MADE.
kernel_initializer	Initializer function for the weight matrix. If NULL (default), weights are initialized using the `tf$glorot_random_initializer`
reuse	logical scalar representing whether to reuse the weights of a previous layer by the same name.
name	string used to describe ops managed by this function.
...	`tf$layers$dense` arguments

Value

tensor
