layer_mixture_same_family: A mixture (same-family) Keras layer.

In rstudio/tfprobability: Interface to 'TensorFlow Probability'

A mixture (same-family) Keras layer.

Description

A mixture (same-family) Keras layer.

Usage

layer_mixture_same_family(
  object,
  num_components,
  component_layer,
  convert_to_tensor_fn = tfp$distributions$Distribution$sample,
  validate_args = FALSE,
  ...
)

Arguments

object	What to compose the new Layer instance with. Typically a Sequential model or a Tensor (e.g., as returned by layer_input()). The return value depends on object. If object is: missing or NULL, the Layer instance is returned. a Sequential model, the model with an additional layer is returned. a Tensor, the output tensor from layer_instance(object) is returned.
num_components	Number of component distributions in the mixture distribution.
component_layer	Function that, given a tensor of shape batch_shape + [num_components, component_params_size], returns a tfd.Distribution-like instance that implements the component distribution (with batch shape batch_shape + [num_components]) – e.g., a TFP distribution layer.
convert_to_tensor_fn	A callable that takes a tfd$Distribution instance and returns a tf$Tensor-like object. Default value: tfd$distributions$Distribution$sample.
validate_args	Logical, default FALSE. When TRUE distribution parameters are checked for validity despite possibly degrading runtime performance. When FALSE invalid inputs may silently render incorrect outputs. Default value: FALSE. @param ... Additional arguments passed to args of keras::create_layer.
...	Additional arguments passed to args of keras::create_layer.
