Bijector which applies a sequence of bijectors
tfb_chain(
bijectors = NULL,
validate_args = FALSE,
validate_event_size = TRUE,
parameters = NULL,
name = NULL
)a bijector instance.
list of bijector instances. An empty list makes this bijector equivalent to the Identity bijector.
Logical indicating whether arguments should be checked for correctness.
Checks that bijectors are not applied to inputs with
incomplete support (that is, inputs where one or more elements are a
deterministic transformation of the others). For example, the following
LDJ would be incorrect:
tfb_chain(list(tfb_scale(), tfb_softmax_centered()))$forward_log_det_jacobian(matrix(1:2, ncol = 2))
The jacobian contribution from tfb_scale() applies to a 2-dimensional input,
but the output from tfb_softmax_centered() is a 1-dimensional input embedded
in a 2-dimensional space. Setting validate_event_size=TRUE (default)
prints warnings in these cases. When validate_args is also TRUE, the
warning is promoted to an exception.
Locals dict captured by subclass constructor, to be used for copy/slice re-instantiation operators.
String, name given to ops managed by this object. Default:
E.g., tfb_chain(list(tfb_exp(), tfb_softplus()))$name == "chain_of_exp_of_softplus".
For usage examples see tfb_forward(), tfb_inverse(), tfb_inverse_log_det_jacobian().
