Bijector

class liesel.liesel.nodes.Bijector(bijector, input, inverse=False, distribution=None, name=None)

Bases: liesel.liesel.nodes.Node[liesel.liesel.nodes.BijectorCalculator]

A weak node with a BijectorCalculator.

Methods

grad()	Returns the gradient of the model log-probability w.r.t.
input_value_changed()	Informs the node that the value of one of its inputs has changed.
jaxify()	Enables JAX NumPy for the node.
own_value_changed()	Informs the node that its value has changed.
set_value(value[, update])	Sets the value of the node.
unjaxify()	Disables JAX NumPy for the node.
update()	Updates the value and the log-probability of the node.
validate()	Checks if the value and the log-probability of the node are finite.
