Instances of this class represent how sampling is reparameterized.
tf.distributions.ReparameterizationType(
rep_type
)
Two static instances exist in the distributions library, signifying one of two possible properties for samples from a distribution:
FULLY_REPARAMETERIZED
: Samples from the distribution are fully
reparameterized, and straight-through gradients are supported.
NOT_REPARAMETERIZED
: Samples from the distribution are not fully
reparameterized, and straight-through gradients are either partially
unsupported or are not supported at all. In this case, for purposes of
e.g. RL or variational inference, it is generally safest to wrap the
sample results in a stop_gradients
call and use policy
gradients / surrogate loss instead.
Methods
__eq__
__eq__(
other
)
Determine if this ReparameterizationType
is equal to another.
Since RepaparameterizationType instances are constant static global instances, equality checks if two instances' id() values are equal.
