    x,
    collection=None
)

Defined in edward/util/random_variables.py.

Get descendant random variables of input.

Args:

• x: RandomVariable or tf.Tensor. Query node to find descendants of.
• collection: list of RandomVariable. The collection of random variables to check with respect to; defaults to all random variables in the graph.

Returns:

list of RandomVariable. Descendant random variables of x.

Examples

a = Normal(0.0, 1.0)
b = Normal(a, 1.0)
c = Normal(a, 1.0)
d = Normal(c, 1.0)
assert set(ed.get_descendants(a)) == set([b, c, d])
