tfp.experimental.distributions.log_prob_ratio(
p, x, q, y
)
Args
p
A distribution instance.
x
A tensor from the support of p.
q
A distribution instance in the same family as p, with matching shape.
y
A tensor from the support of q.
Returns
lp_ratio
log (p(x) / q(y)) = p.log_prob(x) - q.log_prob(y). In some cases
this will be computed with better than naive numerical precision, e.g. by
moving the difference inside of a sum reduction.
