Detailed Description

template<typename I, typename O, typename V, template< class, class, class... > class Q, typename... Ts>
struct LikelihoodWeighting< I, O, V, Q, Ts >

Likelihood weighting importance sampling, using the prior as the proposal.

Suppose the probabilistic program factors as \(p(x,z) = p(x|z)p(z)\). This method samples values \(z \sim p(z)\). The weight of each sample is given by \(\log w = \log p(x|z)\).

Template Parameters

I	The input type of the probabilistic program
O	The output type of the probabilistic program
V	The type of the address(es) to be queried
Q	The class template of the queryer
Ts	The distribution types in the probabilistic program
