Simple rejection sampling
Webb6 maj 2016 · Our idea is a simple scheme to instantiate the rejected proposals preceding each data point. The resulting joint probability over observed and rejected variables can be much simpler than the marginal distribution over the observed variables, which often involves intractable integrals. WebbThe idea of rejection sampling is that although we cannot easily sample from \(f\), there exists another density \(g\), like a Normal distribution or perhaps a \(t\)-distribution, …
