Webtimates using REINFORCE (Williams,1992). The key ingredients are, therefore, binary la-tent variables and sparsity-inducing regulariza-tion, and therefore the solution is marked by non-differentiability. We propose to replace Bernoulli variables by rectiﬁed continuous random variables (Socci et al.,1998), for they exhibit both discrete WebPolicy gradient methods work by first choosing actions directly from a parameterized model, then secondly updating the weights of the model to nudge the next predictions towards higher expected returns. REINFORCE achieves this by collecting a full trajectory then updating the policy weights in a Monte Carlo-style.
