model where we have replaced b with y = σ_λ(z): * Applying the REINFORCE trick gets us the right hand side. We want the right hand side to take the form of the baseline term in our REINFORCE estimator of the unrelaxed model. We have 2 problems. The expectation is in terms of z and not b. Even if we
