In the most general setting, instead of learning a deterministic encoding h given X, we posit a latent distribution over the hidden representation h, Pr(h|X) to model the overall document where Pr(h|X) is parameterized by a diagonal Gaussian distribution N (h|µ(X), σ 2 (X)).
consider the distribution Pr(Y |X) which can be written as follows: As noted by Miao et al.
