It tells us how well the entire model class explains the data, balances data fit (likelihood) with model complexity (prior volume), and serves as an objective for model comparison and model selection.

Variational inference trades the asymptotic exactness of MCMC-style sampling for tractable, fast, gradient-based optimisation in a chosen surrogate family, at the price that the result is only as good …

Oct 30, 2019 · In this blog post, we reframe Bayesian inference as an optimization problem using variational inference, markedly speeding up computation.

The numerator is easy to compute for any con guration of the hidden variables. The problem is the denominator. Let's try to compute it. First, we can take advantage of the conditional independence of …
