Evidence lower bound
text:
In variational Bayesian methods, the evidence lower bound is a useful lower bound on the log-likelihood of some observed data. The ELBO is useful because it provides a guarantee on the worst-case for the log-likelihood of some distribution which models a set of data. The actual log-likelihood may be higher because the ELBO includes a Kullback-Leibler divergence term which decreases the ELBO due to an internal part of the model being inaccurate despite good fit of the model overall. Thus improvin
