Black-box -divergence Minimization

WebThis approach is known as black-box VB and it allows VB to be applied to almost any model. Here we propose a similar method for the more general problem of α-divergence minimization and call itblack-box alpha. For this, we simplify the energy function of EP so that the min-maxproblem is transformed into a minimization problem. WebBlack-box alpha divergence minimization. J. Hernandez-Lobato et al. (2016).

WebBlack box variational inference (BBVI) with reparameterization gradients triggered the exploration of divergence measures other than the Kullback-Leibler (KL) diver-gence, such as alpha divergences. In this paper, we view BBVI with generalized divergences as a form of estimating the marginal likelihood via biased importance sampling. WebBlack box variational inference (BBVI) with reparameterization gradients triggered the exploration of divergence measures other than the Kullback-Leibler (KL) divergence, such as alpha divergences. These divergences can be tuned to be more mass-covering (preventing overfitting in complex models), but are also often harder to optimize using …
