Hierarchical variational models
WebIn this paper we consider hierarchical variational models (Ranganath et al., 2016; Salimans et al., 2015; Agakov and Barber, 2004) where the approximate posterior q(z jx) is represented as a mixture of tractable distributionsR q(zj ;x) over some tractable mixing distribution q( jx): q(zjx) = Web10 de abr. de 2024 · Variational autoencoders (VAE) combined with hierarchical RNNs have emerged as a powerful framework for conversation modeling. However, they suffer …
