Unsupervised Representation Learning via Neural Activation Coding

1 code implementation7 Dec 2021 Yookoon Park, Sangho Lee, Gunhee Kim, David M. Blei

We argue that the deep encoder should maximize its nonlinear expressivity on the data for downstream predictors to take full advantage of its representation power.

A Hierarchical Latent Structure for Variational Conversation Modeling

4 code implementations NAACL 2018 Yookoon Park, Jaemin Cho, Gunhee Kim

To solve the degeneration problem, we propose a novel model named Variational Hierarchical Conversation RNNs (VHCR), involving two key ideas of (1) using a hierarchical structure of latent variables, and (2) exploiting an utterance drop regularization.
