A Discrete Variational Recurrent Topic Model without the Reparametrization Trick

1 code implementation NeurIPS 2020 Mehdi Rezaee, Francis Ferraro

We show how to learn a neural topic model with discrete random variables---one that explicitly models each word's assigned topic---using neural variational inference that does not rely on stochastic backpropagation to handle the discrete variables.

Learning a Reversible Embedding Mapping using Bi-Directional Manifold Alignment

no code implementations Findings (ACL) 2021 Ashwinkumar Ganesan, Francis Ferraro, Tim Oates

We propose a Bi-Directional Manifold Alignment (BDMA) that learns a non-linear mapping between two manifolds by explicitly training it to be bijective.

Neural Bregman Divergences for Distance Learning

no code implementations9 Jun 2022 Fred Lu, Edward Raff, Francis Ferraro

Many metric learning tasks, such as triplet learning, nearest neighbor retrieval, and visualization, are treated primarily as embedding tasks where the ultimate metric is some variant of the Euclidean distance (e. g., cosine or Mahalanobis), and the algorithm must learn to embed points into the pre-chosen space.
