When in Doubt, Think Slow: Iterative Reasoning with Latent Imagination

Martin Benfeghoul, Umais Zahid, Qinghai Guo +1

In an unfamiliar setting, a model-based reinforcement learning agent can be limited by the accuracy of its world model. In this work, we present a novel, training-free approach to…

Weakly-Supervised Action Localization by Hierarchically-structured Latent Attention Modeling

Guiqin Wang, Peng Zhao, Cong Zhao +5

Weakly-supervised action localization aims to recognize and localize action instancese in untrimmed videos with only video-level labels. Most existing models rely on multiple insta…

Predictive Coding as a Neuromorphic Alternative to Backpropagation: A Critical Evaluation

Umais Zahid, Qinghai Guo, Zafeirios Fountas

Backpropagation has rapidly become the workhorse credit assignment algorithm for modern deep learning methods. Recently, modified forms of predictive coding (PC), an algorithm with…

Long-horizon video prediction using a dynamic latent hierarchy

Alexey Zakharov, Qinghai Guo, Zafeirios Fountas

The task of video prediction and generation is known to be notoriously difficult, with the research in this area largely limited to short-term predictions. Though plagued with nois…
