A Simple Recipe for Contrastively Pre-training Video-First Encoders Beyond 16 Frames

CVPR 2024poster

Understanding long real-world videos requires modeling of long-range visual dependencies. To this end we explore video-first architectures building on the common paradigm of transferring large-scale image--text models to video via shallow temporal fusion. However we expose two limitations to the app…

Predicting Text Preference Via Structured Comparative Reasoning

ACL 2024long

Comparative reasoning plays a crucial role in predicting text preferences; however, large language models (LLMs) often demonstrate inconsistencies in their reasoning, leading to incorrect preference predictions. While approaches like Chain-of-Thought improve accuracy in many settings, they struggle…

UNcommonsense Reasoning: Abductive Reasoning about Uncommon Situations

NAACL 2024long

Language technologies that accurately model the dynamics of events must perform commonsense reasoning. Existing work evaluating commonsense reasoning focuses on making inferences about common, everyday situations. To instead investigate the ability to model unusual, unexpected, and unlikely situatio…

Abductive Commonsense Reasoning Exploiting Mutually Exclusive Explanations

ACL 2023long

Abductive reasoning aims to find plausible explanations for an event. This style of reasoning is critical for commonsense tasks where there are often multiple plausible explanations. Existing approaches for abductive reasoning in natural language processing (NLP) often rely on manually generated ann…

Tensor Variable Elimination for Plated Factor Graphs

ICML 2019oral

A wide class of machine learning algorithms can be reduced to variable elimination on factor graphs. While factor graphs provide a unifying notation for these algorithms, they do not provide a compact way to express repeated structure when compared to plate diagrams for directed graphical models. To…

Latent Alignment and Variational Attention

NeurIPS 2018poster

Neural attention has become central to many state-of-the-art models in natural language processing and related domains. Attention networks are an easy-to-train and effective method for softly simulating alignment; however, the approach does not marginalize over latent alignments in a probabilistic s…
