Progressive Fusion for Multimodal Integration

no code implementations1 Sep 2022 Shiv Shankar, Laure Thompson, Madalina Fiterau

In this work, we present an iterative representation refinement approach, called Progressive Fusion, which mitigates the issues with late fusion representations.

Modeling Exemplification in Long-form Question Answering via Retrieval

no code implementations NAACL 2022 Shufan Wang, Fangyuan Xu, Laure Thompson, Eunsol Choi, Mohit Iyyer

We show that not only do state-of-the-art LFQA models struggle to generate relevant examples, but also that standard evaluation metrics such as ROUGE are insufficient to judge exemplification quality.

Phrase-BERT: Improved Phrase Embeddings from BERT with an Application to Corpus Exploration

1 code implementation EMNLP 2021 Shufan Wang, Laure Thompson, Mohit Iyyer

Phrase representations derived from BERT often do not exhibit complex phrasal compositionality, as the model relies instead on lexical similarity to determine semantic relatedness.

Topic Modeling with Contextualized Word Representation Clusters

no code implementations23 Oct 2020 Laure Thompson, David Mimno

Clustering token-level contextualized word representations produces output that shares many similarities with topic models for English text collections.

Authorless Topic Models: Biasing Models Away from Known Structure

1 code implementation COLING 2018 Laure Thompson, David Mimno

Most previous work in unsupervised semantic modeling in the presence of metadata has assumed that our goal is to make latent dimensions more correlated with metadata, but in practice the exact opposite is often true.

Quantifying the Effects of Text Duplication on Semantic Models

no code implementations EMNLP 2017 Alex Schofield, ra, Laure Thompson, David Mimno

Duplicate documents are a pervasive problem in text datasets and can have a strong effect on unsupervised models.
