Transformers as Graph-to-Graph Models

1 code implementation27 Oct 2023 James Henderson, Alireza Mohammadshahi, Andrei C. Coman, Lesly Miculicich

We argue that Transformers are essentially graph-to-graph models, with sequences just being a special case.

Strong and Efficient Baselines for Open Domain Conversational Question Answering

no code implementations23 Oct 2023 Andrei C. Coman, Gianni Barlacchi, Adrià De Gispert

Unlike the Open Domain Question Answering (ODQA) setting, the conversational (ODConvQA) domain has received limited attention when it comes to reevaluating baselines for both efficiency and effectiveness.

Imposing Relation Structure in Language-Model Embeddings Using Contrastive Learning

1 code implementation CoNLL (EMNLP) 2021 Christos Theodoropoulos, James Henderson, Andrei C. Coman, Marie-Francine Moens

Though language model text embeddings have revolutionized NLP research, their ability to capture high-level semantic information, such as relations between entities in text, is limited.

An Incremental Turn-Taking Model For Task-Oriented Dialog Systems

2 code implementations28 May 2019 Andrei C. Coman, Koichiro Yoshino, Yukitoshi Murase, Satoshi Nakamura, Giuseppe Riccardi

To identify the point of maximal understanding in an ongoing utterance, we a) implement an incremental Dialog State Tracker which is updated on a token basis (iDST) b) re-label the Dialog State Tracking Challenge 2 (DSTC2) dataset and c) adapt it to the incremental turn-taking experimental scenario.
