Seq vs Seq: An Open Suite of Paired Encoders and Decoders

Orion Weller, Kathryn Ricci, Marc Marone +3

The large language model (LLM) community focuses almost exclusively on decoder-only language models, since they are easier to use for text generation. However, a large subset of th…

ColBERT-Zero: To Pre-train Or Not To Pre-train ColBERT models

Antoine Chaffin, Luca Arnaboldi, Amélie Chatelain +1

Current state-of-the-art multi-vector models are obtained through a small Knowledge Distillation (KD) training step on top of strong single-vector models, leveraging the large-scal…
