Promptagator: Few-shot Dense Retrieval From 8 Examples

2022 · arXiv (Cornell University)

Much recent research on information retrieval has focused on how to transfer from one task (typically with abundant supervised data) to various other tasks where supervision is limited, with the implicit assumption that it is …

Multi-Vector Retrieval as Sparse Alignment

2022 · arXiv (Cornell University)

Multi-vector retrieval models improve over single-vector dual encoders on many information retrieval tasks. In this paper, we cast the multi-vector retrieval problem as sparse alignment between query and document tokens. We propose AligneR, a novel …
