Dense Passage Retrieval for Open-Domain Question Answering

Authors: nan

Publication: TIPSTER (2020)

DOI: nan

AbstractOpen-domain question answering relies on efficient passage retrieval to select candidate contexts, where traditional sparse vector space models, such as TF-IDF or BM25, are the de facto method. In this …...

Reduce Catastrophic Forgetting of Dense Retrieval Training with Teleportation Negatives

Authors: nan

Publication: TIPSTER (2022)

DOI: nan

AbstractIn this paper, we investigate the instability in the standard dense retrieval training, which iterates between model training and hard negative selection using the being-trained model. We show the catastrophic …...

Questions Are All You Need to Train a Dense Passage Retriever

Authors: nan

Publication: TIPSTER (2023)

DOI: nan

AbstractWe introduce ART, a new corpus-level autoencoding approach for training dense retrieval models that does not require any labeled training data. Dense retrieval is a central challenge for open-domain tasks, …...
