HYRR: Hybrid Infused Reranking for Passage Retrieval

Jing Lu, Keith Hall, Ji Ma +1

We present Hybrid Infused Reranking for Passages Retrieval (HYRR), a framework for training rerankers based on a hybrid of BM25 and neural retrieval models. Retrievers based on hyb…

Learning List-Level Domain-Invariant Representations for Ranking

Ruicheng Xian, Honglei Zhuang, Zhen Qin +7

Domain adaptation aims to transfer the knowledge learned on (data-rich) source domains to (low-resource) target domains, and a popular method is invariant representation learning,…

LEAD: Liberal Feature-based Distillation for Dense Retrieval

Hao Sun, Xiao Liu, Yeyun Gong +6

Knowledge distillation is often used to transfer knowledge from a strong teacher model to a relatively weak student model. Traditional methods include response-based methods and fe…

SimANS: Simple Ambiguous Negatives Sampling for Dense Text Retrieval

Kun Zhou, Yeyun Gong, Xiao Liu +8

Sampling proper negatives from a large document pool is vital to effectively train a dense retrieval model. However, existing negative sampling strategies suffer from the uninforma…

RankT5: Fine-Tuning T5 for Text Ranking with Ranking Losses

Honglei Zhuang, Zhen Qin, Rolf Jagerman +6

Recently, substantial progress has been made in text ranking based on pretrained language models such as BERT. However, there are limited studies on how to leverage more powerful s…

Promptagator: Few-shot Dense Retrieval From 8 Examples

Zhuyun Dai, Vincent Y. Zhao, Ji Ma +7

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 lim…

PROD: Progressive Distillation for Dense Retrieval

Zhenghao Lin, Yeyun Gong, Xiao Liu +8

Knowledge distillation is an effective way to transfer knowledge from a strong teacher to an efficient student model. Ideally, we expect the better the teacher is, the better the s…

ED2LM: Encoder-Decoder to Language Model for Faster Document Re-ranking Inference

Kai Hui, Honglei Zhuang, Tao Chen +8

State-of-the-art neural models typically encode document-query pairs using cross-attention for re-ranking. To this end, models generally utilize an encoder-only (like BERT) paradig…

Large Dual Encoders Are Generalizable Retrievers

Jianmo Ni, Chen Qu, Jing Lu +8

It has been shown that dual encoders trained on one domain often fail to generalize to other domains for retrieval tasks. One widespread belief is that the bottleneck layer of a du…

Neural Passage Retrieval with Improved Negative Contrast

Jing Lu, Gustavo Hernandez Abrego, Ji Ma +2

In this paper we explore the effects of negative sampling in dual encoder models used to retrieve passages for automatic question answering. We explore four negative sampling strat…

Aligning the Pretraining and Finetuning Objectives of Language Models

Nuo Wang Pierse, Jingwen Lu

We demonstrate that explicitly aligning the pretraining objectives to the finetuning objectives in language model training significantly improves the finetuning task performance an…
