ExcluIR: Exclusionary Neural Information Retrieval

1 code implementation26 Apr 2024 WenHao Zhang, Mengqi Zhang, Shiguang Wu, Jiahuan Pei, Zhaochun Ren, Maarten de Rijke, Zhumin Chen, Pengjie Ren

However, in information retrieval community, there is little research on exclusionary retrieval, where users express what they do not want in their queries.

Mini-Ensemble Low-Rank Adapters for Parameter-Efficient Fine-Tuning

no code implementations27 Feb 2024 Pengjie Ren, Chengshun Shi, Shiguang Wu, Mengqi Zhang, Zhaochun Ren, Maarten de Rijke, Zhumin Chen, Jiahuan Pei

Parameter-efficient fine-tuning (PEFT) is a popular method for tailoring pre-trained large language models (LLMs), especially as the models' scale and the diversity of tasks increase.

Intent-calibrated Self-training for Answer Selection in Open-domain Dialogues

no code implementations13 Jul 2023 Wentao Deng, Jiahuan Pei, Zhaochun Ren, Zhumin Chen, Pengjie Ren

Specifically, it improves 2. 06% and 1. 00% of F1 score on the two datasets, compared with the strongest baseline with only 5% labeled data.

Transformer Uncertainty Estimation with Hierarchical Stochastic Attention

1 code implementation27 Dec 2021 Jiahuan Pei, Cheng Wang, György Szarvas

In this work, we propose a novel way to enable transformers to have the capability of uncertainty estimation and, meanwhile, retain the original predictive performance.

Pre-trained Language Models in Biomedical Domain: A Systematic Survey

1 code implementation11 Oct 2021 Benyou Wang, Qianqian Xie, Jiahuan Pei, Zhihong Chen, Prayag Tiwari, Zhao Li, Jie Fu

In this paper, we summarize the recent progress of pre-trained language models in the biomedical domain and their applications in biomedical downstream tasks.

ReMeDi: Resources for Multi-domain, Multi-service, Medical Dialogues

1 code implementation1 Sep 2021 Guojun Yan, Jiahuan Pei, Pengjie Ren, Zhaochun Ren, Xin Xin, Huasheng Liang, Maarten de Rijke, Zhumin Chen

(1) there is no dataset with large-scale medical dialogues that covers multiple medical services and contains fine-grained medical labels (i. e., intents, actions, slots, values), and (2) there is no set of established benchmarks for MDSs for multi-domain, multi-service medical dialogues.

A Cooperative Memory Network for Personalized Task-oriented Dialogue Systems with Incomplete User Profiles

1 code implementation16 Feb 2021 Jiahuan Pei, Pengjie Ren, Maarten de Rijke

We find that CoMemNN is able to enrich user profiles effectively, which results in an improvement of 3. 06% in terms of response selection accuracy compared to state-of-the-art methods.

Retrospective and Prospective Mixture-of-Generators for Task-oriented Dialogue Response Generation

2 code implementations19 Nov 2019 Jiahuan Pei, Pengjie Ren, Christof Monz, Maarten de Rijke

We propose a novel mixture-of-generators network (MoGNet) for DRG, where we assume that each token of a response is drawn from a mixture of distributions.

A Modular Task-oriented Dialogue System Using a Neural Mixture-of-Experts

1 code implementation10 Jul 2019 Jiahuan Pei, Pengjie Ren, Maarten de Rijke

We propose a neural Modular Task-oriented Dialogue System(MTDS) framework, in which a few expert bots are combined to generate the response for a given dialogue context.

SEntNet: Source-aware Recurrent Entity Network for Dialogue Response Selection

no code implementations16 Jun 2019 Jiahuan Pei, Arent Stienstra, Julia Kiseleva, Maarten de Rijke

Obtaining key information from a complex, long dialogue context is challenging, especially when different sources of information are available, e. g., the user's utterances, the system's responses, and results retrieved from a knowledge base (KB).
