Learn When (not) to Trust Language Models: A Privacy-Centric Adaptive Model-Aware Approach

no code implementations4 Apr 2024 Chengkai Huang, Rui Wang, Kaige Xie, Tong Yu, Lina Yao

Despite their great success, the knowledge provided by the retrieval process is not always useful for improving the model prediction, since in some samples LLMs may already be quite knowledgeable and thus be able to answer the question correctly without retrieval.

Foundation Models for Recommender Systems: A Survey and New Perspectives

no code implementations17 Feb 2024 Chengkai Huang, Tong Yu, Kaige Xie, Shuai Zhang, Lina Yao, Julian McAuley

Recently, Foundation Models (FMs), with their extensive knowledge bases and complex architectures, have offered unique opportunities within the realm of recommender systems (RSs).

Few-Shot Dialogue Summarization via Skeleton-Assisted Prompt Transfer in Prompt Tuning

no code implementations20 May 2023 Kaige Xie, Tong Yu, Haoliang Wang, Junda Wu, Handong Zhao, Ruiyi Zhang, Kanak Mahadik, Ani Nenkova, Mark Riedl

In this paper, we focus on improving the prompt transfer from dialogue state tracking to dialogue summarization and propose Skeleton-Assisted Prompt Transfer (SAPT), which leverages skeleton generation as extra supervision that functions as a medium connecting the distinct source and target task and resulting in the model's better consumption of dialogue state information.

Calibrating Trust of Multi-Hop Question Answering Systems with Decompositional Probes

no code implementations16 Apr 2022 Kaige Xie, Sarah Wiegreffe, Mark Riedl

We show that decomposition is an effective form of probing QA systems as well as a promising approach to explanation generation.

Guiding Neural Story Generation with Reader Models

no code implementations16 Dec 2021 Xiangyu Peng, Kaige Xie, Amal Alabdulkarim, Harshith Kayam, Samihan Dani, Mark O. Riedl

In this paper, we introduce Story generation with Reader Models (StoRM), a framework in which a reader model is used to reason about the story should progress.
