A Theoretical Analysis of Detecting Large Model-Generated Time Series

AAAI 2026technical

Motivated by the increasing risks of data misuse and fabrication, we investigate the problem of identifying synthetic time series generated by Time-Series Large Models (TSLMs) in this work. While there are extensive researches on detecting model generated text, we find that these existing methods ar

The Knowledge Alignment Problem: Bridging Human and External Knowledge for Large Language Models

ACL 2024findings

Large language models often necessitate grounding on external knowledge to generate faithful and reliable answers. Yet even with the correct groundings in the reference, they can ignore them and rely on wrong groundings or their inherent biases to hallucinate when users, being largely unaware of the…

Multi-Action Dialog Policy Learning from Logged User Feedback

AAAI 2023technical

Multi-action dialog policy (MADP), which generates multiple atomic dialog actions per turn, has been widely applied in task-oriented dialog systems to provide expressive and efficient system responses. Existing MADP models usually imitate action combinations from the labeled multi-action dialog samp…

“Think Before You Speak”: Improving Multi-Action Dialog Policy by Planning Single-Action Dialogs

IJCAI 2022poster

Multi-action dialog policy (MADP), which generates multiple atomic dialog actions per turn, has been widely applied in task-oriented dialog systems to provide expressive and efficient system responses. Existing MADP models usually imitate action combinations from the labeled multi-action dialog samp…

Learning to Check Contract Inconsistencies

AAAI 2021technical

Contract consistency is important in ensuring the legal validity of the contract. In many scenarios, a contract is written by filling the blanks in a precompiled form. Due to carelessness, two blanks that should be filled with the same (or different) content may be incorrectly filled with different…
