When to Think, When to Speak: Learning Disclosure Policies for Large Language Model Reasoning

ICML 2026poster

Standard Chain-of-Thought (CoT) reasoning trades reliability for responsiveness: in a single user-visible token stream, more deliberation delays meaningful output, imposing a ``silence tax.'' We introduce \emph{Side-by-Side (SxS) Interleaved Reasoning}, a training framework that makes \emph{disclosu…

The Law of Knowledge Overshadowing: Towards Understanding, Predicting and Preventing LLM Hallucination

ACL 2025finding

Hallucination is a persistent challenge in large language models (LLMs), where even with rigorous quality control, models often generate distorted facts. This paradox, in which error generation continues despite high-quality training data, calls for a deeper understanding of the underlying LLM mecha…

EVEDIT: Event-based Knowledge Editing for Deterministic Knowledge Propagation

EMNLP 2024main

The dynamic nature of real-world information necessitates knowledge editing (KE) in large language models (LLMs). The edited knowledge should propagate and facilitate the deduction of new information based on existing model knowledge. We term the existing related knowledge in LLM serving as the orig…

MuChin: A Chinese Colloquial Description Benchmark for Evaluating Language Models in the Field of Music

IJCAI 2024poster

The rapidly evolving multimodal Large Language Models (LLMs) urgently require new benchmarks to uniformly evaluate their performance on understanding and textually describing music. However, due to semantic gaps between Music Information Retrieval (MIR) algorithms and human understanding, discrepanc…

Why Does New Knowledge Create Messy Ripple Effects in LLMs?

EMNLP 2024main

Extensive previous research has focused on post-training knowledge editing (KE) for language models (LMs) to ensure that knowledge remains accurate and up-to-date. One desired property and open question in KE is to let edited LMs correctly handle ripple effects, where LM is expected to answer its lo…

Unlearning Bias in Language Models by Partitioning Gradients

ACL 2023findings

Recent research has shown that large-scale pretrained language models, specifically transformers, tend to exhibit issues relating to racism, sexism, religion bias, and toxicity in general. Unfortunately, these pretrained language models are used almost universally in downstream tasks, and natural la…

RESIN-11: Schema-guided Event Prediction for 11 Newsworthy Scenarios

NAACL 2022system demonstrations

We introduce RESIN-11, a new schema-guided event extraction&prediction framework that can be applied to a large variety of newsworthy scenarios. The framework consists of two parts: (1) an open-domain end-to-end multimedia multilingual information extraction system with weak-supervision and zero-sho…

Tracking of Enriched Dialog States for Flexible Conversational Information Access

ICASSP 2018accepted

Dialog state tracking (DST) is a crucial component in a task-oriented dialog system for conversational information access. A common practice in current dialog systems is to define the dialog state by a set of slot-value pairs. Such representation of dialog states and the slot-filling based DST have…
