Micro-Macro Retrieval: Reducing Long-Form Hallucination in Large Language Models

ICLR 2026poster

Large Language Models (LLMs) achieve impressive performance across many tasks but remain prone to hallucination, especially in long-form generation where redundant retrieved contexts and lengthy reasoning chains amplify factual errors. Recent studies highlight a critical phenomenon: the closer key i…

Pusa V1.0: Unlocking Temporal Control in Pretrained Video Diffusion Models via Vectorized Timestep Adaptation

ICLR 2026poster

The rapid advancement of video diffusion models has been hindered by fundamental limitations in temporal modeling, particularly the rigid synchronization of frame evolution imposed by conventional scalar timestep variables. While task-specific adaptations and autoregressive models have sought to add…

AIMMerging: Adaptive Iterative Model Merging Using Training Trajectories for Language Model Continual Learning

EMNLP 2025

Continual learning (CL) is essential for deploying large language models (LLMs) in dynamic real-world environments without the need for costly retraining. Recent model merging-based methods have attracted significant attention, but they still struggle to effectively manage the trade-off between lear

Ambiguity Awareness Optimization: Towards Semantic Disambiguation for Direct Preference Optimization

EMNLP 2025

Direct Preference Optimization (DPO) is a widely used reinforcement learning from human feedback (RLHF) method across various domains. The study of token importance has attracted widespread attention in DPO. Researchers have found that token importance is crucial for improving the effectiveness of D

Crab: A Unified Audio-Visual Scene Understanding Model with Explicit Cooperation

CVPR 2025poster

In recent years, numerous tasks have been proposed to encourage model to develop specified capability in understanding audio-visual scene, primarily categorized into temporal localization, spatial localization, spatio-temporal reasoning, and pixel-level understanding. Instead, human possesses a unif…

Public Opinion Field Effect and Hawkes Process Join Hands for Information Popularity Prediction

AAAI 2025technical

Information popularity prediction, aiming to predict the growth of user participation in a trending topic diffusion, is a fundamental task in social networks. Existing methods often treat information diffusion as a single independent process, ignoring the ``public opinion field effect'' where multip…
