COMI: Coarse-to-fine Context Compression via Marginal Information Gain

ICLR 2026poster

Large Language Models (LLMs) have demonstrated exceptional capabilities across diverse tasks. However, their deployment in long context scenarios remains hindered by computational inefficiency and information redundancy. Context compression methods address these challenges by significantly reducing…

Expert Divergence Learning for MoE-based Language Models

ICLR 2026poster

The Mixture-of-Experts (MoE) architecture is a powerful technique for scaling language models, yet it often suffers from expert homogenization, where experts learn redundant functionalities, thereby limiting MoE's full potential. To address this, we introduce Expert Divergence Learning, a novel pre-…

How to inject knowledge efficiently? Knowledge Infusion Scaling Law for Pre-training Large Language Models

EMNLP 2025

Large language models (LLMs) have attracted significant attention due to their impressive general capabilities across diverse downstream tasks. However, without domain-specific optimization, they often underperform on specialized knowledge benchmarks and even produce hallucination. Recent studies sh

Advancements in 3D Lane Detection Using LiDAR Point Clouds: From Data Collection to Model Development

ICRA 2024poster

Advanced Driver-Assistance Systems (ADAS) have successfully integrated learning-based techniques into vehicle perception and decision-making. However, their application in 3D lane detection for effective driving environment perception is hindered by the lack of comprehensive LiDAR datasets. The spar…

A Three-Stage Learning Framework for Low-Resource Knowledge-Grounded Dialogue Generation

EMNLP 2021main

Neural conversation models have shown great potentials towards generating fluent and informative responses by introducing external background knowledge. Nevertheless, it is laborious to construct such knowledge-grounded dialogues, and existing models usually perform poorly when transfer to new domai…
