How Do Language Models Speak Languages? A Case Study on Unintended Code-Switching

ICML 2026poster

Unintended code-switching, which refers to the phenomenon where LLM unexpectedly switch languages, poses a fundamental challenge in the multilingual capabilities in LLMs. However, we still lack a mechanistic account of how this failure mode is implemented inside the model. For example, what internal…

MatchMask: Mask-Centric Generative Data Augmentation for Label-Scarce Semantic Segmentation

CVPR 2026

Current semantic segmentation models are very data-hungry and require massive costly pixel-wise human annotations. Generative data augmentation, which scales the train set using generative models, provides a potential remedy. In this paper, we propose MatchMask, a novel mask-centric generative data

STraj: Self-training for Bridging the Cross-Geography Gap in Trajectory Prediction

AAAI 2025technical

Accurate trajectory prediction has prominent significance in autonomous driving scenarios. Most existing methods predict the trajectory of an agent by learning its interaction with other agents and the map within the scenario. However, the heterogeneous distribution of these elements across differe…
