Finding the Translation Switch: Discovering and Exploiting the Task-Initiation Features in LLMs

AAAI 2026technical

Large Language Models (LLMs) frequently exhibit strong translation abilities, even without task-specific fine-tuning. However, the internal mechanisms governing this innate capability remain largely opaque. To demystify this process, we leverage Sparse Autoencoders (SAEs) and introduce a novel frame

GroundingSuite: Measuring Complex Multi-Granular Pixel Grounding

ICCV 2025poster

Pixel grounding, encompassing tasks such as Referring Expression Segmentation (RES), has garnered considerable attention due to its potential for bridging the gap between vision and language modalities. However, advancements in this domain are currently constrained by limitations inherent in existin…

Learning Cross-Modal Affinity for Referring Video Object Segmentation Targeting Limited Samples

ICCV 2023poster

Referring video object segmentation (RVOS), as a supervised learning task, relies on sufficient annotated data for a given scene. However, in more realistic scenarios, only minimal annotations are available for a new scene, which poses significant challenges to existing RVOS methods. With this in mi…

Data Poisoning Attacks against MRMR

ICASSP 2019accepted

Many machine learning models lack the consideration that an adversary can alter data at the time of training or testing. Over the past decade, the machine learning models' vulnerability has been a concern and more secure algorithms are needed. Unfortunately, the security of feature selection (FS) re…
