A Stronger Mixture of Low-Rank Experts for Fine-Tuning Foundation Models

ICML 2025poster

In order to streamline the fine-tuning of foundation models, Low-Rank Adapters (LoRAs) have been substantially adopted across various fields, including instruction tuning and domain adaptation. The underlying concept of LoRA involves decomposing a full-rank matrix into the product of two lower-rank…

Octopus: Alleviating Hallucination via Dynamic Contrastive Decoding

CVPR 2025highlight

Large Vision-Language Models (LVLMs) have obtained impressive performance in visual content understanding and multi-modal reasoning. Unfortunately, these large models suffer from serious hallucination problems and tend to generate fabricated responses. Recently, several Contrastive Decoding (CD) str…

Pruning All-Rounder: Rethinking and Improving Inference Efficiency for Large Vision Language Models

ICCV 2025poster

Although Large Vision-Language Models (LVLMs) have achieved impressive results, their high computational costs pose a significant barrier to wide application. To enhance inference efficiency, most existing approaches can be categorized as parameter-dependent or token-dependent strategies to reduce c…

Rethinking and Improving Visual Prompt Selection for In-Context Learning Segmentation Framework

ECCV 2024poster

"As a fundamental and extensively studied task in computer vision, image segmentation aims to locate and identify different semantic concepts at the pixel level. Recently, inspired by In-Context Learning (ICL), several generalist segmentation frameworks have been proposed, providing a promising para…

S3C: Semi-Supervised VQA Natural Language Explanation via Self-Critical Learning

CVPR 2023poster

VQA Natural Language Explanation (VQA-NLE) task aims to explain the decision-making process of VQA models in natural language. Unlike traditional attention or gradient analysis, free-text rationales can be easier to understand and gain users' trust. Existing methods mostly use post-hoc or self-ratio…

A Simple and Robust Correlation Filtering Method for Text-Based Person Search

ECCV 2022poster

"Text-based person search aims to associate pedestrian images with natural language descriptions. In this task, extracting differentiated representations and aligning them among identities and descriptions is an essential yet challenging problem. Most of the previous methods depend on additional lan…

Proposal-free One-stage Referring Expression via Grid-Word Cross-Attention

IJCAI 2021poster

Referring Expression Comprehension (REC) has become one of the most important tasks in visual reasoning, since it is an essential step for many vision-and-language tasks such as visual question answering. However, it has not been widely used in many downstream tasks because it suffers 1) two-stage m…
