S2FT: Parameter-Efficient Fine-Tuning in Sparse Spectrum Domain

CVPR 2026

Parameter Efficient Fine-Tuning (PEFT) is a key technique for adapting a large pretrained model to downstream tasks by fine-tuning only a small number of parameters. Recent methods based on Fourier transforms have further reduced the fine-tuned parameters scale by only fine-tuning a few spectral coe

AsyncDSB: Schedule-Asynchronous Diffusion Schrödinger Bridge for Image Inpainting

AAAI 2025technical

Image inpainting is an important image generation task, which aims to restore corrupted image from partial visible area. Recently, diffusion Schrödinger bridge methods effectively tackle this task by modeling the translation between corrupted and target images as a diffusion Schrödinger bridge proce…

FashionSAP: Symbols and Attributes Prompt for Fine-Grained Fashion Vision-Language Pre-Training

CVPR 2023poster

Fashion vision-language pre-training models have shown efficacy for a wide range of downstream tasks. However, general vision-language pre-training models pay less attention to fine-grained domain features, while these features are important in distinguishing the specific domain tasks from general t…

Multi-hop Graph Convolutional Network with High-order Chebyshev Approximation for Text Reasoning

ACL 2021long

Graph convolutional network (GCN) has become popular in various natural language processing (NLP) tasks with its superiority in long-term and non-consecutive word interactions. However, existing single-hop graph reasoning in GCN may miss some important non-consecutive dependencies. In this study, we…

Prototype Completion With Primitive Knowledge for Few-Shot Learning

CVPR 2021poster

Few-shot learning is a challenging task, which aims to learn a classifier for novel classes with few examples. Pre-training based meta-learning methods effectively tackle the problem by pre-training a feature extractor and then fine-tuning it through the nearest centroid based meta-learning. However…
