Diffusion Prior Interpolation for Flexibility Real-World Face Super-Resolution

1 code implementation21 Dec 2024 Jiarui Yang, Tao Dai, Yufei Zhu, Naiqi Li, Jinmin Li, Shutao Xia

In this paper, we propose a masking strategy with strong and weak constraints and iterative refinement for real-world FSR, termed Diffusion Prior Interpolation (DPI).

EMS: Adaptive Evict-then-Merge Strategy for Head-wise KV Cache Compression Based on Global-Local Importance

no code implementations11 Dec 2024 Yingxin Li, Ye Li, Yuan Meng, Xinzhu Ma, Zihan Geng, Shutao Xia, Zhi Wang

However, these approaches often produce biased distributions of important tokens due to the influence of accumulated attention scores or positional encoding.

One Perturbation is Enough: On Generating Universal Adversarial Perturbations against Vision-Language Pre-training Models

1 code implementation8 Jun 2024 Hao Fang, Jiawei Kong, Wenbo Yu, Bin Chen, Jiawei Li, Hao Wu, Shutao Xia, Ke Xu

In this paper, we reveal that VLP models are also vulnerable to the instance-agnostic universal adversarial perturbation (UAP).

Theoretically Principled Federated Learning for Balancing Privacy and Utility

no code implementations24 May 2023 Xiaojin Zhang, Wenjie Li, Kai Chen, Shutao Xia, Qiang Yang

We propose a general learning framework for the protection mechanisms that protects privacy via distorting model parameters, which facilitates the trade-off between privacy and utility.

Contrastive Masked Autoencoders for Self-Supervised Video Hashing

1 code implementation21 Nov 2022 Yuting Wang, Jinpeng Wang, Bin Chen, Ziyun Zeng, Shutao Xia

To capture video semantic information for better hashing learning, we adopt an encoder-decoder structure to reconstruct the video from its temporal-masked frames.

PILC: Practical Image Lossless Compression with an End-to-end GPU Oriented Neural Framework

no code implementations CVPR 2022 Ning Kang, Shanzhao Qiu, Shifeng Zhang, Zhenguo Li, Shutao Xia

Generative model based image lossless compression algorithms have seen a great success in improving compression ratio.

WeClick: Weakly-Supervised Video Semantic Segmentation with Click Annotations

no code implementations7 Jul 2021 Peidong Liu, Zibin He, Xiyu Yan, Yong Jiang, Shutao Xia, Feng Zheng, Maowei Hu

In this work, we propose an effective weakly-supervised video semantic segmentation pipeline with click annotations, called WeClick, for saving laborious annotating effort by segmenting an instance of the semantic class with only a single click.

Energy Aligning for Biased Models

no code implementations7 Jun 2021 Bowen Zhao, Chen Chen, Qi Ju, Shutao Xia

Training on class-imbalanced data usually results in biased models that tend to predict samples into the majority classes, which is a common and notorious problem.

Towards a category-extended object detector with limited data

no code implementations28 Dec 2020 Bowen Zhao, Chen Chen, Xi Xiao, Shutao Xia

Object detectors are typically learned on fully-annotated training data with fixed predefined categories.

Boosting Black-Box Attack with Partially Transferred Conditional Adversarial Distribution

1 code implementation CVPR 2022 Yan Feng, Baoyuan Wu, Yanbo Fan, Li Liu, Zhifeng Li, Shutao Xia

This work studies black-box adversarial attacks against deep neural networks (DNNs), where the attacker can only access the query feedback returned by the attacked DNN model, while other information such as model parameters or the training datasets are unknown.
