MotionZero:Exploiting Motion Priors for Zero-shot Text-to-Video Generation

no code implementations28 Nov 2023 Sitong Su, Litao Guo, Lianli Gao, HengTao Shen, Jingkuan Song

To tackle the two issues, we propose a prompt-adaptive and disentangled motion control strategy coined as MotionZero, which derives motion priors from prompts of different objects by Large-Language-Models and accordingly applies motion control of different objects to corresponding regions in disentanglement.

BatchNorm-based Weakly Supervised Video Anomaly Detection

1 code implementation26 Nov 2023 Yixuan Zhou, Yi Qu, Xing Xu, Fumin Shen, Jingkuan Song, HengTao Shen

In the proposed BN-WVAD, we leverage the Divergence of Feature from Mean vector (DFM) of BatchNorm as a reliable abnormality criterion to discern potential abnormal snippets in abnormal videos.

CUCL: Codebook for Unsupervised Continual Learning

1 code implementation25 Nov 2023 Chen Cheng, Jingkuan Song, Xiaosu Zhu, Junchen Zhu, Lianli Gao, HengTao Shen

To address this issue, after analyzing the phenomenon and identifying the lack of diversity as a vital factor, we propose a method named Codebook for Unsupervised Continual Learning (CUCL) which promotes the model to learn discriminative features to complete the class boundary.

From Global to Local: Multi-scale Out-of-distribution Detection

1 code implementation20 Aug 2023 Ji Zhang, Lianli Gao, Bingguang Hao, Hao Huang, Jingkuan Song, HengTao Shen

Out-of-distribution (OOD) detection aims to detect "unknown" data whose labels have not been seen during the in-distribution (ID) training process.

ImbSAM: A Closer Look at Sharpness-Aware Minimization in Class-Imbalanced Recognition

1 code implementation ICCV 2023 Yixuan Zhou, Yi Qu, Xing Xu, HengTao Shen

To overcome this bottleneck, we leverage class priors to restrict the generalization scope of the class-agnostic SAM and propose a class-aware smoothness optimization algorithm named Imbalanced-SAM (ImbSAM).

An Efficient Membership Inference Attack for the Diffusion Model by Proximal Initialization

1 code implementation26 May 2023 Fei Kong, Jinhao Duan, RuiPeng Ma, HengTao Shen, Xiaofeng Zhu, Xiaoshuang Shi, Kaidi Xu

Therefore, we also explore the robustness of diffusion models to MIA in the text-to-speech (TTS) task, which is an audio generation task.

DETA: Denoised Task Adaptation for Few-Shot Learning

2 code implementations ICCV 2023 Ji Zhang, Lianli Gao, Xu Luo, HengTao Shen, Jingkuan Song

Test-time task adaptation in few-shot learning aims to adapt a pre-trained task-agnostic model for capturing taskspecific knowledge of the test task, rely only on few-labeled support samples.

Revisiting Multi-Codebook Quantization

no code implementations NeurIPS 2021 Xiaosu Zhu, Jingkuan Song, Lianli Gao, Xiaoyan Gu, HengTao Shen

However, finding the optimal solution to MCQ is proved to be NP-hard due to its encoding process, \textit{i. e.}, converting an input vector to a binary code.
