RhythmFormer: Extracting rPPG Signals Based on Hierarchical Temporal Periodic Transformer

1 code implementation20 Feb 2024 Bochao Zou, Zizheng Guo, Jiansheng Chen, Huimin Ma

Due to the periodicity nature of rPPG, the long-range dependency capturing capacity of the Transformer was assumed to be advantageous for such signals.

DomainStudio: Fine-Tuning Diffusion Models for Domain-Driven Image Generation using Limited Data

no code implementations25 Jun 2023 Jingyuan Zhu, Huimin Ma, Jiansheng Chen, Jian Yuan

Typical diffusion models and modern large-scale conditional generative models like text-to-image generative models are vulnerable to overfitting when fine-tuned on extremely limited data.

Defending Against Universal Adversarial Patches by Clipping Feature Norms

no code implementations ICCV 2021 Cheng Yu, Jiansheng Chen, Youze Xue, Yuyang Liu, Weitao Wan, Jiayu Bao, Huimin Ma

Physical-world adversarial attacks based on universal adversarial patches have been proved to be able to mislead deep convolutional neural networks (CNNs), exposing the vulnerability of real-world visual classification systems based on CNNs.

Teacher-Critical Training Strategies for Image Captioning

no code implementations30 Sep 2020 Yiqing Huang, Jiansheng Chen

To effectively learn from the teacher model, we propose Teacher-Critical Training Strategies (TCTS) for both XE and RL training to facilitate better learning processes for the caption model.
