I am a research asistant at The Chinese University of Hong Kong (CUHK). I am interested in physic-informed machine learning, trustworthy AI, and reinforcement learning (sometimes plays with distributed system). My goal is to build a reliable AI system that can be impact the real world massively.

I received Bachelor's degree in Computer Science from National Tsing Hua University (NTHU). Before graduate, I was also a research assistant at DataLab and advised by Prof. Shan-Hung Wu. It's my pleasure to work with Dr. Pin-Yu Chen and Prof. Tsung-Yi Ho after graduate.

Happy to chat~ If you have anything want to talk or help, please book a time slot through this link.

VillanDiffusion: A Unified Backdoor Attack Framework for Diffusion Models
Sheng-Yen Chou, Pin-Yu Chen, Tsung-Yi Ho
NeurIPS 2023, NeurIPS 2023 BUGS Workshop Oral
Paper

Proposed a backdoor attack on the diffusion models with broader settings, including score-based models, various samplers, and text triggers.

How to Backdoor Diffusion Models?
Sheng-Yen Chou, Pin-Yu Chen, Tsung-Yi Ho
CVPR 2023, ICLR 2023 BANDS Workshop Best Paper Award
Paper

Proposed a new backdoor attack on the diffusion models. We found that the attacker can embed a backdoor into the diffusion models with 5% poison rate and 50 epoch fine-tuning.

Elijah: Eliminating Backdoors Injected in Diffusion Models via Distribution Shift
Shengwei An, Sheng-Yen Chou, Kaiyuan Zhang, Qiuling Xu, Guanhong Tao, Guangyu Shen, Siyuan Cheng, Shiqing Ma, Pin-Yu Chen, Tsung-Yi Ho, Xiangyu Zhang
AAAI 2024, NeurIPS 2023 BUGS Workshop
Paper

Proposed backdoor detection and removal algorithms for backdoor diffusion models.

Rethinking Backdoor Attacks on Dataset Distillation: A Kernel Method Perspective
Ming-Yu Chung, Sheng-Yen Chou, Chia-Mu Yu, Pin-Yu Chen, Sy-Yen Kuo, Tsung-Yi Ho
ICLR 2024
Paper

Proposed a computational-effiecient backdoor attack on data distillation based on NTK theory.

Single-level Adversarial Data Synthesis based on Neural Tangent Kernels
Yu-Rong Zhang, Ruei-Yang Su, Sheng-Yen Chou, Shan-Hung Wu
ArXiv Preprint
Paper

Proposed a new generative model that reduce the bilevel optimization objective into single-level one while keeping the spirit of adversarial learning. Our method takes NTK-GP as the surrogate of the discriminator and generate comparable images with SOTA GANs.
