Differentially Private Fine-Tuning of Diffusion Models

ICCV 2025poster

Generative AI models, particularly diffusion models (DMs), have demonstrated exceptional capabilities in high-quality image synthesis. However, their large memorization capacity raises significant privacy concerns, especially when trained on sensitive datasets. This paper introduces DP-LoRA, a surpr…

DiffAR: Adaptive Conditional Diffusion Model for Temporal-augmented Human Activity Recognition

IJCAI 2023poster

Human activity recognition (HAR) is a fundamental sensing and analysis technique that supports diverse applications, such as smart homes and healthcare. In device-free and non-intrusive HAR, WiFi channel state information (CSI) captures wireless signal variations caused by human interference without…

Decoding Neural Representations of Rhythmic Sounds From Magnetoencephalography

ICASSP 2021accepted

Neuroscience studies have revealed neural processes involving rhythm perception, suggesting that brain encodes rhythmic sounds and embeds information in neural activity. In this work, we investigate how to extract rhythmic information embedded in the brain responses and to decode the original audio…
