Generalizable Sensor-Based Activity Recognition via Categorical Concept Invariant Learning

AAAI 2025technical

Human Activity Recognition (HAR) aims to recognize activities by training models on massive sensor data. In real-world deployment, a crucial aspect of HAR that has been largely overlooked is that the test sets may have different distributions from training sets due to inter-subject variability inclu…

LOTA: Bit-Planes Guided AI-Generated Image Detection

ICCV 2025poster

The rapid advancement of GAN and Diffusion models makes it more difficult to distinguish AI-generated images from real ones. Recent studies often use image-based reconstruction errors as an important feature for determining whether an image is AI-generated. However, these approaches typically incur…
