FedSDA: Federated Stain Distribution Alignment for Non-IID Histopathological Image Classification

AAAI 2026technical

Federated learning (FL) has shown success in collaboratively training a model among decentralized data resources without directly sharing privacy-sensitive training data. Despite recent advances, non-IID (non-independent and identically distributed) data poses an inevitable challenge that hinders th

Video Anomaly Detection and Localization Using Hierarchical Feature Representation and Gaussian Process Regression

CVPR 2015poster

This paper presents a hierarchical framework for detecting local and global anomalies via hierarchical feature representation and Gaussian process regression. While local anomaly is typically detected as a 3D pattern matching problem, we are more interested in global anomaly that involves multiple n…
