AI Learns to See Beyond Labels

December 20, 2025 by BBG News

Open ad-hoc categorization dynamically adapts to user needs by holistically reasoning over both labeled and unlabeled images, enabling the inference of novel concepts and the propagation of labels even across previously unseen classes, a capability extending beyond generalized category discovery through contextual adaptation.

A new approach allows artificial intelligence to categorize images and objects even with limited training data and changing contexts.

Understanding Cattle Social Dynamics Through Behavior

December 20, 2025 by BBG News

The system simultaneously estimates individual cow actions, such as standing, and rarer dyadic interactions like mounting, by leveraging a shared latent space to model both behaviors from single-image observations.

A new framework, CattleAct, enhances the detection of nuanced cattle interactions by focusing on the relationship between individual actions and collective behavior.
