AI models encode Russell's emotion model, but rare classes pose geometric challenge

By PulseAugur Editorial · [3 sources] ·

Two new arXiv papers explore the geometric properties of emotion representation in AI models. The first paper demonstrates that multimodal Transformers can perfectly align with Russell's circumplex model of affect, suggesting that the model's structure is intrinsically encoded in embeddings. The second paper argues that failures in rare-class emotion recognition are due to the geometric degeneracy of these classes on the circumplex, rather than simple class imbalance, proposing that new representations are needed to distinguish these emotions. AI

IMPACT These papers suggest that while AI models can encode complex emotional structures, achieving robust recognition of rare emotions may require new representational approaches beyond current geometric or imbalance-based methods.

    The Circumplex Degeneracy Behind the Rare-Class Limit in Affect Recognition

    arXiv:2606.15763v1 Announce Type: new Abstract: In-the-wild expression recognition persistently fails on a few rare emotions, and the standard explanation is class imbalance. Through a controlled multi-task study on two benchmarks, we show the failure is instead a property of aff…
