Nine Emotion Centroids: A Label-Free Valence Axis That Transfers Across Four Modalities

This work shows how to find this valence axis (V-axis) from just 9 emotion category names plus 50 short narrative paragraphs per emotion -- about 1,500 fewer labels than the usual supervised approach -- and that the same direction appears in vision, audio, and human-brain encoders never jointly trained.
