LLMs and Human Brains Share Emotional Valence Axis

Researchers have developed a method to map the emotional valence of human brain activity onto large language models. By creating a "V-axis" from LLM representations of emotions, they found this axis aligns with neural activity in human EEG data. While this alignment is strong, standard alignment techniques did not improve the LLMs' ability to decode emotions, leading to the discovery of a "saturation regularity" where further supervision distorts existing representations. AI

IMPACT Suggests LLMs may capture fundamental aspects of human emotional processing, potentially informing future AI alignment and cognitive science research.
