Groundbreaking AI can accurately decode emotions from multiple animal species

For years, scientists have tried to understand how animals express emotions. Unlike humans, they cannot describe their feelings, leaving researchers to rely on behavioral and physiological cues. However, recent advances in artificial intelligence (AI) and machine learning offer a new way to decode emotional states—through vocalizations.

A groundbreaking study led by researchers at the University of Copenhagen has taken a major step forward in this field. Using a machine-learning algorithm,…
