Researchers are training AI to interpret animal emotions

The Intellipig system, developed by researchers from the University of Bristol in western England and Scotland's Rural College, analyzes pig photos and alerts farmers to signs of pain, illness, or emotional distress.

A team from the University of Haifa, which developed facial recognition software already used to find lost dogs, is now training AI to recognize signs of discomfort on faces that are 38% similar to human facial movements.

These systems rely on humans who perform the initial work of defining the meaning of various animal behavior patterns. A researcher from the University of São Paulo conducted an experiment using photos of horse muzzles before and after surgery, as well as before and after receiving painkillers, training the AI system to focus on their eyes, ears, and mouths. The system was able to independently identify which signs could indicate pain with 88% accuracy.
