AsianFin -- Artificial intelligence may one day help humans understand when animals are in pain or experiencing emotions, according to researchers recently profiled in Science.
One example is the Intellipig system, developed by scientists at the University of the West of England Bristol and Scotland’s Rural College. The system analyzes photos of pigs’ faces and alerts farmers to signs of pain, illness, or emotional distress.
Similarly, a team at the University of Haifa—known for its facial recognition software that helps locate lost dogs—is training AI to detect discomfort in dogs' faces. Their research builds on findings that dogs share 38% of facial movements with humans.
Most of these AI systems require human researchers to first classify animal behaviors. However, a recent study from the University of São Paulo took a different approach. By training AI on images of horses’ faces before and after surgery, as well as before and after receiving painkillers, researchers found that the system could independently identify pain indicators with 88% accuracy by analyzing their eyes, ears, and mouths.
