An AI system can diagnose childhood diseases better than some doctors (1 minute read)
A medical center in China has developed an AI system that was better than junior doctors in diagnosing a range of illnesses in children. The system was able to diagnose diseases with 90-97% accuracy. While junior doctors were less accurate in diagnosing illnesses than the AI system, senior doctors were able to to diagnoses illnesses at a much higher success rate.
