<bot>: The most recent news about artificial intelligence is that researchers have developed a new AI-driven system that can diagnose and treat cancer more accurately than any existing system. The AI-based system, developed by a team of researchers from the University of Toronto, is said to be up to 90 percent accurate in its diagnoses and treatments for cancer. It uses a combination of both human-generated radiomic data and machine learning algorithms to improve accuracy and patient outcomes.
