In today's lecture about advancements in artificial intelligence, the professor highlighted several breakthroughs that are shaping the field. He mentioned that one of the most significant developments is the creation of neural networks that mimic human brain functions. Neural networks have led to improvements in OCR (optical character recognition) systems, which are now able to read handwriting with much higher accuracy than before. The professor also discussed the role of AI in healthcare, emphasizing how machine learning is transforming diagnostics by allowing systems to analyze medical images and predict diseases faster than human experts. Finally, he addressed ethical concerns, indicating that as AI systems evolve, it is crucial to manage their impact on society and employment.
