Invited Speech on AI by Professor Hong Yan to Gifted Students

Professor Hong Yan delivered an invited speech on “Artificial Intelligence: History, Current Status, and Future Opportunities and Challenges” to over 100 gifted high school students. He provided a review of the historical development of AI-related technologies, including reasoning, optimization, expert systems, multi-layer perceptrons and deep learning, and their applications to natural language processing, speech and image pattern recognition, computer vision, and decision making. Professor Yan shared his experience learning LISP and solving the blocks world problem from his student’s time. Besides, he also presented his groups’ current work on object tracking and recognition, co-clustering, tensor computing, cell imaging, and analysis of lung cancer drug resistance.

Professor Yan pointed out that current methods in AI, especially for deep learning, can be used to solve a wide range of real-world problems. However, there are also many challenges ahead. He showed an interesting example of recognizing the number “8” with different shapes and styles. It is infeasible to collect enough training samples for all these variations using the current data fitting-based classifier design methodologies. He encouraged students to gain knowledge in related areas, such as mathematics, computer science, psychology, and neuroscience, have a good understanding of basic principles, not to shy away from complex problems, go beyond existing technologies, and develop radically new ones.
