John Hopfield: Physics View of the Mind and Neurobiology | Lex Fridman Podcast #76
发布时间 2020-02-29 16:15:45 来源
摘要
John Hopfield is professor at Princeton, whose life's work weaved beautifully through biology, chemistry, neuroscience, and physics. Most crucially, he saw the messy world of biology through the piercing eyes of a physicist. He is perhaps best known for his work on associate neural networks, now known as Hopfield networks that were one of the early ideas that catalyzed the development of the modern field of deep learning.
