Recently, Leifeng.com's "Medical AI Nuggets" with the theme of "AI Pharmaceutical·The Next Phenomenon Track" invited Baitu Biosciences, Jitai Pharmaceutical, Unknown Jun, Wangshi Wisdom, Yingxi Intelligent, Xingyao Six pioneering companies in science and technology held an online cloud summit. Li Chengtao said that in summary, AI pharmacy mainly includes two types of problems. The first is classification and regression, to know exactly what the properties of a new molecule are, and the second is generation and design to find out which are good molecules and those that are bad. .
