Before revision:  In this perspective, we present major applications of AI in drug discovery and discuss the relevant AI techniques, covering most recent progress in AI-driven drug discovery  .
After revision:  In this perspective, we present major applications of AI in drug discovery and discuss related applications, which can be reduced to two major tasks, i.e., molecular property prediction and molecule generation. We then discuss common data resources, molecule representations and benchmark platforms. Furthermore, to summarize the progress in AI-driven drug discovery .
