This application belongs to the goal-directed graph generation task which we mentioned in Lec 15.1. Here, we want to generate valid and realistic molecules with optimized property scores. We introduce Graph Convolutional Neural Networks (GCPN) as a solution to the task. The idea of GCPN is to generative desirable graphs via reinforcement learning, where the reward is defined by the goal of graph generation, and the policy network is parametrized as a Graph Neural Network (GNN). We compare the differences between GCPN and GraphRNN. GCPN is able to generate molecules with high drug-likeness score, which reveals a new direction for in-silico drug discovery.
