AI/ML Enabled High‐Throughput Design and Synthesis for Energetic Molecules
Materials Genome Engineering Advances, EarlyView.Novel design methods for a special kind of functional molecules — the energetic molecules—are summarized. Both classic Machine Learning (ML) and Artificial Intelligence (AI) generative models are utilized for the high‐throughput design of these energetic molecules, and a sort of high‐energy low‐sensitivity molecules are obtained.
