The past decade has seen a sharp increase in machine learning (ML) applications in scientific research.
This review introduces the basic constituents of ML, including databases, features, and algorithms, and
highlights a few important achievements in chemistry that have been aided by ML techniques. The
described databases include some of the most popular chemical databases for molecules and materials
obtained from either experiments or computational calculations. Important two-dimensional (2D) and
three-dimensional (3D) features representing the chemical environment of molecules and solids are
briefly introduced. Decision tree and deep learning neural network algorithms are overviewed to emphasize their frameworks and typical application scenarios. Three important fields of ML in chemistry are
discussed:
- Retrosynthesis, in which ML predicts the likely routes of organic synthesis;
- Atomic simulations, which utilize the ML potential to accelerate potential energy surface sampling;
- Heterogeneous catalysis, in which ML assists in various aspects of catalytic design, ranging from synthetic condition optimization to reaction mechanism exploration. Finally, a prospect on future ML applications is provided.
