Contributed by Johannes Hachmann

In this tutorial review, von Lilienfeld gives an insightful overview of his group’s efforts to enumerate and explore chemical compound space. The author addresses a number of topics and strategies his group uses to assess the quantum chemical properties of molecules in a well-defined domain of chemical space including their mutual relationships. The last part of the discussion covering machine learning approaches to developing an understanding of structure-property relationships is particularly interesting. In this part of the tutorial, the author discusses his group’s pioneering work towards recovering the mapping between a molecular structure and its (quantum mechanical) properties - which is rigorously provided by the Schrödinger equation - via a supervised machine learning approach. He gives a practical recipe for this scheme, including a discussion of his Coulomb matrix descriptor. This tutorial is a valuable contribution to facilitating a better understanding of this exciting new research area.
