The estimation of chemical reaction properties {such as|like|including|for example|for instance|which include} activation energies, {rates|prices} or yields {is a|is really a|is actually a|can be a|is often a|is usually a} central {topic|subject} of computational chemistry. In contrast to molecular properties, {where|exactly where} machine {learning|studying|understanding|finding out|mastering} approaches {such as|like|including|for example|for instance|which include} graph convolutional neural networks (GCNNs) have excelled {for a|to get a|for any} wide {variety|selection|assortment|range|wide variety} of tasks, no {general|common|basic} and transferable adaptations of GCNNs for reactions {have been|happen to be|have already been} {developed|created} {yet|however|but}. We {therefore|consequently|as a result|for that reason|thus|hence} combined a {popular|well-liked|well-known|common|well known|preferred} cheminformatics reaction representation, the so-called condensed graph of reaction (CGR), {with a|having a|using a} {recent|current} GCNN architecture to arrive at a versatile, robust and compact deep {learning|studying|understanding|finding out|mastering} model. The CGR {is a|is really a|is actually a|can be a|is often a|is usually a} superposition {of the|from the|in the|on the|with the|of your} reactant and {product|item|solution} graphs of a chemical reaction, and {thus|therefore|hence|as a result} {an ideal|a perfect} input for graph-based machine {learning|studying|understanding|finding out|mastering} approaches.
