Representation as an Euler diagram of the domain of a RNN trained with SMILES strings. The sets are the following, ordered by their size: All possible strings generated by an RNN (red), all possible valid SMILES (yellow), all possible SMILES of GDB-13 molecules (light blue), all canonical SMILES of GDB-13 molecules (dark blue) and the training set (black). Note that the relative sizes of the different subsets do not reflect their true size
