Robustness with respect to the graphical depiction. There are several standards for graphically representing a molecule structure. We provide evidence that our contextual explanations are robust with respect to different graphical representations by slightly modifying the score . Let G 1 (m), G 2 (m) be two different graphical depictions of the same molecule m, then the score s G (m) = 1 2 | a(G 1 (m))a(G 2 (m))| measures the average absolute difference between two attribution maps obtained from the two different graphical methods. We computed the score across a set of 121 molecules, and we obtained an average value of E[s G ] = 0.148 ± 0.003, which reveals a high level of agreement between explanations obtained from different graphical representations. Figure shows some examples of such pictorial representations with their respective contextual explanations.
