Mapping chemical performance on molecular structures using locally interpretable explanations

Understand

In this work, we present an application of Locally Interpretable Machine-Agnostic Explanations to 2-D chemical structures.

• Using this framework we are able to provide a structural interpretation for an existing black-box model for classifying biologically produced fuel compounds with regard to Research Octane Number.
• This method of "painting" locally interpretable explanations onto 2-D chemical structures replicates the chemical intuition of synthetic chemists, allowing researchers in the field to directly accept, reject, inform and evaluate decisions underlying inscrutably complex quantitative structure-activity relationship models.
