How : (a) users have two models with similar accuracy and compare their explanations to select that which is more consistent with chemical knowledge; (b) users compare the predictions of two models and identify specific regions of the chemical space in which both models perform poorly; (c) users compare explanations from two XAI methods and identify agreements and disagreements. Use case: 2. Tools with exploratory functionalities designed for chemical spaces and molecular-representation methods can be used for the purpose of T1; tools that were not designed for chemical data, can also be used, but may limit the analysis.
