Additionally, we introduce a new metric: the ring-breaking round-trip accuracy, calculated only for the "Ring" dataset. A disconnection is considered to be ring-breaking round-trip accurate when it is round-trip accurate and the number of rings in the product is higher than in predicted reactants. In this way, we consider not only whether the prediction is chemically valid but also whether it involves a ring disconnection, i.e. the reaction type we're aiming to improve the model's performance for.
