Table depicts the performance of various modules in our model. Regardless of the reaction types are unknown or known, the prediction of Bond type change, Bond type, and Topological completeness all exceed 98% in the accuracy. This implies that the overall accuracy of HGAR is primarily determined by Reaction center and Motif prediction. Additionally, there is a substantial improvement in the Reaction center prediction from "Unknown" to "Known", which suggests that the position of the reaction center plays a significant role in determining the reaction type.
