Fig. reports test-set results in R 2 for MCRT and baseline models along with performance correlation plots of MCRT across all downstream prediction tasks. From the radar plot in Fig. , MCRT scores the highest R 2 across all prediction tasks, especially in the data-scarce charge mobility (CM) dataset, where it significantly outperforms other models. Although baseline models may perform well on specific tasks, they struggle to balance performance across diverse tasks. For instance, ALIGNN excels in lattice energy prediction but shows only average performance in other areas. This further highlights the universality of MCRT.
