Before revision:  In our experiments, MONSTOR achieves near-perfect accuracy on unseen real social networkswith little sacrifice of accuracy in IM use cases.
After revision:  In our experiments, MONSTOR provided highly accurate estimates, achieving 0.998 or higher Pearson and Spearman correlation coefficients in unseen real-world social networks. Moreover, IM algorithms equipped with MONSTOR are more accurate than state-of-the-art competitors in 67\% of IM use cases.
