Table 3 Model performance on CoREMOF dataset. Root-mean-square-deviation (RMSD) and coefficient of determination (R\(^2\) score) results in predicting the Henry’s coefficient (log k\(_{H}\)) for CO\(_{2}\) and CH\(_{4}\) and gas uptakes for CH\(_{4}\) for the CoREMOF dataset. Different sets of features (S = baseline structural, T = topological, T + WE = topological and word embeddings) are shown.
Target | RMSD | R\(^2\) score | ||||||
