Performance of the extremely randomized trees ML algorithm in predicting UG and UV H2 capacities of MOFs under PS and TPS conditions
H2 capacity type | R2 | AUE (capacity units) | RMSE (capacity units) | Kendall τ | MAE (capacity units) |
---|---|---|---|---|---|
UG at PS (wt %) | 0.997 | 0.14 | 0.18 | 0.961 | 0.10 |
UV at PS (g-H2 L−1) | 0.984 | 0.97 | 1.40 | 0.922 | 0.69 |
UG at TPS (wt %) | 0.997 | 0.16 | 0.23 | 0.966 | 0.10 |
UV at TPS (g-H2 L−1) | 0.967 | 1.32 | 1.92 | 0.819 | 0.91 |
R2, AUE, RSME, and MAE represent the coefficient of determination, average unsigned error, root-mean-squared error, and median absolute error, respectively.
