Effect of undersampling (sampled 3 stations, prediction after 3 hours).
| | w/o undersampling | w/undersampling | | -NN (min) | -VNN (min) | SVM (min) | -NN (sec) | -VNN (sec) | SVM (sec) |
| w/o normalization | 0.000 (3323) | 0.000 (3760) | N/A (>10000000) | 0.003 (301) | 0.014 (329) | 0.024 (285) | w/normalization | 0.000 (3721) | 0.000 (3940) | N/A (>10000000) | 0.032 (329) | 0.094 (349) | 0.267 (506) |
