Table 6 Reevaluating RaVAEn. The final change predictions were derived by using \(\min ()\) on the change predictions from the memory. In RaVAEn-Floods, the geo-index used was NDWI; in RaVAEn-Wildfires, the NBR; and in RaVAEn-Landslides and RaVAEn-Hurricanes, NDVI. Highlighted are the best scores for STTORM-CD and RaVAEn models for each metric. All values of the evaluation metrics are reported as percentages.
