unet-efficientnet-b7-ltfl-mmgab-150ep-2window-ftw

U-Net generally conforming to the current FTW baseline 3-class model settings, trained on the Fields of the World full dataset, using both time points (Window A, Window B) for 150 epochs. The model is the same as the current FTW PRUE variant with EfficientNet-b7 backbone, but was trained using a locally-weighted Tversky Focal Loss rather Logcoshdice, and using global min-max across band normalization using the 1st and 99th percentile image values. See here for code and configuration.
