Classification mixing problem after using PCA

[MCG]

Similar problem when doing RF classification

Multi-temporal Random Forest - NaN pixels

The confidence level of the NaN is 1 so I cannot play with the threshold. If the NaN cannot be classified according to the RF algorithm, why do they have a class (they are classified as bere soil). The statistics of the output are affected and there is a dedicated class (-1) for no data. [image] [image]
