Class imbalance in filtered_cache_... #32

Problem

not given to the model ➡️ understandable that the model does not well on these patches

According to Statistics of number of classes present on patches, there are less patches with spill maybe due to the fact that several spill polygons can be on the same image

But according to Compared with original polygons statistics, there are 196 spill and 533 seep on all rasters

After computing another time the classes stats on the new filtered cache we observe a more balanced dataset regarding seep and spill classes repartition: seep_only spill_only seep_spill
11766 9258 208
55 % 44 % 0.98 %
