I calculate the weights the same way as described in the … WebFeb 25, 2024 · The implementation works for classification (binary of multi class), not for multi-label classification. In multi-label classification, a sample can have more than one category. For instance, for 5 classes, a target for a sample x could be target_x = [1, 0, 1, 0, 0] # then for 64 samples, the targets are [64, 5] not [64] # I'm using 134 categories
