By default, the losses are averaged over each loss element in the batch. Note that for some losses, there are multiple elements per sample. WebMinimizing sum of net's weights prevents situation when network is oversensitive to particular inputs. The other cause for this situation could be bas data division into training, validation and test set. Training and validation set's loss is low - perhabs they are pretty similiar or correlated, so loss function decreases for both of them.
