Class 3: Bodyweight So, reader, I left myself a day's rest in-between classes and thought that would be enough. Parameters class_weight dict, ‘balanced’ or None If ‘balanced’, class weights will be given by n_samples / (n_classes * np.bincount(y)). When imbalance in classes is measured by orders of magnitude, it's not very helpful to assign weights like 100. Allart all class … That’s a neat solution as well… I ended up changing my loss function again to NLLLoss, which supports class weights, and it’s probably the easiest native solution. Come and join us on Zoom. Class E1 weights are intended to ensure traceability between national mass standards and weights of a lower accuracy class.
