TīmeklisReally though, if you wish to efficiently regularize L1 and don't need any bells and whistles, the more manual approach, akin to your first link, will be more readable. It would go like this. l1_regularization = 0. for param in model.parameters(): l1_regularization += param.abs().sum() loss = criterion(out, target) + l1_regularization Tīmeklis2024. gada 14. jūl. · Both L1 & L2 regularization is added per-layer of the Keras model. Each layer provides a kernel_regularizer parameter, which is None by default (implying that no regularization is applied by default).
