WebAug 13, 2024 · @scotthuang1989 I think you are right. tf's add_loss() adds regularization loss to GraphKeys.REGULARIZATION_LOSSES, but keras' add_loss() doesn't. So tf.losses.get_regularization_loss() works for tf layer but not keras layer. For keras layer, you should call layer._losses or layer.get_losses_for()..

Troubleshooting. Step 2: Check that variable counts, names, and shapes match. Troubleshooting. Step 3: Reset all variables, check numerical equivalence with all randomness disabled.
WebThe standard library uses various well-known names to collect and retrieve values associated with a graph. For example, the tf.Optimizer subclasses default to optimizing the variables collected under tf.GraphKeys.TRAINABLE_VARIABLES if none is specified, but it is also possible to pass an explicit list of variables. The following standard keys ... WebGraphKeys. REGULARIZATION_LOSSES)) cost = tf. reduce_sum (tf. abs (tf. subtract (pred, y))) +reg_losses. Conclusion. The performance of the model depends so much on other parameters, especially learning rate and epochs, and of course the number of hidden layers. Using a not-so good model, I compared L1 and L2 performance, and L2 scores …

WebJul 17, 2024 · L1 and L2 Regularization. Regularization is a technique intended to discourage the complexity of a model by penalizing the loss function. Regularization assumes that simpler models are better for generalization, and thus better on unseen test data.
