How to add a L2 regularization term in my loss function

WebOct 8, 2024 · In the case of L2 regularization we add this lamdba∗wlamdba∗ w to the gradients then compute a moving average of the gradients and their squares before using both of them for the update. Whereas the weight decay method simply consists in doing the update, then subtract to each weight. Webvars = tf.trainable_variables() lossL2 = tf.add_n([ tf.nn.l2_loss(v) for v in vars ]) * 0.001 This basically sums the l2_loss of all your trainable variables. You could also make a dictionary where you specify only the variables you want to add to your cost and use the second line above.

WebMar 21, 2024 · Introduce and tune L2 regularization for both logistic and neural network models. Remember that L2 amounts to adding a penalty on the norm of the weights to the loss. In TensorFlow, you can compute the L2 loss for a tensor t using nn.l2_loss (t). The right amount of regularization should improve your validation / test accuracy. 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().. I also see @fchollet's comment that …
