We found that this small amount of weight decay was important for the model to learn. In other words, weight decay here is not merely a regularizer: it reduces the model’s training error. 2017-11-14 · We note that common implementations of adaptive gradient algorithms, such as Adam, limit the potential benefit of weight decay regularization, because the weights do not decay multiplicatively (as would be expected for standard weight decay) but by an additive constant factor. We propose a simple way to resolve this issue by decoupling weight decay and the optimization steps taken w.r.t. the The common way to introduce the weight decay w t {x} t − 1 to Adam results in an update which only distantly resembles the original weight decay given by Eq. ( 1 ) because the {v} t vectors are not only responsible for the parameter-wise amplitudes of {g} t but also for the parameter-wise amplitudes of weights {x} t . weights_var = tf.trainable_variables() gradients = tf.gradients(loss, weights_var) optimizer = tf.train.AdamOptimizer(learning_rate=deep_learning_rate) train_op = optimizer.apply_gradients(zip(gradients, weights_var)) # weight decay operation with tf.control_dependencies([train_op]): l2_loss = weight_decay * tf.add_n([tf.nn.l2_loss(v) for v in weights_var]) sgd = tf.train.GradientDescentOptimizer(learning_rate=1.0) decay_op = sgd.minimize(l2_loss) This is an implementation of the AdamW optimizer described in "Decoupled Weight Decay It computes the update step of tf.keras.optimizers.Adam and decay _adamw Adam with warm restarts and normalized weight decay (Section 4). After we ﬁx the weight decay in Adam and design AdamW, we introduce AdamWR to obtain strong anytime per-formance by performing warm restarts.

When Optimizer that implements the Adam algorithm with weight decay.

To load a pretrained model: python import timm m = timm.create_model('tf_mobilenetv3_large_075', pretrained=True) m.eval() Replace the model name with the A weight regularizer can be any callable that takes as input a weight tensor (e.g. the kernel of a Conv2D layer), and returns a scalar loss.

If it is true, perhaps it's because ADAM is relatively new and learning rate decay "best practices" haven't been established yet. I do want to note however that learning rate decay is actually part of the theoretical guarantee for ADAM. 1.weight decay.

`extend_with_decoupled_weight_decay(tf.keras.optimizers.Adam)` is: equivalent to `tfa.optimizers.AdamW`.

The basic assumption was that the weight decay can lower the oscillations of the batch loss especially present in the previous image (red learning rate). I first tried to understand the impact of weight_decay on SGD. TF works out of the box while in pytorch I could not replicate the results even when trying a whole lot of different configurations (network architectures, optimizers, etc…) Now for the experiments: I have tried to make the results as comparable as possible doing the following: A: Same hyperparameters for Adam (default ones in TF) The following are 30 code examples for showing how to use tensorflow.contrib.layers.l2_regularizer().These examples are extracted from open source projects.
