Ah it’s interesting how you make the learning rate scheduler first in TensorFlow, then pass it into your optimizer. In PyTorch, we first make the optimizer: my_model = torchvision.models.resnet50() my_optim = torch.optim.Adam(params=my_model.params, lr=0.001, betas=(0.9, 0.999), eps=1e-08, weight_decay=0, amsgrad=False) You can use a learning rate schedule to modulate how the learning rate of your optimizer changes over time: lr_schedule = keras . optimizers . schedules . ExponentialDecay ( initial_learning_rate = 1e-2 , decay_steps = 10000 , decay_rate = 0.9 ) optimizer = keras . optimizers . Common learning rate schedules include time-based decay, step decay and exponential decay.

2. tf.train.exponential_decay 사용법. There is absolutely no reason why Adam and learning rate decay can't be used together. Note that in the paper they use the standard decay tricks for proof of convergence.

Allowed to be {clipnorm, clipvalue, lr, decay}. clipnorm is clip gradients by norm; clipvalue is clip gradients by value, decay is included for backward compatibility to allow time inverse decay of learning rate. lr is included for backward compatibility, recommended to use learning_rate instead.

Momentum decay (beta1) is also applied to the entire momentum accumulator. This means that the sparse behavior is equivalent to the dense behavior (in contrast to some momentum implementations which ignore momentum unless a variable slice was actually used). Args: learning_rate: A Tensor or a floating point value. The learning rate. tf.keras.optimizers.Adam, When training a model, it is often recommended to lower the learning rate as the training progresses.

decay of the world has started; it is finally made visible and it is going on by a pace quite.

If you don't want to try that, then you can switch from Adam to SGD with decay in the middle of learning, as done for example in … 2018-10-16 Hello, I am waiting to use some modified DeepSpeech code on a GPU and wanted to know if anyone has implemented learning rate decay to the Adam Optimizer already before I begin training. Does anyone have reasons they wouldn’t want to do this? My code block is below. This would likely change the best starting point to a much higher learning rate but might also help me avoid early stopping I am trying to implement an exponential learning rate decay with the Adam optimizer for a LSTM. I do not want the 'staircase = true' version. The decay_steps for me feels like the number of steps that the learning rate keeps constant. But I am not sure about this and Tensorflow has not stated it in their documentation.
