# tf.keras.optimizers.Adam, When training a model, it is often recommended to lower the learning rate as the training progresses. This schedule applies an exponential The ⍺ refers to the learning rate which controls the update of the network weights. J (θ) is called the loss function.

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. 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 Google's NMT paper.

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.

## Learning rate decay / scheduling 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.SGD(learning_rate=lr_schedule) Learning rate in TensorFlow

upon implementing momentum (set to 0.5), with a starting learning rate of 1.0 and a decay of 1e-3. Optimizer: Adam. 2020年1月11日 Learning rate is scheduled to be reduced after 20, 30 epochs.

### 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 .

learning_rate: float. Learning rate. beta1: float.

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.

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. Any help is much appreciated. Args: learning_rate (:obj:`Union[float, tf.keras.optimizers.schedules.LearningRateSchedule]`, `optional`, defaults to 1e-3): The learning rate to use or a schedule.

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?

### It requires a step value to compute the decayed learning rate. You can just pass a TensorFlow variable that you increment at each training step. The schedule is a 1-arg callable that produces a decayed learning rate when passed the current optimizer step.

decayed_learning_rate = learning_rate * decay_rate ^ (global_step / decay_steps) 1. 2. 这个代码可以看一下 learning_rate 的变化趋势：.
