tf.keras.optimizers.Adam, Tensorflow provides an op to automatically apply an exponential decay to a learning rate tensor: tf.train.exponential_decay . For an example of The rate in which the learning rate is decayed is based on the parameters to the polynomial function.

optimizer.decay = tf.Variable(0.0) # Adam.__init__ assumes ``decay`` is a float object, so this needs to be converted to tf.Variable **after** __init__ method. The root problem is that Adam.__init__ will initialize variables with python float objects which will not be tracked by tensorflow.

更新公式：. 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：. Medium Se hela listan på machinelearningmastery.com 下面是一个利用 AdamW 的示例程序（TF 2.0, tf.keras），在使用 AdamW 的同时，使用 learning rate decay：（以下程序中，AdamW 的结果不如 Adam，这是因为模型比较简单，加入 regularization 反而影响性能） I am trying to implement an exponential learning rate decay with the Adam optimizer for a LSTM.

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. learning_rate: A Tensor or a floating point value. The learning rate. beta1: A float value or a constant float tensor. The exponential decay rate for the 1st moment estimates.

보통 일반적인 Stochastic gradient descent를 이용한 backprop을 할때 weight 의 learning rate를 잘 조정하는 것이 중요하다. 초기에는 이 learning rate를 grid search(요즘엔 random search를 사용하는 추세이다.)로 찾아 가장 오차를 적게하는 learning rate로 고정을 시켰다. Decays the learning rate of each parameter group by gamma every step_size epochs. Notice that such decay can happen simultaneously with other changes to the learning rate from outside this scheduler. When last_epoch=-1, sets initial lr as lr. Parameters.
