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

Specifically, the accuracy we managed to get in 30 epochs (which is the necessary time for SGD to get to 94% accuracy with a 1cycle policy) with Adam and L2 regularization was at 93.96% on average, going over 94% one time out of two. We consistently reached values between 94% and 94.25% with Adam and weight decay.

Adam算法和Learning rate decay Adam算法. Adam算法可以加快深度神经网络的训练的速度,它实际上是结合了exponentially weighted average算法和RMSprop算法,实际训练过程如下图所示: learning_rate传入初始lr值,global_step用于逐步计算衰减指数,decay_steps用于决定衰减周期,decay_rate是每次衰减的倍率,staircase若为False则是标准的指数型衰减,True时则是阶梯式的衰减方法,目的是为了在一段时间内(往往是相同的epoch内)保持相同的learning rate。 Args: learning_rate (:obj:`Union[float, tf.keras.optimizers.schedules.LearningRateSchedule]`, `optional`, defaults to 1e-3): The learning rate to use or a schedule. beta_1 (:obj:`float`, `optional`, defaults to 0.9): The beta1 parameter in Adam, which is the exponential decay rate for the 1st momentum estimates. beta_2 (:obj:`float`, `optional`, defaults to 0.999): The beta2 parameter in Adam Pytorch基础知识-学习率衰减(learning rate decay) 2019-11-17 2019-11-17 21:51:09 阅读 1K 0 学习率对整个函数模型的优化起着至关重要的作用。 Se hela listan på blog.shikoan.com 使用 tf.keras 过程中,如果要使用 learning rate decay,不要使用 tf.train.AdamOptimizer() 等 tf.train 内的优化器,因为学习率的命名不同,导致 tf.keras 中学习率衰减的函数无法使用,一般都会报错 “AttributeError: 'TFOptimizer' object has no attribute 'lr'”,这个时候即使我们对 "lr" 参数赋值,也没有办法在之后过程中 The method tf.nn.softmax_cross_entropy_with_logits() is another unique feature of tensorflow.
