optimizer = tf.train.AdamOptimizer(learning_rate=2e-3) train_op = optimizer.apply_gradients(zip(gradients, trainable_variables)) 已经定义了训练所需的所有 TensorFlow 操作,现在我们可以开始用小批量进行优化。如果data_feeder是一个生成器,返回连续的输入和目标批次,那么我们可以通过迭代地提供输入和目标批次...

So, a very good thing to do would be to run some hyperparameter optimization techniques (for example, Grid search / Random search) on the hyperparameters. Below, I listed some of the most critical hyperparameters: The learning rate of the optimizer The number of layers and the number of ...
