Web昇腾TensorFlow(20.1)-dropout:Description. Description The function works the same as tf.nn.dropout. Scales the input tensor by 1/keep_prob, and the reservation probability of the input tensor is keep_prob. Otherwise, 0 is output, and the shape of the output tensor is the same as that of the input tensor. Now we know why Exploding Gradients occur and how Gradient Clipping can resolve it. We also saw two different methods by virtue of which you can apply Clipping to your deep neural network.
