The back propagation algorithm (BP algorithm) mainly has two stages: forward propagation stage and back propagation stage, which completes the parameter update work in the neural network.

The hidden layer is the intermediate layer between the input and output layers in the neural network. The training data does not give the output results required by these hidden layers.

The waveform sequence of an audio file is the information of the signal in the time domain.

Which of the following options does not belong to the gate of the LSTM cell?

During ModelArts training, you can dynamically monitor the training process, including service resource consumption, configuration information, logs, resource usage, Tensorboard visualization, version comparison, etc.
