How does LSTM in deep reinforcement learning differ from experience replay?

In the paper Deep Recurrent Q-Learning for Partially Observable MDPs, the author processed the Atari game frames with an LSTM layer at the end. My questions are: How does this method differ from the ...

What can be considered a deep recurrent neural network?

In the paper Deep Recurrent Q-Learning for Partially Observable MDPs, the DRQN is described as DQN with the first post-convolutional fully-connected layer replaced by a recurrent LSTM. I have DQN ...

Number of nodes in hidden layer for LSTM

I am starting to learn LSTM by understanding how it is used for creating a char-RNN and had a fundamental question. Does the number of nodes in the hidden layer need to be the same as that of the ...
