Chapter 5: Memory-Augmented Neural Networks

1. NTM is an interesting algorithm that has the ability to store and retrieve information from memory. The idea of NTM is to augment the neural network with external memory—that is, instead of using hidden states as memory, it uses external memory to store and retrieve information. 
2. The controller is basically a feed-forward neural network or recurrent neural network. It reads from and writes to memory.
3. The read head and write head are the pointers containing addresses of the memory that it has to read from and write to.
4. The memory matrix or memory bank, or simply the memory, is where we will store the information. Memory is basically a two-dimensional matrix composed of memory cells. The memory matrix ...
