Fast Weight Long Short-Term Memory
Associative memory using fast weights is a short-term memory mechanism that
substantially improves the memory capacity and time scale of recurrent neural
networks (RNNs). As recent studies introduced fast weights only to regular
RNNs, it is unknown whether fast weight memory is beneficial to gated RNNs. In
this work, we report a significant synergy between long short-term memory
(LSTM) networks and fast weight associative memories. We show that this
combination, in learning associative retrieval tasks, results in much faster
training and lower test error, a performance boost most prominent at high
memory task difficulties
