Abstract: The long short-term memory (LSTM) network trained by gradient descent solves difficult problems which traditional recurrent neural networks in general cannot. We have recently observed that the decoupled extended Kalman filter training algorithm allows for even better performance, reducing significantly the number of training steps when compared to the original gradient descent training algorithm. In this paper we present a set of experiments which are unsolvable by classical recurrent networks but which are solved elegantly and robustly and quickly by LSTM combined with Kalman filters.

Learning context sensitive languages with LSTM trained with Kalman filters 2002 Proceedings of the International Conference on Artificial Neural Networks, ICANN 2002 , Vol. 2415 , pp. 655-660   URL 
Abstract: Unlike traditional recurrent neural networks, the Long ShortTerm Memory (LSTM) model generalizes well when presented with training sequences derived from regular and also simple nonregular languages. Our novel combination of LSTM and the decoupled extended Kalman filter, however, learns even faster and generalizes even better, requiring only the 10 shortest exemplars ($n leq 10$) of the context sensitive language $a^nb^nc^n$ to deal correctly with values of $n$ up to 1000 and more. Even when we consider the relatively high update complexity per timestep, in many cases the hybrid offers faster learning than LSTM by itself.
