Discrete time recurrent neural network architectures: A unifying review. (English) Zbl 0879.68092
Summary: After giving definitions for a set of commonly used terms in recurrent neural networks (RNNs), all possible RNN architectures based on these definitions are enumerated, and described. Then, most existing RNN architectures are categorized under these headings. Four general neural network architectures, in increasing degree of complexity, are introduced. It is shown that all the existing RNN architectures can be considered as special cases of the general RNN architectures. Furthermore, it is shown how these existing architectures can be transformed to the general RNN architectures. Some open issues concerning RNN architectures are discussed.
