About this Research Topic
Recently, reservoir computing has become the focus of research attention. Reservoir computing consists of a recurrent neural network with a reservoir layer and a readout layer. By utilizing nonlinear spatial-temporal patterns against input signals, the parameters of the readout are learned, thus fixing the synaptic weight of the reservoir layer. The size of the learned parameter in this neural network architecture is significantly lower when compared with that of the other neural network architectures. That is, high learning efficiency is achieved. However, the performance of the conventional network architecture of reservoir computing cannot reach that of the above-mentioned network used for the deep learning approach. Although the conventional reservoir computing network architecture consisted of a single reservoir layer, a recent proposal has been made to modify this to a deep-layer architecture consisting of assembly sub-reservoirs (parallel, ring, hub, and multi-layer types). This enhances the performance of reservoir computing, enabling it to reach the performance of deep learning, along with the maintenance of high learning efficiency, which is an advantage of reservoir computing. This development might, thus, open a new avenue for the application of deep neural network architecture in the field of computational intelligence.
