Abstract (in Japanese) (See Japanese page) 
(in English) Reservoir computing (RC) is known to be a novel information processing framework, which exploits the inherent transient dynamics of recurrent neural networks (RNNs) as a computational resource. RC possesses high information processing capability but, in some cases, the empirical optimization using the control parameters is required. In this study, we propose recurrent infomax (RI) as a alternative method to the empirical optimization. RI is an unsupervised learning scheme that maximizes the mutual information of RNNs by adjusting the connection strengths of the network. Concequently, a delay-line structure can be observed on the network optimized by RI and the network possesses superior short-term memory, which is the ability to encode the information of the input stream in its transient dynamics.
