Physical reservoir computing -- An introductory perspective
Kohei Nakajima
Understanding the fundamental relationships between physics and its information-processing capability has been an active research topic for many years. Physical reservoir computing…
Optimal short-term memory before the edge of chaos in driven random recurrent networks
Taichi Haruna, Kohei Nakajima
The ability of discrete-time nonlinear recurrent neural networks to store time-varying small input signals is investigated by mean-field theory. The combination of a small input st…
Symbolic local information transfer
Kohei Nakajima, Taichi Haruna
Recently, the permutation-information theoretic approach has been used in a broad range of research fields. In particular, in the study of highdimensional dynamical systems, it has…
Dynamics Underneath Symbols: A Case Study in Autonomous Agents
Kohei Nakajima
Our cognition is structuring the informational layer, consisting of perception, anticipation, and action, and it should also be sustained on a physical basis. In this paper, we aim…
