Reconstructing speech dynamics via a network of stochastic resonance neurons

摘要

As a new framework for understanding sensory mechanism of biological systems that accurately detect input signal, stochastic resonance phenomena have been recently paid a great deal of attention. In particular, Collins et al. reported that network of a large number of stochastic resonance neurons gives rise to robust sensory mechanism for detecting vas ions complex input signals. In this study, we investigate the effectiveness of such stochastic resonance network to chaotic input signals. We also apply the stochastic resonance system for detecting weak speech signals.
