Abstract
Self-organizing neural networks are used to analyze uncorrelated white noises of different distribution types (normal, triangular, and uniform). The artificially generated noises are analyzed by clustering the measured time signal sequence samples without its preprocessing. Using this approach, we analyze, for the first time, the current noise produced by a sliding “Wigner-crystal”-like structure in the insulating phase of a 2D electron system in silicon. The possibilities of using the method for analyzing and comparing experimental data, obtained by observing various effects in solid-state physics, and numerical data, simulated using theoretical models are discussed.
Key words: self-organizing neural networks, current noise, Wigner crystal, 2D electron systems.
