| Abstract(in English) | Several moving intrinsic localized modes (ILMs) are created via modulational instability of the zone boundary mode in a nonlinear coupled oscillators. In this study, a position detection method using Gaussian mixture model is proposed for individually detecting the moving ILMs. In the proposed method, energy distribution is converted to frequency distribution of the lattice number, and the probability density distribution is estimated by using Gaussian mixture model. Moving ILMs are successfully detected even though their localization is weak. In addition, two moving ILMs are individually detected when they collided. |
