As a consequence, the performance of the system is strongly enhanced. The steps to achieve optimization are analyzed in detail.5 p.application/pdfeng(c) The American Physical Society, 1989Física estadísticaXarxes neuronals (Informàtica)Transformacions de fase (Física estadística)Statistical physicsPhase transformations (Statistical physics)Neural networks (Computer science)Hierarchical neural network with high storage capacityinfo:eu-repo/semantics/article64491info:eu-repo/semantics/openAccess
