title: Multiple short-term memories in coupled weakly nonlinear map lattices
abstract: We investigate short-time memory storage in coupled map lattices with a periodic external input. In the case of linear coupled maps, the transient length necessary to achieve permanent memory is studied. We present numerical evidence that coupled weakly nonlinear maps are able to store multiple short-time memories, and use this fact to encode symbols in a matrix of pixels, using suitable control laws.
