Information Processing Capacity of Spintronic Oscillator

Physical reservoir computing is a framework that enables energy-efficient information processing by using physical systems. Nonlinear dynamics in systems provide computational capability unique to reservoirs. It is, however, difficult find an appropriate task for because of the complexity nonlinear processing. The capacity has recently been used clarify systematically tasks are solved reservoirs; it quantifies memory reservoirs accordance with order nonlinearity. Herein, experimental evaluation spintronic oscillator consisting nanostructured ferromagnets reported. state electrically manipulated adding delayed-feedback circuit. total reaches maximum 5.6 at edge echo property. A trade-off between linear and components also found. result can be better understand good matches tasks. As example, function-approximation performed found efficiently when appropriately tuned so its task.
