We measured the output voltage of a spin-torque oscillator fed binary input information by a phase-modulated magnetic field and then applied feedback to it. Computing with the output voltages depending on the input information and time requires the conversion of the dynamics to an input-only function (time invariant transformation) by a readout, and we have shown that time invariant transformation can be achieved with the multilayer perceptron, allowing for the short-term memory and parity check.
