Abstract

Fabricating powerful neuromorphic chips the size of a thumb requires miniaturizing both hardware synapses and neurons. The challenge for neurons is to scale them down to submicrometer diameters while maintaining the properties that allow for reliable information processing: high signal to noise ratio, endurance, stability, reproducibility. The best way to test if an artificial neuron possesses these characteristics is to quantify its ability to realize an actual cognitive task. Here we analyze the performance of spin-torque nano-oscillators for Reservoir Computing.
