The purpose of neuromorphic computing is to take inspiration from the brain to build hardware neural networks that can learn to perform useful tasks with low energy consumption [1]. In this talk, I will show that spintronic nano-oscillators based on magnetic tunnel junctions can act as artificial neurons [2]. I will present our first results of pattern recognition with small networks of coupled oscillators [3]. I will then show that these microwave nano-neurons open the path to wireless deep learning.
