Vowel recognition with four coupled spin-torque nano-oscillators
M. Romera,Philippe Talatchian,Sumito Tsunegi,Flavio Abreu Araujo,Flavio Abreu Araujo,Vincent Cros,Paolo Bortolotti,Juan Trastoy,Kay Yakushiji,Akio Fukushima,Hitoshi Kubota,Shinji Yuasa,Maxence Ernoult,Damir Vodenicarevic,Tifenn Hirtzlin,Nicolas Locatelli,Damien Querlioz,Julie Grollier +17 more
TL;DR: In this paper, the authors demonstrate that non-trivial pattern classification tasks can be achieved with small hardware neural networks by endowing them with nonlinear dynamical features such as oscillations and synchronization.

TL;DR: The results demonstrate that non-trivial pattern classification tasks can be achieved with small hardware neural networks by endowing them with nonlinear dynamical features such as oscillations and synchronization, and that the high experimental recognition rates stem from the ability of these oscillators to synchronize.

Neuromorphic computing with nanoscale spintronic oscillators
Jacob Torrejon,Mathieu Riou,Flavio Abreu Araujo,Sumito Tsunegi,Guru Khalsa,Damien Querlioz,Paolo Bortolotti,Vincent Cros,Akio Fukushima,Hitoshi Kubota,Shinji Yuasa,Mark D. Stiles,Julie Grollier +12 more
TL;DR: It is shown experimentally that a nanoscale spintronic oscillator can be used to achieve spoken-digit recognition with an accuracy similar to that of state-of-the-art neural networks and the regime of magnetization dynamics that leads to the greatest performance is determined.
Journal ArticleDOI
Skyrmion Gas Manipulation for Probabilistic Computing
Daniele Pinna,Flavio Abreu Araujo,Joo-Von Kim,Vincent Cros,Damien Querlioz,Perre Bessiere,Jacques Droulez,Julie Grollier +7 more
TL;DR: In this paper, the topologically protected magnetic spin configurations known as skyrmions offer promising applications due to their stability, mobility and localization, and the authors emphasize how to leverage the thermally driven dynamics of an ensemble of such particles to perform computing tasks.
Journal ArticleDOI
Efficient Synchronization of Dipolarly Coupled Vortex-Based Spin Transfer Nano-Oscillators.
Nicolas Locatelli,Abbass Hamadeh,Flavio Abreu Araujo,A. D. Belanovsky,P. N. Skirdkov,Romain Lebrun,V. V. Naletov,V. V. Naletov,K. A. Zvezdin,Manuel Muñoz,Julie Grollier,Olivier Klein,Olivier Klein,Vincent Cros,Grégoire de Loubens +14 more
TL;DR: In this paper, a pair of vortex-based spin transfer nano-oscillators were experimentally studied, in which mutual synchronization can be achieved despite a significant frequency mismatch between oscillators.
