Tailoring the dynamics of spintronic neural networks

Publications /

Nonlinear random projection machines are efficient neural networks capable of classifying real- life data with lower computational demands compared to standard artificial neural networks. They are well-suited for hardware implementation using nonlinear devices, enabling the creation of low-power hardware neural networks. We implement such a network using vortex-based spin-torque oscillators (STVOs), magnetic tunnel junctions (MTJs) that transform input signals nonlinearly at low power. We identify three physical parameters affecting the STVO dynamics and the network’s performance during data classification. We demonstrate their impact on a simplified nonlinear separation task and optimize them using ultrafast data-driven simulations for image recognition on the MNIST dataset. This approach holds potential for further hyperparameter optimization in STVO-based hardware random projection machines, and for the efficient development of custom neural architectures tailored for neuromorphic data classification Authors: Moureaux, Anatole ; de Wergifosse, Simon; Chopin, Chloe, Abreu Araujo, Flavio.

Deliverable 1.1: Data Management Plan

Publications /

This Data Management Plan (DMP) for the MultiSpin.AI project provides a framework for how data material will be handled during and after the end of the project. This document provides an overview of the datasets that will be collected, used and re-used within Multispin.AI. It is not a fixed document; it is a living document that will evolve during the lifespan of the project to include the research data that will be generated. It will therefore be supplemented during the interim and final reports.
