Synaptic metaplasticity with multi-level memristive devices

no code implementations21 Jun 2023 Simone D'Agostino, Filippo Moro, Tifenn Hirtzlin, Julien Arcamone, Niccolò Castellani, Damien Querlioz, Melika Payvand, Elisa Vianello

In this work, we extend this solution to quantized neural networks (QNNs) and present a memristor-based hardware solution for implementing metaplasticity during both inference and training.

Model of the Weak Reset Process in HfOx Resistive Memory for Deep Learning Frameworks

no code implementations2 Jul 2021 Atreya Majumdar, Marc Bocquet, Tifenn Hirtzlin, Axel Laborieux, Jacques-Olivier Klein, Etienne Nowak, Elisa Vianello, Jean-Michel Portal, Damien Querlioz

However, the resistive change behavior in this regime suffers many fluctuations and is particularly challenging to model, especially in a way compatible with tools used for simulating deep learning.

Synaptic metaplasticity in binarized neural networks

2 code implementations19 Jan 2021 Axel Laborieux, Maxence Ernoult, Tifenn Hirtzlin, Damien Querlioz

Unlike the brain, artificial neural networks, including state-of-the-art deep neural networks for computer vision, are subject to "catastrophic forgetting": they rapidly forget the previous task when trained on a new one.

In-Memory Resistive RAM Implementation of Binarized Neural Networks for Medical Applications

no code implementations20 Jun 2020 Bogdan Penkovsky, Marc Bocquet, Tifenn Hirtzlin, Jacques-Olivier Klein, Etienne Nowak, Elisa Vianello, Jean-Michel Portal, Damien Querlioz

With new memory technology available, emerging Binarized Neural Networks (BNNs) are promising to reduce the energy impact of the forthcoming machine learning hardware generation, enabling machine learning on the edge devices and avoiding data transfer over the network.

Synaptic Metaplasticity in Binarized Neural Networks

1 code implementation7 Mar 2020 Axel Laborieux, Maxence Ernoult, Tifenn Hirtzlin, Damien Querlioz

In this work, we interpret the hidden weights used by binarized neural networks, a low-precision version of deep neural networks, as metaplastic variables, and modify their training technique to alleviate forgetting.

Implementing Binarized Neural Networks with Magnetoresistive RAM without Error Correction

no code implementations12 Aug 2019 Tifenn Hirtzlin, Bogdan Penkovsky, Jacques-Olivier Klein, Nicolas Locatelli, Adrien F. Vincent, Marc Bocquet, Jean-Michel Portal, Damien Querlioz

One of the most exciting applications of Spin Torque Magnetoresistive Random Access Memory (ST-MRAM) is the in-memory implementation of deep neural networks, which could allow improving the energy efficiency of Artificial Intelligence by orders of magnitude with regards to its implementation on computers and graphics cards.

Stochastic Computing for Hardware Implementation of Binarized Neural Networks

1 code implementation3 Jun 2019 Tifenn Hirtzlin, Bogdan Penkovsky, Marc Bocquet, Jacques-Olivier Klein, Jean-Michel Portal, Damien Querlioz

In this work, we propose a stochastic computing version of Binarized Neural Networks, where the input is also binarized.
