Accelerator-driven Data Arrangement to Minimize Transformers Run-time on Multi-core Architectures
David Atienza Alonso, Giovanni Ansaloni, Alireza Amirshahi
The increasing complexity of transformer models in artificial intelligence expands their computational costs, memory usage, and energy consumption. Hardware acceleration tackles the ensuing challenges by designing processors and accelerators tailored for t ...
2024Computational Imaging SPAD Cameras
Vision systems built around conventional image sensors have to read, encode and transmit large quantities of pixel information, a majority of which is redundant. As a result, new computational imaging sensor architectures were developed to preprocess the r ...
EPFL2023Fabrication and Characterization of High Aspect Ratio Amorphous Silicon Based Microchannel Plates
Christophe Ballif, Janina Christine Isabelle Löffler, Samira Alexandra Frey, Mohammad Beygi
This contribution focuses on the fabrication and characterization of microchannel plates made of hydrogenated amorphous silicon (AMCPs). Flexible fabrication processes and the semi-conducting nature of amorphous silicon could give these detectors the advan ...
2021Collaborative Learning in the Jungle (Decentralized, Byzantine, Heterogeneous, Asynchronous and Nonconvex Learning)
Rachid Guerraoui, Sadegh Farhadkhani, El Mahdi El Mhamdi, Le Nguyen Hoang, Sébastien Louis Alexandre Rouault, Arsany Hany Abdelmessih Guirguis
We study Byzantine collaborative learning, where n nodes seek to collectively learn from each others' local data. The data distribution may vary from one node to another. No node is trusted, and f < n nodes can behave arbitrarily. We prove that collaborati ...
2021A Structure Theorem for Level Sets of Multiplicative Functions and Applications
Given a level set E of an arbitrary multiplicative function f, we establish, by building on the fundamental work of Frantzikinakis and Host [14, 15], a structure theorem that gives a decomposition of into an almost periodic and a pseudo-random part ...
2020Efficacy of a Computer-Based Learning Program in Children With Developmental Dyscalculia. What Influences Individual Responsiveness?
This study presents the evaluation of a computer-based learning program for children with developmental dyscalculia and focuses on factors affecting individual responsiveness. The adaptive training program Calcularis 2.0 has been developed according to cur ...
2020Characterization of Amorphous Silicon Based Microchannel Plates with High Aspect Ratio
Christophe Ballif, Janina Christine Isabelle Löffler
Microchannel plates (MCPs) fabricated out of hydrogenated amorphous silicon offer a promising alternative to conventional lead glass ones. Progress in the fabrication process has allowed for detectors with higher aspect ratios, which significantly increase ...
IEEE2019Reducing the Multiplicative Complexity in Logic Networks for Cryptography and Security Applications
Giovanni De Micheli, Mathias Soeken, Luca Gaetano Amarù, Eleonora Testa
Reducing the number of AND gates plays a central role in many cryptography and security applications. We propose a logic synthesis algorithm and tool to minimize the number of AND gates in a logic network composed of AND, XOR, and inverter gates. Our appro ...
ASSOC COMPUTING MACHINERY2019The Role of Multiplicative Complexity in Compiling Low T-count Oracle Circuits
Giovanni De Micheli, Mathias Soeken, Giulia Meuli
We present a constructive method to create quantum circuits that implement oracles vertical bar x vertical bar y |0 (k) -> vertical bar x vertical bar y circle plus f(x)vertical bar 0 (k) for n-variable Boolean functions f with low T-count. In our method f ...
IEEE2019Sur quelques équations aux dérivées partielles en lien avec le lemme de Poincaré
In this thesis, we study two distinct problems.
The first problem consists of studying the linear system of partial differential equations which consists of taking a k-form, and applying the exterior derivative 'd' to it and add the wedge product with a 1- ...
