FedADMM-InSa: An Inexact and Self-Adaptive ADMM for Federated Learning

no code implementations21 Feb 2024 Yongcun Song, Ziqi Wang, Enrique Zuazua

First, we design an inexactness criterion for the clients' local updates to eliminate the need for empirically setting the local training accuracy.

Interplay between depth and width for interpolation in neural ODEs

no code implementations18 Jan 2024 Antonio Álvarez-López, Arselane Hadj Slimane, Enrique Zuazua

Our findings reveal a balancing trade-off between $p$ and $L$, with $L$ scaling as $O(1+N/p)$ for dataset interpolation, and $L=O\left(1+(p\varepsilon^d)^{-1}\right)$ for measure interpolation.

Optimized classification with neural ODEs via separability

no code implementations21 Dec 2023 Antonio Álvarez-López, Rafael Orive-Illera, Enrique Zuazua

Classification of $N$ points becomes a simultaneous control problem when viewed through the lens of neural ordinary differential equations (neural ODEs), which represent the time-continuous limit of residual networks.

Approximate and Weighted Data Reconstruction Attack in Federated Learning

no code implementations13 Aug 2023 Yongcun Song, Ziqi Wang, Enrique Zuazua

Federated Learning (FL) is a distributed learning paradigm that enables multiple clients to collaborate on building a machine learning model without sharing their private data.

Turnpike in optimal control of PDEs, ResNets, and beyond

no code implementations8 Feb 2022 Borjan Geshkovski, Enrique Zuazua

The \emph{turnpike property} in contemporary macroeconomics asserts that if an economic planner seeks to move an economy from one level of capital to another, then the most efficient path, as long as the planner has enough time, is to rapidly move stock to a level close to the optimal stationary or constant path, then allow for capital to develop along that path until the desired term is nearly reached, at which point the stock ought to be moved to the final target.

Sidewise control of 1-d waves

no code implementations2 Jan 2021 Yesim Sarac, Enrique Zuazua

We analyze the sidewise controllability for the variable coefficients one-dimensional wave equation.

Large-time asymptotics in deep learning

1 code implementation6 Aug 2020 Carlos Esteve, Borjan Geshkovski, Dario Pighin, Enrique Zuazua

We consider the neural ODE perspective of supervised learning and study the impact of the final time $T$ (which may indicate the depth of a corresponding ResNet) in training.
