Approximate and Weighted Data Reconstruction Attack in Federated Learning
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. Alt…
Computational performance of the MMOC in the inverse design of the Doswell frontogenesis equation
Alexandre Francisco, Umberto Biccari, Enrique Zuazua
Inverse design of transport equations can be addressed by using a gradient-adjoint methodology. In this methodology numerical schemes used for the adjoint resolution determine the…
Null control of heat equations with analytic memory kernels
Qi Lü, Xu Zhang, Enrique Zuazua
We analyze the control properties of heat equations with memory terms. We recall previous results showing that if the moving support of the control covers the whole domain where he…
Boundary observation and control for fractional heat and wave equations
Umberto Biccari, Mahamadi Warma, Enrique Zuazua
We establish boundary observability and control for the fractional heat equation over arbitrary time horizons , within the optimal range of fractional exponents $s \in (1/2,…
