Beyond Spectral Gap: The Role of the Topology in Decentralized Learning
Martin Jaggi, Thijs Vogels, Hadrien Hendrikx
In data-parallel optimization of machine learning models, workers collaborate to improve their estimates of the model: more accurate gradients allow them to use larger learning rates and optimize faster. In the decentralized setting, in which workers commu ...
Brookline2023Derivative voltammetry: a simple tool to probe reaction selectivity in photoelectrochemical cells
Kevin Sivula, Florent Alexandre Boudoire, Nukorn Plainpan
We demonstrate the use of the derivative voltammogram method to predict the selectivity of the photo-driven oxidation of 5-hydroxymethylfurfural (HMF) on a WO3 photoanode as a function of applied potential using only information obtained from the linear sw ...
2022A Distributed Luenberger Observer for Linear State Feedback Systems With Quantized and Rate-Limited Communications
Colin Neil Jones, Ye Pu, Andrea Alessandretti, Francisco Fernandes Castro Rego
This article addresses the problem of simultaneous distributed state estimation, and control of linear systems with linear state feedback, subjected to process, and measurement noise, under the constraints of quantized, and rate-limited network data transm ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2021A Modular Multilevel Converter with a Clamping Switch for Quasi-Three-Level Operation
The required module capacitances of modular multilevel converters can be significantly reduced in comparison to conventional operation modes when quasi-two-level operation is applied. Unfortunately, the output voltage distortion becomes similar to those of ...
IEEE2021Stability of time-sensitive networks: strategies for partial regulation
In time-sensitive networks, regulators can be used to reshape traffic, and their usage may be necessary to guarantee stability by providing worst-case delay bounds. In this project, I study partial regulation of time-sensitive networks with cyclic dependen ...
2020Robust optimization of power grid with distributed generation and improved reliability
Amarasinghage Tharindu Dasun Perera, Zhengchao Wang
Uncertainties of demand, generation and component outage can lead to black-outs in the grid. This study proposes an optimization algorithm (based on Benders Decomposition (BD)) to optimize a Power Transmission System (PTS) that is robust to aforementioned ...
ELSEVIER SCIENCE BV2019Medium Voltage Impedance-Admittance Measurement System Based on the Cascaded H-Bridge Multilevel Converter
Drazen Dujic, Francisco Daniel Freijedo Fernández, Marko Petkovic, Nicolai Hildebrandt
Recent trends in power system design such as an increasing share of renewable energy sources and smart grids are creating different subsystem interactions that require proper investigation, understanding, describing and estimating global system stability t ...
2018Development of topological tools for the analysis of biological data
There is a growing need for unbiased clustering algorithms, ideally automated to analyze complex data sets. Topological data analysis (TDA) has been used to approach this problem. This recent field of mathematics discerns characteristic features of a space ...
EPFL2018Topological Structures on DMC spaces
Two channels are said to be equivalent if they are degraded from each other. The space of equivalent channels with input alphabet X and output alphabet Y can be naturally endowed with the quotient of the Euclidean topology by the equivalence relation. We s ...
2017Coevolution of Synchronization and Cooperation in Costly Networked Interactions
Alessio Vincenzo Cardillo, Alberto Antonioni
Despite the large number of studies on synchronization, the hypothesis that interactions bear a cost for involved individuals has seldom been considered. The introduction of costly interactions leads, instead, to the formulation of a dichotomous scenario i ...
