Initialisation and Topology Effects in Decentralised Federated Learning

1 code implementation23 Mar 2024 Arash Badie-Modiri, Chiara Boldrini, Lorenzo Valerio, János Kertész, Márton Karsai

Fully decentralised federated learning enables collaborative training of individual machine learning models on distributed devices on a network while keeping the training data localised.

Federated Learning

Impact of network topology on the performance of Decentralized Federated Learning

no code implementations28 Feb 2024 Luigi Palmieri, Chiara Boldrini, Lorenzo Valerio, Andrea Passarella, Marco Conti

We highlight the challenges in transferring knowledge from peripheral to central nodes, attributed to a dilution effect during model aggregation.

Clustering Federated Learning

Coordination-free Decentralised Federated Learning on Complex Networks: Overcoming Heterogeneity

no code implementations7 Dec 2023 Lorenzo Valerio, Chiara Boldrini, Andrea Passarella, János Kertész, Márton Karsai, Gerardo Iñiguez

Federated Learning (FL) is a well-known framework for successfully performing a learning task in an edge computing scenario where the devices involved have limited resources and incomplete data representation.

Edge-computing Federated Learning

The effect of network topologies on fully decentralized learning: a preliminary investigation

no code implementations29 Jul 2023 Luigi Palmieri, Lorenzo Valerio, Chiara Boldrini, Andrea Passarella

Specifically, we highlight the different roles in this process of more or less connected nodes (hubs and leaves), as well as that of macroscopic network properties (primarily, degree distribution and modularity).

Structural invariants and semantic fingerprints in the "ego network" of words

no code implementations1 Mar 2022 Kilian Ollivier, Chiara Boldrini, Andrea Passarella, Marco Conti

In this respect, ring #1 can be seen as the semantic fingerprint of the ego network of words.

Weak Signals in the Mobility Landscape: Car Sharing in Ten European Cities

no code implementations20 Sep 2021 Chiara Boldrini, Raffaele Bruno, Haitam Laarabi

Car sharing is one the pillars of a smart transportation infrastructure, as it is expected to reduce traffic congestion, parking demands and pollution in our cities.

Harnessing the Power of Ego Network Layers for Link Prediction in Online Social Networks

no code implementations19 Sep 2021 Mustafa Toprak, Chiara Boldrini, Andrea Passarella, Marco Conti

In order to validate this claim, we focus on popular feature-extraction prediction algorithms (both unsupervised and supervised) and we extend them to include social-circles awareness.

Link Prediction

Car sharing through the data analysis lens

no code implementations25 Jul 2017 Chiara Boldrini, Raffaele Bruno, Haitam Laarabi

Car sharing is one the pillars of a smart transportation infrastructure, as it is expected to reduce traffic congestion, parking demands and pollution in our cities.
