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.

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.

Interpreting wealth distribution via poverty map inference using multimodal data

1 code implementation17 Feb 2023 Lisette Espín-Noboa, János Kertész, Márton Karsai

Here, we propose a pipeline of machine learning models to infer the mean and standard deviation of wealth across multiple geographically clustered populated places, and illustrate their performance in Sierra Leone and Uganda.

Socioeconomic correlations of urban patterns inferred from aerial images: interpreting activation maps of Convolutional Neural Networks

1 code implementation10 Apr 2020 Jacob Levy Abitbol, Márton Karsai

Urbanisation is a great challenge for modern societies, promising better access to economic opportunities while widening socioeconomic inequalities.

weg2vec: Event embedding for temporal networks

no code implementations6 Nov 2019 Maddalena Torricelli, Márton Karsai, Laetitia Gauvin

Network embedding techniques are powerful to capture structural regularities in networks and to identify similarities between their local fabrics.

Network Embedding

Joint embedding of structure and features via graph convolutional networks

1 code implementation21 May 2019 Sébastien Lerique, Jacob Levy Abitbol, Márton Karsai

The creation of social ties is largely determined by the entangled effects of people's similarities in terms of individual characters and friends.

Location, Occupation, and Semantics based Socioeconomic Status Inference on Twitter

no code implementations16 Jan 2019 Jacobo Levy Abitbol, Márton Karsai, Eric Fleury

The socioeconomic status of people depends on a combination of individual characteristics and environmental variables, thus its inference from online behavioral data is a difficult task.

Socioeconomic Dependencies of Linguistic Patterns in Twitter: A Multivariate Analysis

no code implementations3 Apr 2018 Jacob Levy Abitbol, Márton Karsai, Jean-Philippe Magué, Jean-Pierre Chevrot, Eric Fleury

Our usage of language is not solely reliant on cognition but is arguably determined by myriad external factors leading to a global variability of linguistic patterns.

Prepaid or Postpaid? That is the question. Novel Methods of Subscription Type Prediction in Mobile Phone Services

no code implementations30 Jun 2017 Yongjun Liao, Wei Du, Márton Karsai, Carlos Sarraute, Martin Minnoni, Eric Fleury

Our study reveals that (a) postpaid customers are more active in terms of service usage and (b) there are strong structural correlations in the mobile phone call network as connections between customers of the same subscription type are much more frequent than those between customers of different subscription types.
