★ Mar 2022 – New paper accepted at IEEE WoWMoM 2022. We show how a hybrid approach combining statistical modelling and machine learning through a joint AutoML training process can outperform pure deep learning architectures in forecasting tasks. We evaluate the proposed solution in practical anticipatory networking use cases, demonstrating the generality of the solution. Preprint to appear soon.
★ Jan 2022 – New paper accepted at IEEE Percom 2022. This is another installment in our series of works on generating synthetic mobile network traffic, in collaboration with the usual team at University of Edinburgh, Orange and Samsung. This study focuses on the spatial dimension of the aggregate demands. Preprint and open datasets to come soon.
★ Jan 2022 – One paper accepted at The ACM Web Conference 2022. Congratulations to Sachit for his first paper as first author. The work uses extensive measurement data to investigate the interaction between consumption of mobile services and urbanization levels. It unveils a growing imbalance in the per-capita consumption of overall and per-app mobile data traffic during the past years between smaller and larger cities in France, and raises interesting questions on the presence of second-level digital divides in developed countries. The preprint will be out soon.
★ Dec 2021 – Two papers accepted at IEEE INFOCOM 2022. Congratulations to Alan, André, Orlando and Sachit for the first publications of their PhD. The first work explores loss function meta-learning models aimed at supporting Intent-Based Networking, see the postprint. The second study analyzes the impact of measures enacted to limit the COVID-19 pandemic on mobile service usage at a national scale, in collaboration with Orange Innovation, see the postprint.
★ Dec 2021 – New paper presented at ACM CoNEXT. In order to remove the current access barrier to spatiotemporal mobile traffic data for research purposes, we propose SpectraGAN, a deep learning model capable of generating realistic mobile traffic demands for target urban areas from publicly available local information such as demographics or land use. SpectraGAN is the result of a joint effort with the University of Edinburgh, Orange and Samsung. A video presentation of the tool as well as several open datasets generated with SpectraGAN are available.
★ Nov 2021 – We have openings for two new PhD students in the group. The positions are in the area of experimental Artificial Intelligence for the support of next-generation mobile network functionalities, are offered within the context of collaborations with industry and international research projects, and are fully funded. Find more information on the positions and application instructions in the Jobs section below.
★ Nov 2021 – New paper accepted at Journal of the Royal Society Interface. We investigate geographical unevenness in mobile service usage across areas characterized by different income or education levels, and find a gap so evident that aggregated traffic alone allows to accurately infer the socioeconomic status of a small area. Joint work with Universidad Carlos III de Madrid, Orange Labs, and MIT. The work received news coverage from El País, a major newspaper in Spain.
