Astronomical Images Quality Assessment with Automated Machine Learning

no code implementations17 Nov 2023 Olivier Parisot, Pierrick Bruneau, Patrik Hitzelberger

Electronically Assisted Astronomy consists in capturing deep sky images with a digital camera coupled to a telescope to display views of celestial objects that would have been invisible through direct observation.

Forecasting Intraday Power Output by a Set of PV Systems using Recurrent Neural Networks and Physical Covariates

no code implementations15 Mar 2023 Pierrick Bruneau, David Fiorelli, Christian Braun, Daniel Koster

We build upon a physical, deterministic PV performance model, the output of which being used as covariates in the context of the neural model.

Cold Start Active Learning Strategies in the Context of Imbalanced Classification

no code implementations25 Jan 2022 Etienne Brangbour, Pierrick Bruneau, Thomas Tamisier, Stéphane Marchand-Maillet

We present novel active learning strategies dedicated to providing a solution to the cold start stage, i. e. initializing the classification of a large set of data with no attached labels.

Computing flood probabilities using Twitter: application to the Houston urban area during Harvey

no code implementations7 Dec 2020 Etienne Brangbour, Pierrick Bruneau, Stéphane Marchand-Maillet, Renaud Hostache, Marco Chini, Patrick Matgen, Thomas Tamisier

In this paper, we investigate the conversion of a Twitter corpus into geo-referenced raster cells holding the probability of the associated geographical areas of being flooded.

Benchmarking multimedia technologies with the CAMOMILE platform: the case of Multimodal Person Discovery at MediaEval 2015

no code implementations LREC 2016 Johann Poignant, Herv{\'e} Bredin, Claude Barras, Mickael Stefas, Pierrick Bruneau, Thomas Tamisier

In this paper, we claim that the CAMOMILE collaborative annotation platform (developed in the framework of the eponymous CHIST-ERA project) eases the organization of multimedia technology benchmarks, automating most of the campaign technical workflow and enabling collaborative (hence faster and cheaper) annotation of the evaluation data.
