no code implementations2 Jan 2024 Michele Piana, Federico Benvenuto, Anna Maria Massone, Cristina Campi, Sabrina Guastavino, Francesco Marchetti, Paolo Massa, Emma Perracchione, Anna Volpara

AI-FLARES (Artificial Intelligence for the Analysis of Solar Flares Data) is a research project funded by the Agenzia Spaziale Italiana and by the Istituto Nazionale di Astrofisica within the framework of the ``Attivit\`a di Studio per la Comunit\`a Scientifica Nazionale Sole, Sistema Solare ed Esopianeti'' program.

3D Pose Nowcasting: Forecast the Future to Improve the Present

no code implementations24 Aug 2023 Alessandro Simoni, Francesco Marchetti, Guido Borghi, Federico Becattini, Lorenzo Seidenari, Roberto Vezzani, Alberto del Bimbo

Technologies to enable safe and effective collaboration and coexistence between humans and robots have gained significant importance in the last few years.

Pose Estimation

A comprehensive theoretical framework for the optimization of neural networks classification performance with respect to weighted metrics

no code implementations22 May 2023 Francesco Marchetti, Sabrina Guastavino, Cristina Campi, Federico Benvenuto, Michele Piana

In many contexts, customized and weighted classification scores are designed in order to evaluate the goodness of the predictions carried out by neural networks.

Interpolation with the polynomial kernels

no code implementations15 Dec 2022 Giacomo Elefante, Wolfgang Erb, Francesco Marchetti, Emma Perracchione, Davide Poggiali, Gabriele Santin

We will then study the Reproducing Kernel Hilbert Spaces (or native spaces) of these kernels and their norms, and provide inclusion relations between spaces corresponding to different kernel parameters.

Operational solar flare forecasting via video-based deep learning

no code implementations12 Sep 2022 Sabrina Guastavino, Francesco Marchetti, Federico Benvenuto, Cristina Campi, Michele Piana

Operational flare forecasting aims at providing predictions that can be used to make decisions, typically at a daily scale, about the space weather impacts of flare occurrence.
