Assembly | Vienna: EGU23 – European Geosciences Union

Where and when

Vienna, Austria – April 23rd-28th, 2023

The EGU23 Assembly brings together geoscientists from around the world, especially early-career researchers, in a forum that provides an opportunity to present their work and discuss their ideas with experts in all fields of space weather and geoscience in general.

    Title: The path from scientific to operational flare forecasting: a deep learning approach  
    Autors: Sabrina Guastavino, Francesco Marchetti, Federico Benvenuto, Cristina Campi, Anna Maria Massone, and Michele Piana  
    Abstract: In our view, machine/deep learning for flare forecasting is still more a promise for future scenarios than the reference framework for current operational facilities. This delay from the application of AI methods in research settings to their use for real-time forecasting is probably due to the persistence of technical open issues involving, by instance, the optimization strategy of the training phase, the quantitative assessment of the prediction performances, the reduction of the computational burden. This talk proposes a video-based deep learning approach to flare forecasting in which the optimization of the network’s parameters is realized by means of a probabilistic score-oriented loss function, the training procedure accounts for the part of the solar cycle progression when the prediction is requested, and the prediction performances are assessed by means of value-weighted skill scores that give greater importance to the values of the prediction than to its quality. The talk will also show the operational potentialities of this approach and discuss how feature selection may reduce the information redundancy, thus increasing the computational efficiency.
