Predicting coronal mass ejection travel times using enhanced model-guided machine learning

M. Lampani, M. Rossi, S. Guastavino +2

Coronal mass ejections (CMEs) are key drivers of space weather events, posing risks to both space-borne and ground-based systems. Accurate prediction of their arrival time at Earth…

Weak convergence rates for spectral regularization via sampling inequalities

Sabrina Guastavino, Gabriele Santin, Francesco Marchetti +1

Convergence rates in spectral regularization methods quantify the approximation error in inverse problems as a function of the noise level or the number of sampling points. Classic…

The Multiclass Score-Oriented Loss (MultiSOL) on the Simplex

Francesco Marchetti, Edoardo Legnaro, Sabrina Guastavino

In the supervised binary classification setting, score-oriented losses have been introduced with the aim of optimizing a chosen performance metric directly during the training phas…

Multiclass threshold-based classification and model evaluation

Edoardo Legnaro, Sabrina Guastavino, Francesco Marchetti

In this paper, we introduce a threshold-based framework for multiclass classification that generalizes the standard argmax rule. This is done by replacing the probabilistic interpr…

Feature Understanding and Sparsity Enhancement via 2-Layered kernel machines (2L-FUSE)

Fabiana Camattari, Sabrina Guastavino, Francesco Marchetti +1

We propose a novel sparsity enhancement strategy for regression tasks, based on learning a data-adaptive kernel metric, i.e., a shape matrix, through 2-Layered kernel machines. The…
