Input parameter ranking for neural networks in a space weather regression problem
Lotz, Stefan; Beukes, Jacques P.; Davel, Marelie H. (In Proc. South African Forum for Artificial Intelligence Research (FAIR2019), 2019-12)Geomagnetic storms are multi-day events characterised by significant perturbations to the magnetic field of the Earth, driven by so-lar activity. Numerous efforts have been undertaken to utilise in-situ mea-surements of ... -
A neural network based method for input parameter selection
Lotz, Stefan; Beukes, Jacques P.; Davel, Marelie H. (Machine Learning in Heliophysics, 2019-09)NNs yield predictions, without aiding understanding of input-output relationship Fully connected networks mix signal from all inputs as information flows through the network Input parameter selection usually done
