Denoising medium resolution stellar spectra with U-Net convolutional neural networks
Balázs Pál, László Dobos
We investigated the use of a U-Net convolutional neural network for denoising simulated medium-resolution spectroscopic observations of stars. Simulated spectra were generated unde…

Denoising medium resolution stellar spectra with neural networks
Balázs Pál, László Dobos
We trained denoiser autoencoding neural networks on medium resolution simulated optical spectra of late-type stars to demonstrate that the reconstruction of the original flux is po…
