Cycle-StarNet: Bridging the gap between theory and data by leveraging large datasets

1 code implementation6 Jul 2020 Teaghan O'Briain, Yuan-Sen Ting, Sébastien Fabbro, Kwang M. Yi, Kim Venn, Spencer Bialek

To accomplish this, synthetic models are morphed into spectra that resemble observations, thereby reducing the gap between theory and observations.

Interpreting Stellar Spectra with Unsupervised Domain Adaptation

no code implementations6 Jul 2020 Teaghan O'Briain, Yuan-Sen Ting, Sébastien Fabbro, Kwang M. Yi, Kim Venn, Spencer Bialek

We discuss how to achieve mapping from large sets of imperfect simulations and observational data with unsupervised domain adaptation.
