Machine learning has a long history in astronomy, but since around 2016 deep learning (DL) only got traction. Here I summarise effords and publications of DL in the astrophysical community.
The main field of ML applications in astrophysics is object classification. With source counts now ranging into the 107-108 for most surveys, machine learning is put to use to allow the classification of a large number of sources which would otherwise need an infeasible amount of manpower:
- CATALOGING ACCRETED STARS WITHIN GAIA DR2 USING DEEP LEARNING 07/2019 - Three hidden-layer FCN with 4-9 initial input features, trained on simulations for 2-class classification.
- Classifying galaxies according to their HI content 06/2019 - SVM perform best in specisifity and is hence used over a DNN
