Data-Efficient Classification of Radio Galaxies

1 code implementation • 26 Nov 2020 • Ashwin Samudre, Lijo George, Mahak Bansal, Yogesh Wadadekar

We apply few-shot learning techniques based on Twin Networks and transfer learning techniques using a pre-trained DenseNet model with advanced techniques like cyclical learning rate and discriminative learning to train the model rapidly.

Inferring astrophysical X-ray polarization with deep learning

no code implementations • 16 May 2020 • Nikita Moriakov, Ashwin Samudre, Michela Negro, Fabian Gieseke, Sydney Otten, Luc Hendriks

We investigate the use of deep learning in the context of X-ray polarization detection from astrophysical sources as will be observed by the Imaging X-ray Polarimetry Explorer (IXPE), a future NASA selected space-based mission expected to be operative in 2021.
