This is achieved by combining simultaneous observations from pairs of telescopes such that the signal is mathematically equivalent to sampling the Fourier domain of the object. However, reconstructing images from such sparse sampling is a challenging and ill-posed problem, with current methods requiring precise tuning of parameters and manual, iterative cleaning by experts. We present a novel deep learning approach in which the representation in the Fourier domain of an astronomical source is learned implicitly using a neural field representation. Data-driven priors can be added through a transformer encoder. Results on synthetically observed galaxies show that transformer-conditioned neural fields can successfully reconstruct astronomical observations even when the number of visibilities is very sparse.}, number={3}, journal={Proceedings of the AAAI Conference on Artificial Intelligence}, author={Wu, Benjamin and Liu, Chao and Eckart, Benjamin and Kautz, Jan}, year={2022}, month={Jun.}, pages={2685-2693} }
