Multiscale feature integration network for inpainting of full-sky CMB -modes
Reyhan D. Lambaga, Vipin Sudevan, Pisin Chen
Foreground masking and incomplete sky coverage complicate CMB polarization analyses by inducing mode coupling and imperfect E/B separation, with particularly strong impact on searc…

Introducing a multiscale feature integration network for inpainting with applications to enhanced CMB map reconstruction
Reyhan D. Lambaga, Vipin Sudevan, Pisin Chen
We introduce a novel neural network, SkyReconNet, which combines the expanded receptive fields of dilated convolutional layers along with standard convolutions, to capture both the…

PUREPath-B: A Tessellated Bayesian Model for Recovering CMB B-modes over Large Angular Scales of the Sky
Vipin Sudevan, Pisin Chen
We introduce a comprehensive, custom-developed neural network, the PUREPath-B, that yields a posterior predictive distribution of Cosmic Microwave Background (CMB) B-mode signal co…
