no code implementations • 25 Feb 2021 • Zhen Lin, Nicholas Huang, Camille Avestruz, W. L. Kimmy Wu, Shubhendu Trivedi, João Caldeira, Brian Nord

We present a comparison between two methods of cluster identification: the standard Matched Filter (MF) method in SZ cluster finding and a method using Convolutional Neural Networks (CNN).

Sounds Discordant: Classical Distance Ladder & $Λ$CDM -based Determinations of the Cosmological Sound Horizon

DeepCMB: Lensing Reconstruction of the Cosmic Microwave Background with Deep Neural Networks

1 code implementation • 2 Oct 2018 • João Caldeira, W. L. Kimmy Wu, Brian Nord, Camille Avestruz, Shubhendu Trivedi, Kyle T. Story

In this work, we demonstrate reconstruction of the CMB lensing potential with deep convolutional neural networks (CNN) - ie, a ResUNet.
