Deep Learning for Line Intensity Mapping Observations: Information Extraction from Noisy Maps

no code implementations2 Oct 2020 Kana Moriwaki, Masato Shirasaki, Naoki Yoshida

The trained cGANs successfully reconstruct H{\alpha} emission from galaxies at a target redshift from observed, noisy intensity maps.

Noise reduction for weak lensing mass mapping: An application of generative adversarial networks to Subaru Hyper Suprime-Cam first-year data

no code implementations28 Nov 2019 Masato Shirasaki, Kana Moriwaki, Taira Oogi, Naoki Yoshida, Shiro Ikeda, Takahiro Nishimichi

We study the non-Gaussian information in denoised maps using one-point probability distribution functions (PDFs) and also perform matching analysis for positive peaks and massive clusters.

Single-epoch supernova classification with deep convolutional neural networks

no code implementations30 Nov 2017 Akisato Kimura, Ichiro Takahashi, Masaomi Tanaka, Naoki Yasuda, Naonori Ueda, Naoki Yoshida

Our method first builds a convolutional neural network for estimating the luminance of supernovae from telescope images, and then constructs another neural network for the classification, where the estimated luminance and observation dates are used as features for classification.
