Much recent work has tried to extract this information through a range of different observables or via nonlinear transformations of the lensing field. Here we train and apply a 2D convolutional neural network to simulated noiseless lensing maps covering 96 different cosmological models over a range of {Ωm,σ8}. Using the area of the confidence contour in the {Ωm,σ8} plane as a figure-of-merit, derived from simulated convergence maps smoothed on a scale of 1.0 arcmin, we show that the neural network yields ≈5× tighter constraints than the power spectrum, and ≈4× tighter than the lensing peaks. Such gains illustrate the extent to which weak lensing data encode cosmological information not accessible to the power spectrum or even other, non-Gaussian statistics such as lensing peaks.","lang":"eng"}],"article_processing_charge":"No","_id":"17662","extern":"1","volume":97,"title":"Non-Gaussian information from weak lensing data via deep learning","author":[{"last_name":"Gupta","full_name":"Gupta, Arushi","first_name":"Arushi"},{"full_name":"Matilla, José Manuel Zorrilla","first_name":"José Manuel Zorrilla","last_name":"Matilla"},{"full_name":"Hsu, Daniel","first_name":"Daniel","last_name":"Hsu"},{"full_name":"Haiman, Zoltán","first_name":"Zoltán","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","last_name":"Haiman"}],"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","date_created":"2024-09-06T07:39:50Z","main_file_link":[{"url":" https://doi.org/10.48550/arXiv.1802.01212","open_access":"1"}],"status":"public","day":"18","issue":"10","language":[{"iso":"eng"}],"article_type":"original","date_published":"2018-05-18T00:00:00Z","article_number":"103515","date_updated":"2024-09-25T07:28:42Z","oa_version":"Preprint","citation":{"mla":"Gupta, Arushi, et al. “Non-Gaussian Information from Weak Lensing Data via Deep Learning.” Physical Review D, vol. 97, no. 10, 103515, American Physical Society, 2018, doi:10.1103/physrevd.97.103515.","ista":"Gupta A, Matilla JMZ, Hsu D, Haiman Z. 2018.
