HIFlow: Generating Diverse HI Maps and Inferring Cosmology while Marginalizing over Astrophysics using Normalizing Flows

Posted by klaurent October 6, 2021Tokyo

Kavli Affiliate: David N. Spergel | First 5 Authors: Sultan Hassan, Francisco Villaescusa-Navarro, Benjamin Wandelt, David N. Spergel, Daniel Anglés-Alcázar | Summary: A wealth of cosmological and astrophysical information is expected from many ongoing and upcoming large-scale surveys. It is crucial to prepare for these surveys now and develop tools that can efficiently extract most […]

Relative Entropy Gradient Sampler for Unnormalized Distributions

Posted by klaurent October 6, 2021Peking

Kavli Affiliate: Feng Yuan | First 5 Authors: Xingdong Feng, Yuan Gao, Jian Huang, Yuling Jiao, Xu Liu | Summary: We propose a relative entropy gradient sampler (REGS) for sampling from unnormalized distributions. REGS is a particle method that seeks a sequence of simple nonlinear transforms iteratively pushing the initial samples from a reference distribution […]

Derived categories of Quot schemes of locally free quotients via categorified Hall products

Posted by klaurent October 6, 2021Tokyo

Kavli Affiliate: Yukinobu Toda | First 5 Authors: Yukinobu Toda, , , , | Summary: We prove Qingyuan Jiang’s conjecture on semiorthogonal decompositions of derived categories of Quot schemes of locally free quotients. The author’s result on categorified Hall products for Grassmannian flips is applied to prove the conjecture. | Search Query: ArXiv Query: search_query=au:”Yukinobu […]
