Neutrino propagation in the Earth and emerging charged leptons with $\texttt{nuPyProp}$

NuSpaceSim/nupyprop 30 Sep 2022

The $\texttt{nuPyProp}$ outputs are lookup tables of charged lepton exit probabilities and energies that can be used directly or as inputs to the $\texttt{nuSpaceSim}$ code designed to simulate optical and radio signals from extensive air showers induced by the emerging charged leptons.

Lossless, Scalable Implicit Likelihood Inference for Cosmological Fields

tlmakinen/cosmicgraphs 15 Jul 2021

We find that a) summaries obtained from convolutional neural network compression do not lose information and therefore saturate the known field information content, both for the Gaussian covariance and the lognormal cases, b) simulation-based inference using these maximally informative nonlinear summaries recovers nearly losslessly the exact posteriors of field-level inference, bypassing the need to evaluate expensive likelihoods or invert covariance matrices, and c) even for this simple example, implicit, simulation-based likelihood incurs a much smaller computational cost than inference with an explicit likelihood.
