Parallelized Acquisition for Active Learning using Monte Carlo Sampling

1 code implementation30 May 2023 Jesús Torrado, Nils Schöneberg, Jonas El Gammal

Bayesian inference remains one of the most important tool-kits for any scientist, but increasingly expensive likelihood functions are required for ever-more complex experiments, raising the cost of generating a Monte Carlo sample of the posterior.

Active Learning Bayesian Inference

Fast and robust Bayesian Inference using Gaussian Processes with GPry

1 code implementation3 Nov 2022 Jonas El Gammal, Nils Schöneberg, Jesús Torrado, Christian Fidler

GPry does not need any pre-training, special hardware such as GPUs, and is intended as a drop-in replacement for traditional Monte Carlo methods for Bayesian inference.

Cosmological constraints on multi-interacting dark matter

no code implementations8 Oct 2020 Niklas Becker, Deanna C. Hooper, Felix Kahlhoefer, Julien Lesgourgues, Nils Schöneberg

The increasingly significant tensions within $\Lambda$CDM, combined with the lack of detection of dark matter (DM) in laboratory experiments, have boosted interest in non-minimal dark sectors, which are theoretically well-motivated and inspire new search strategies for DM.
