Solving the Cosmic Coincidence Problem: The Locally Pumped Dark Energy Model
Carlo R. Contaldi, Mauro Pieroni
We propose the Locally Pumped Dark Energy (LPDE) mechanism in which cosmic acceleration is triggered by the emergence of non-linear dark matter structure. In an effective-field-the…

Simulation-based inference with deep ensembles: Evaluating calibration uncertainty and detecting model misspecification
James Alvey, Carlo R. Contaldi, Mauro Pieroni
Simulation-Based Inference (SBI) offers a principled and flexible framework for conducting Bayesian inference in any situation where forward simulations are feasible. However, vali…

Dynamic SBI: Round-free Sequential Simulation-Based Inference with Adaptive Datasets
Huifang Lyu, James Alvey, Noemi Anau Montel +2
Simulation-based inference (SBI) is emerging as a new statistical paradigm for addressing complex scientific inference problems. By leveraging the representational power of deep ne…
