Diffusion posterior sampling for simulation-based inference in tall data settings

1 code implementation11 Apr 2024 Julia Linhart, Gabriel Victorino Cardoso, Alexandre Gramfort, Sylvain Le Corff, Pedro L. C. Rodrigues

Determining which parameters of a non-linear model could best describe a set of experimental data is a fundamental problem in science and it has gained much traction lately with the rise of complex large-scale simulators (a. k. a.

L-C2ST: Local Diagnostics for Posterior Approximations in Simulation-Based Inference

1 code implementation NeurIPS 2023 Julia Linhart, Alexandre Gramfort, Pedro L. C. Rodrigues

Building upon the well-known classifier two-sample test (C2ST), we introduce L-C2ST, a new method that allows for a local evaluation of the posterior estimator at any given observation.

Validation Diagnostics for SBI algorithms based on Normalizing Flows

no code implementations17 Nov 2022 Julia Linhart, Alexandre Gramfort, Pedro L. C. Rodrigues

Building on the recent trend of new deep generative models known as Normalizing Flows (NF), simulation-based inference (SBI) algorithms can now efficiently accommodate arbitrary complex and high-dimensional data distributions.
