Automatic posterior transformation for likelihood-free inference

D Greenberg, M Nonnenmacher… - … on Machine Learning, 2019 - proceedings.mlr.press
How can one perform Bayesian inference on stochastic simulators with intractable likelihoods?
A recent approach is to learn the posterior from adaptively proposed simulations using …

Flexible statistical inference for mechanistic models of neural dynamics

…, K Öcal, M Nonnenmacher… - Advances in neural …, 2017 - proceedings.neurips.cc
Mechanistic models of single-neuron dynamics have been extensively studied in
computational neuroscience. However, identifying which models can quantitatively reproduce …

Training deep neural density estimators to identify mechanistic models of neural dynamics

…, JM Lueckmann, M Deistler, M Nonnenmacher… - Elife, 2020 - elifesciences.org

dynamical forecast systems. This study tests the applicability of springtime soil moisture (SM) …

A solution for the mean parametrization of the von Mises-Fisher distribution

M Nonnenmacher, M Sahani - arXiv preprint arXiv:2404.07358, 2024 - arxiv.org
The von Mises-Fisher distribution as an exponential family can be expressed in terms of either
its natural or its mean parameters. Unfortunately, however, the normalization function for …
