We propose normalizing flow regression (NFR), a novel offline inference method for approximating posterior distributions. Unlike traditional surrogate approaches that require additional sampling or inference steps, NFR directly yields a tractable posterior approximation through regression on existing log-density evaluations. We introduce training techniques specifically for flow regression, such as tailored priors and likelihood functions, to achieve robust posterior and model evidence estimation. We demonstrate NFR&#8217;s effectiveness on synthetic benchmarks and real-world applications from neuroscience and biology, showing superior or comparable performance to existing methods. NFR represents a promising approach for Bayesian inference when standard methods are computationally prohibitive or existing model evaluations can be recycled.<\/div>\n<p> \t<BR><br \/>\n <BR><\/BR><br \/>\n    Chengkun Li, Bobby Huggins, Petrus Mikkola, Luigi Acerbi<br \/>\n \t<BR><br \/>\n<BR><\/BR><br \/>\n<a href=\"https:\/\/arxiv.org\/abs\/2504.11554\">Go to original source<\/a><br \/>\n \t<BR><br \/>\n <BR><\/BR><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Normalizing Flow Regression for Bayesian Inference with Offline Likelihood Evaluations arXiv:2504.11554v1 Announce Type: new Abstract: Bayesian inference with computationally expensive likelihood evaluations remains a significant challenge in many scientific domains.
