TL;DR
本文提出了一种黑盒变分推理方法——变分 boosting,通过迭代优化来逼近一个越来越丰富的逼近类,从而扩展其变分逼近类,应用于合成和真实的统计模型,表明通过比较精确和有效地后验推理,其结果优于现有的后验逼近算法。
Abstract
We propose a
black-box variational inference
method to approximate intractable distributions with an increasingly rich approximating class. Our method, termed
variational boosting
, iteratively refines an existing
