新的 Rènyi 正则化变分推断方法应对模型校准挑战

研究人员开发了一种名为基于 Rènyi 正则化的流模型变分推断的新方法,以改进贝叶斯模型校准,特别是在后验分布具有多个不同模式的情况下。该技术引入了基于 Rènyi 散度的正则化项,以鼓励近似后验更好地覆盖先验支持,旨在解决变分推断中的模式崩溃问题。虽然正则化减少了接近崩溃的发生,但它在近似精度方面带来了权衡,并且不能完全解决模式崩溃问题。 AI

影响 引入了一种新颖的变分推断正则化技术,有可能在复杂场景下提高贝叶斯模型校准的准确性。

    R\`enyi-Regularized Flow-Based Variational Inference for Bayesian Calibration

    arXiv:2610.37169v1 Announce Type: new Abstract: Variational inference with normalizing flows provides a flexible posterior approximation for Bayesian model calibration, but struggles when the posterior has several modes separated by regions of low probability mass. We study this …
