[Paper Summary] Complete Parameter Inference for GW150914 Using Deep Learning
The paper describes a neural network architecture, based on normalizing flows alone, that is able to generate posteriors on the full $D = 15$ dimensional parameter space of quasi-circular binary inspirals, using input data surrounding the first observed GW event, GW150914, from multiple gravitational-wave detectors.

Bayes Inference, Bayes Factor, Model Selection
模型选择 (model selection) 是统计推断专题里一个很重要的话题。此文是于 2021.1.19 在 ITP-CAS 为 Journal Club 准备的一个整理与调研。算是自己对 model selection 在个人在当前理解程度上的一个记录。
