Variational Inference (VI) MCMC 的计算复杂度比较高,序列收敛的时间更长,但是 MCMC 本质上是一个渐进无偏估计 (asymptotically unbiased estimation),所以相对于 VI,MCMC 的精度更高。VI 使用一个简单分布拟合复杂的分布,必然会引入 bias,但是 VI 的效率很高,适合用在大规模计算中(比如 VAE,Variational AutoEncoder...
Bayes Inference: Summary Bayesian Inference delivers an integrated approach to: Inference – including “estimation” and “testing” Prediction – with a full accounting for uncertainty Decision – with likelihood and loss (these are distinct!) Bayesian Inference is conditional on available info. The...

Bayesian parameter estimation and Bayesian hypothesis testing present attractive alternatives to classical inference using confidence intervals and p value
Moreover, when xx is not a random variable, the problem is termed parameter estimation problem; if the variable is a random variable, the problem is usually termed parameter inference problem. Problems with ML and MAP It is known that ML is an unbiased. However, some times it is hard to...
Then, for each parameter, Bayesian inference learns a “posterior” distribution, through which we make a final estimation with a confidence interval. Bayesian inference can update the shape of the learned posterior distributions for model parameters whenever new data observations arrive, providing ...
Bayesian Estimation Inference 11.1 Introduction Bayesian procedures are becoming increasingly popular in building statistical models for real-world problems. In recent years, the Bayesian statistical methods have been increasingly used in scientific fields ranging from archeology to computing. Bayesian inference...
