Bayesian Methods
Statistical methods that perform inference starting from a posterior distribution over parameters. In deep learning, uncertainty estimation is achieved through techniques such as MC Dropout and Bayesian neural networks. The approach is theoretically elegant but entails relatively high computational cost.

Flagsmith Experiments uses a Bayesian approach for variant evaluation, outputting the probability that one variant is better than another.
The Bayesian approach allows continuous observation during an experiment without worrying about type I error inflation caused by "peeking".
贝叶斯方法(如 MC Dropout、贝叶斯神经网络)从参数后验分布出发,通过多次随机前向传播采样来近似预测分布。
分位数回归、集成学习和贝叶斯方法三种不确定性估计路径各有取舍:分位数回归计算最省,集成学习实现简单但训练成本高,贝叶斯方法理论最优雅但收敛慢。
Methods for addressing measurement error include using multiple measurements or instrumental variables, and employing error-correction models or Bayesian methods to explicitly model the error.
Bayesian methods can use historical failure rates as a prior and combine them with new observations to update the posterior distribution, conservatively estimating true risk when samples are scarce
The authors note that this significance may be affected by the small sample size and multiple comparisons, and could be due to chance.
贝叶斯方法在20世纪90年代曾被神经网络热潮边缘化,但其理论价值在后来的深度学习不确定性量化中得到重新认可
