Bayesian Neural Network
An approach that incorporates Bayesian inference into neural networks by placing probability distributions over network weights rather than using point estimates. This enables systematic quantification of epistemic uncertainty and is suited to settings involving scarce data or high-stakes decision making.
Timeline (last 90 days)
Common implementation methods for uncertainty estimation include Monte Carlo Dropout, deep ensembles, and Bayesian neural networks.
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。
The arXiv paper (arXiv:2610.09132v1) studies the prior dominance phenomenon that occurs as width increases in Bayesian neural networks.
As network width M increases, the KL term grows linearly with the number of parameters while the expected log-likelihood term grows relatively more slowly, which is the fundamental mathematical cause of the prior dominance phenomenon.
