WebBayesian statistics is centered on constructing certain assumptions about how the probability of an event is distributed, and then adjusting that belief as new information comes in. It can be more involved to construct a Bayesian model as opposed to the “look at many things in aggregate” approach used in frequentist statistics. WebBy equivalently transforming the Bayesian updating problem under the observation uncertainty into a reli-ability analysis problem involving interval and random variables, a new Bayesian updating model is established. A sin-gle-layer and a double-layer Kriging algorithms for estimating the established model are proposed, which can efficiently ...

One type of model updating method is based on Bayesian theory, which tries to find a probability distribution function (PDF) of the model parameters [1,2,3,4,5,6,7,8,9,10,11].
WebBayesian Inference. In a general sense, Bayesian inference is a learning technique that uses probabilities to define and reason about our beliefs. In particular, this method gives us a way to properly update our beliefs when new observations are made. Let’s look at this more precisely in the context of machine learning. WebApr 14, 2024 · In this case, the likelihood function used in the Bayesian updating would need to be adjusted accordingly. The extension of the proposed method to other types of CCs and non-normal distributions can improve the effectiveness and efficiency of quality control processes in various industries, such as healthcare, finance, and manufacturing.
