Bayesian updating
WebAug 24, 2024 · Model updating methods would calibrate these uncertain parameters in the FE model based on the measurement data, so called a data-driven model calibration. 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]. http://www.communicationcache.com/uploads/1/0/8/8/10887248/on_confirmation_bias_and_deviations_from_bayesian_updating.pdf

WebBayesian filtering allows us to predict the chance a message is really spam given the “test results” (the presence of certain words). Clearly, words like “viagra” have a higher chance of appearing in spam messages than in normal ones. Spam filtering based on a blacklist is flawed — it’s too restrictive and false positives are too great.
