WebIn Bayesian statistics, the recent development of MCMC methods has made it possible to compute large hierarchical models that require integrations over hundreds to thousands of unknown parameters. [5] In rare event sampling, they are also used for generating samples that gradually populate the rare failure region. [citation needed] WebDec 13, 2024 · Naive Bayes performed the worst at 57.75% and we concluded that this was because the model has a harder time dealing with numerical data. Although kNN yielded the highest accuracy, the false-negative rate was quite high at 0.42 which means that there is a 42% probability that someone who is actually drowsy would be detected as alert by our …
