distribution Naive Bayes vs Full Bayes model classifiers

Jun 11, 2020· There's no clear definition of "Full Bayes" as a classifier. Most "real world" non-Naive Bayesian classifiers take into account some but not all dependencies between features. That is, they make independence assumptions based on the meaning of the features. If by "full Bayesian" you mean a joint model (as your example suggests), then one of the

Here’s why river overflow can lead to flood damage

Dec 28, 2020· Flood can be very terrifying if you live near rivers. Though called in much literature as a source of life, rivers can actually take lives when they overflow. Rivers carry many risks, especially when there is heavy rainfall and overtopping happens. When there is too much water because of very high volume of rainfall, water can burst the river banks, causing dry areas to be flooded.

Famous answer: Yes! (Robert Schapire in 1990) Solution: Create ensemble classifier HT(→x) = ∑T t = 1αtht(→x). This ensemble classifier is built in an iterative fashion. In iteration t we add the classifier αtht(→x) to the ensemble. At test time we evaluate all classifier and return the weighted sum.
