WitrynaThe Naive Bayes classification algorithm is a probabilistic classifier. It is based on probability models that incorporate strong independence assumptions. The independence assumptions often do not have an impact on reality. Therefore they are considered as naive. You can derive probability models by using Bayes' theorem … Witryna"We use a Naive Bayes classifier..." Naive Bayes is very popular in spam filtering. – Almost as accurate in SF as SVMs, AdaBoost, etc. – Much simpler, easy to understand and implement. – Linear computational and memory complexity. But there are many NB versions.Which one? – Bayes' theorem + naive independence assumptions. – …
