[jira] [Commented] (LUCENE-7823) Have a naive bayes classifier
which uses plain BM25 scores instead of plain frequencies

> Reporter: Tommaso Teofili

> Fix For: 7.0

>
> {{SimpleNaiveBayesClassifier}} users term frequencies with add one smoothing to calculate likelihood and just tf for prior. Given Lucene has switched to BM25 it would be better to have a different impl which uses BM25
> scoring as a probability measure of both prior and likelihood.
