Tommaso Teofili created LUCENE-7823:
---------------------------------------
Summary: Have a naive bayes classifier which uses plain BM25
scores instead of plain frequencies
Key: LUCENE-7823
URL: https://issues.apache.org/jira/browse/LUCENE-7823
Project: Lucene - Core
Issue Type: Improvement
Components: modules/classification
Reporter: Tommaso Teofili
Assignee: Tommaso Teofili
Fix For: master (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.
