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. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
