Diego Ceccarelli commented on SOLR-10811: ----------------------------------------- Please note that QuickScorer is undergoing a patent process. http://learningtorank.isti.cnr.it > Speed up MultipleAdditiveTreesModel by using QuickScorer algorithm > ------------------------------------------------------------------ > > Key: SOLR-10811 > URL: https://issues.apache.org/jira/browse/SOLR-10811 > Project: Solr > Issue Type: Improvement > Security Level: Public(Default Security Level. Issues are Public) > Components: contrib - LTR > Reporter: Yuki Yano > Priority: Minor > Attachments: quickscorer_model.pdf, SOLR-10811_master.patch, > SOLR-10811.patch > > > QuickScorer is an algorithm which can calculate multiple additive trees fast > by using bitvectors for detecting target leaves. > It was first published in SIGIR 2015 and won the best paper award of the > conference. > refs: > http://zola.di.unipi.it/rossano/wp-content/papercite-data/pdf/sigir15.pdf > We implemented QuickScorer as one of LTRScoringModel. > This model uses same configuration of MultipleAdditiveTreesModel, thus it is > easy to replace the model. > Our experiments show our model can calculate scores about twice faster than > MultipleAdditiveTreesModel. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
