ASF subversion and git services commented on SOLR-13589: -------------------------------------------------------- Commit 2f6a681b3960bdf16426db89359f4484d58bdee3 in lucene-solr's branch refs/heads/master from Joel Bernstein [ https://gitbox.apache.org/repos/asf?p=lucene-solr.git;h=2f6a681 ] SOLR-13589: Allow zplot to visualize clusters and convex hulls > Allow zplot to visualize 2D clusters and convex hulls > ----------------------------------------------------- > > Key: SOLR-13589 > URL: https://issues.apache.org/jira/browse/SOLR-13589 > Project: Solr > Issue Type: New Feature > Security Level: Public(Default Security Level. Issues are Public) > Components: streaming expressions > Reporter: Joel Bernstein > Priority: Major > Attachments: SOLR-13589.patch, SOLR-13589.patch, clusters.png, > convex.png > > > This ticket will add support for visualization of convex hulls through the > projectToBorder function and 2D clusters by adding the clusters parameter to > the zplot function. > The *projectToBorder* function is a function that works together with the > existing *convexHull* function. It takes two parameters: > 1) A Convex Hull created by the *convexHull* function. > 2) A matrix of 2D points to project to the border. > The projectToBorder function then projects each 2D point to the Convex Hull > border and returns a matrix with these points. > Using this approach the border of a convex hull can be visualized in > interesting ways. > Sample visualizations are attached. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
