Joseph K. Bradley commented on SPARK-12363: ------------------------------------------- Thanks for identifying this. What do the predictions look like? Does it improve if you increase the number of iterations KMeans runs for when called from PIC? It seems like an intuitively reasonable test, but I could see it failing for bad initial cluster centers or if KMeans needs to run for more iterations. > PowerIterationClustering test case failed if we deprecated KMeans.setRuns > ------------------------------------------------------------------------- > > Key: SPARK-12363 > URL: https://issues.apache.org/jira/browse/SPARK-12363 > Project: Spark > Issue Type: Bug > Components: MLlib > Reporter: Yanbo Liang > > We plan to deprecated `runs` of KMeans, PowerIterationClustering will > leverage KMeans to train model. > I removed `setRuns` used in PowerIterationClustering, but one of the test > cases failed. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
