[jira] [Commented] (SPARK-13733) Support initial weight distribution in personalized PageRank
[ https://issues.apache.org/jira/browse/SPARK-13733?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=15207219#comment-15207219 ] Gayathri Murali commented on SPARK-13733: - [~mengxr] [~dwmclary] https://issues.apache.org/jira/browse/SPARK-5854 - mentions one key difference between page rank and personalized page rank as: "In PageRank, every node has an initial score of 1, whereas for Personalized PageRank, only source node has a score of 1 and others have a score of 0 at the beginning.", which basically means we initialize as [1, 0, 0, 0, ..] where we set 1 only to the seed node. For this JIRA, do we want to instead set an initial distribution of weights such that all nodes receive non-zero initial values? Could you clarify if this is the behavior that is intended? > Support initial weight distribution in personalized PageRank > > > Key: SPARK-13733 > URL: https://issues.apache.org/jira/browse/SPARK-13733 > Project: Spark > Issue Type: New Feature > Components: GraphX >Reporter: Xiangrui Meng > > It would be nice to support personalized PageRank with an initial weight > distribution besides a single vertex.
