Sebastian Schelter resolved GIRAPH-480. --------------------------------------- Resolution: Fixed Fix Version/s: 0.2.0 > Add convergence detection to org.apache.giraph.examples.RandomWalkVertex > ------------------------------------------------------------------------ > > Key: GIRAPH-480 > URL: https://issues.apache.org/jira/browse/GIRAPH-480 > Project: Giraph > Issue Type: Improvement > Components: examples > Affects Versions: 0.2.0 > Reporter: Sebastian Schelter > Assignee: Sebastian Schelter > Fix For: 0.2.0 > > > I propose to add convergence detection to the RandomWalkVertex. Convergence > is achieved when the overall absolute change (L1 norm) of the difference > between the current and the previous probability vector becomes less than a > given threshold. Convergence detection can be implemented via an additional > aggregator and a check in the master compute function. > This change would make the class much easier to use as the users don't have > to worry about the number of supersteps to execute, but can simply specify a > high number as MAX_SUPERSTEPS and be sure that the algorithm convergences > when acceptable quality of the result is reached. -- This message is automatically generated by JIRA.
