ASF GitHub Bot commented on FLINK-1807: --------------------------------------- Github user tillrohrmann commented on the pull request: https://github.com/apache/flink/pull/613#issuecomment-99065857 That's a good question. I can't really tell because in the log4j-test.properties of the flink-ml module the logging is set to OFF. Apparently, the problem only occurs for the hadoop-1 profiles. > Stochastic gradient descent optimizer for ML library > ---------------------------------------------------- > > Key: FLINK-1807 > URL: https://issues.apache.org/jira/browse/FLINK-1807 > Project: Flink > Issue Type: Improvement > Components: Machine Learning Library > Reporter: Till Rohrmann > Assignee: Theodore Vasiloudis > Labels: ML > > Stochastic gradient descent (SGD) is a widely used optimization technique in > different ML algorithms. Thus, it would be helpful to provide a generalized > SGD implementation which can be instantiated with the respective gradient > computation. Such a building block would make the development of future > algorithms easier. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
