[jira] [Commented] (SPARK-9129) Integrate convolutional deep belief networks for visual recognition tasks

    [ https://issues.apache.org/jira/browse/SPARK-9129?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14641308#comment-14641308 ] 

Joseph K. Bradley commented on SPARK-9129:
------------------------------------------

There have been long ongoing discussions about adding deep learning to MLlib, most of which are linked to [SPARK-2352].  Could you please check the JIRAs and PRs linked there?  If you agree, I'd like to close this to focus discussion on those older JIRAs.  Thanks!

> There has been much interest in unsupervised learning of hierarchical generative models such as deep belief networks. Scaling such models to full-sized, high-dimensional images remains a difficult problem. Some users complain about the performance and convergence speed of a model. Integrate this to create a new usage for Spark in visual related tasks.
