Subject [jira] [Commented] (HAMA-651) Create a gradient descent BSP
Date Sun, 07 Oct 2012 07:47:04 GMT

    [ https://issues.apache.org/jira/browse/HAMA-651?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13471171#comment-13471171

Thomas Jungblut commented on HAMA-651:
--------------------------------------

Good. Just a tiny suggestion: I would extract an costfunction interface that can be supplied
from outside and reflectively instantiated in your BSP.
Subclassing an algorithm is not so good for everybody.
