Subject [jira] [Updated] (SYSTEMML-1679) Add a new threshold utility function
Date Fri, 16 Jun 2017 00:13:00 GMT

     [ https://issues.apache.org/jira/browse/SYSTEMML-1679?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Mike Dusenberry updated SYSTEMML-1679:
--------------------------------------
    Description: 
We should add a new {{threshold}} utility function (in {{nn/util.dml}}) that accepts a matrix
{{X}} and a threshold parameter {{thresh}} and returns an indicator matrix {{out}} with values
in \{0, 1\} depending on whether or not the values in {{X}} are above {{thresh}}.  We could
use this, for example, for determining the predicted class in a binary classification problem
given the output of a sigmoid layer.

We should also add a test case in {{nn/test/test.dml}}.
