Mike Dusenberry reassigned SYSTEMML-1679: ----------------------------------------- Assignee: Mike Dusenberry (was: Fei Hu) > Add a new threshold utility function > ------------------------------------ > > Key: SYSTEMML-1679 > URL: https://issues.apache.org/jira/browse/SYSTEMML-1679 > Project: SystemML > Issue Type: Sub-task > Reporter: Mike Dusenberry > Assignee: Mike Dusenberry > > 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}}. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
