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. (was: We should
