Summary: Bug in recurrent layers when only returning final output
Key: SYSTEMML-1921
URL: https://issues.apache.org/jira/browse/SYSTEMML-1921
Project: SystemML
Issue Type: Bug
Reporter: Mike Dusenberry
Assignee: Mike Dusenberry
Currently, there is a typo in the {{backward}} functions of the recurrent
layers when {{given_sequences}} is false. Specifically, when only the final
time-step's output was desired from the forward functions, {{out}} and {{dout}}
will be of shape {{(N, M)}}, and within the {{backward}} functions, {{dout}}
will be padded with zeros for the earlier time-steps to enlarge the shape to
{{(N, T*M)}}. While the goal of the logic and the associated comments were
correct, there was a typo in which the shape was instead enlarged to {{(T*D)}}.
