             Summary: A bug in BPTTWorker::Backward() function with layers partially unrolled
in neuralnet
                 Key: SINGA-142
                 URL: https://issues.apache.org/jira/browse/SINGA-142
             Project: Singa
          Issue Type: Bug
            Reporter: Zheng Kaiping


This is in SINGA_HOME/src/work.cc, in “void BPTTWorker::Backward (int step, NeuralNet* net)
{}” function. It affects training in neuralnets with partially unrolled layers.

To be specific, there is no need to consider non-unrolled layers (i.e, without parameter sharing)
when aggregating gradients for parameters.
