-----------------------------
Summary: Add base Layer class for V1.0
Key: SINGA-169
URL: https://issues.apache.org/jira/browse/SINGA-169
Project: Singa
Issue Type: New Feature
Reporter: wangwei
The new Layer class provides similar functionality as that in V0.3, i.e., store
parameters, and perform feature transformation and compute gradients of
parameters.
The difference is that we change the signature/API of
ComputeFeature/ComputeGradient. Now we accept features as arguments and return
the transformed feature as outputs for Forward (corresponding to the
ComputeFeature function in v0.3). We accept gradients as arguments and return
the gradients of lower layers and parameters as return values for Backward
function (corresponding to the ComputeGradient function in v0.3).
