-----------------------------
Summary: Fix a bug in InnerProductLayer caused by weight matrix
sharing
Key: SINGA-116
URL: https://issues.apache.org/jira/browse/SINGA-116
Project: Singa
Issue Type: Bug
Reporter: wangwei
Assignee: wangwei
There is a bug in the implementation of InnerProductLayer, which appears when
training the auto-encoder example.
The weight matrix in inner-product layer in the encoder is shared by another
layer in the decoder. But the decoder uses transposed version.
The current code does not handle matrix transposition.
The bug can be fixed considering the transpose_ field explicitly.
We may later handle it implicitly using a Tensor class that handles
transposition automatically.
