URL: https://github.com/apache/incubator-mxnet/issues/11941
 
 
   when i read the paper <<LDMNet: Low Dimensional Manifold Regularized Neural Networks>>,
   https://arxiv.org/abs/1711.06246?context=cs
    i got a different regularization iterm which come from the output feature of middle layer Relu. i know it is not like the weight decay , and i have to modify the backward of the gradient, but how to do this ?
