[GitHub] rayjs opened a new issue #9328: Row wise normalization of tensor

rayjs opened a new issue #9328: Row wise normalization of tensor
URL: https://github.com/apache/incubator-mxnet/issues/9328
 
 
   Hi,
   I am new to mshadow. I am seeking some help regarding a tensor operation. I see there are examples to implement elementwise tensor operations as below:
   https://github.com/dmlc/mshadow/tree/3d87ed2a4b47ef749c616f208cee45d920fb6e6e/guide#user-defined-operator
   
   But I am looking for slightly different that is, row wise normalization of a tensor
   A= [row1; row2;... rowN]; Anormalized = [row1/norm(row1); ....; rowN/norm(rowN)];
   norm refers to the 2-norm.
   This can be also thought of as reduction and then broadcast along the rows of the tensor.
   I want to have an function like Tensor out = dot(A,B);
   Is there any implementation or any pointer would be helpful?
