haojin2 edited a comment on issue #14842: Implementation for equivalence of tf.moments URL: https://github.com/apache/incubator-mxnet/pull/14842#issuecomment-489521394 @eric-haibin-lin The op gives variance of the input on arbitrary axis/axes, so it's technically the `np.var` operator's equivalence with an extra `mean` output. The impl of this op could also become the common helper function for various versions of normalizations. Plus: My current work on group norm is depending on the impl of this op or I'll have to write the same impl twice within the operator.
