Current implementation of average() is confusing when compared with sum().
Both sum() and average() do not take axis, and perform similar operations.
However, the semantics of their output is different -
- sum() acts over the dimensions other than batch size
- average() acts over the batch size

To avoid this confusion, average is provided with axis argument with 0 as default.
This is now analogous to sum(axis) than sum()
