>
> The existing tests for maxpooling_backward always use dense data, which hides
> underlying correctness issues. These issues are due to invalid handling of
> empty sparse rows, empty ranges, and partial range entries with negative
> values. In all these cases, the maximum value is 0, which position determines
> the index for adding corresponding values.
