Hello @vikasraykar!
Thank you for posting this issue. I think it's possible. Do you have any paper in mind that provides some details about this algorithm? I wonder how to set constraints for the aggregation to output Pr[yi > c1] > Pr[yi > c2] in case when c1 < c2. I'm not sure this constraint will be satisfied if we just run, for instance, separate DS aggregations for each of the binary classification tasks.

Is it possible to support aggregation of ordinal labels as a part of this toolkit via this reduction algorithm.
