Rank examples by attribute including duplicates

dandres

Is there an operator or combination of operators that will compute the rank of each example for a selected attribute?

The Sort/Generate ID method won't work here because some of the examples have the same value and thus should have the same rank.  The preference for those "ties" is to compute the lowest rank, not the average rank.

For example:

Value  Rank
100     1
98       2
97       3
97       3
96       5

Hi,

i don't know a one operator solution.

You can go for Sort, Generate ID and then use Aggregate and Group By your Value coloumn to calculate min(Id) and average(Value). Should work quite fine.
