Altair EmployeeHi,
can you please check with a break point if the data set contains positive and negative examples after upsampling?

OPNo there are no positive or negative samples. The target label is binominal and contains 2 classes 'At Risk' and 'Good Standing'
Appreciate your support

Altair EmployeeHi,
thats usually ment by "positive' and "negative". Did you check that you have enough At Risk and Standing examples?
