Hi
I have a Multi class classification problem with 3 classes.Class 1 is being differentiated from other classes but I have a problem separating Class 2 from Class 0.(Most of the class 2 is being predicted as Class 0).Since there is a imbalance between these two classes (3:1) .I tried giving weights to Class 2 but then the model just classifies some of the Class 2 correctly but it also predicts Class 0 as Class 2 now, giving me the same accuracy when where was no weights given.
So any ideas on how to separate these two classes? I have tried NN, oneVSrest, also tried a bit of stacking with no significant gain.
