When: Tuesday, May 6
Time: 12pm

Talk Title: "Learning in the presence of class imbalance"

>>>
>>> Models for knowledge discovery in the real world face the  
>>> pervasive and compelling problem of
>>> irregularities in data distribution. Decisions that are optimal in  
>>> expected utility can be vulner-
>>> able to catastrophic failure, and value functions that reflect the  
>>> discontinuities of the real world
>>> pragmatics can quickly become intractable. Surprises can happen in  
>>> uncertain environments. The
>>> class distributions may not be the same, with the class of  
>>> interest being rare. The training and
>>> testing distributions can differ. The costs of making mistakes or  
>>> benefits from making correct predictions
>>> may also not be constant and can evolve due to operational  
>>> reasons. In this talk, I will present
>>> our work on mining in the presence of unbalanced data, as  
>>> distributions shift.
