On Wednesday april 6, guest professor Szymon Jaroszewicz from the Institute of Computer Science of the Polish Academy of Sciences, and the National Institute of Telecommunications in Poland, will give an invited presentation on "Decision trees for uplift modeling" at 4pm in room G.006.

Abstract:
Traditional classification models predict the probability that an object belongs to a given class. In many cases, such as clinical trials or direct marketing, some action is to be taken based on model's predictions. In such a case one wants, instead, to model the difference between class probabilities in the case when the action is taken and the case when the action is not taken. Such a model, called an 'uplift model' makes it possible to find individuals for which the action is most profitable. This talk will give an overview of uplift modeling and present author's recent contributions to building uplift decision trees.
