Estimating Class Counts in Unlabeled Data
Wednesday, November 5, 2014 - 3:00pm to 4:00pm
Jerome H. Friedman, Professor of Statistics, Stanford University

The problem of estimating the fraction of positive examples in a future unlabeled data set using a regression model trained on past labeled data is studied. It is shown that if the training data fraction is substantially different than that of the future sample then the straightforward estimate can be highly biased.
