Yet, despite these advances increasing awareness relation to—for example, gender, race, class, d...

Bagging is one of the most effective computationally intensive procedures to improve on unstable estimators or classifiers, useful especially for high dimensional data set problems. Here we formalize the notion of instability and derive theoretical results to analyze the variance reduction effect of bagging (or variants thereof) in mainly hard decision problems, which include estimation after t...

There is currently great interest in building information mediators that can integrate information from multiple data sources such as database systems or Web sources. An issue in building information mediators is how to make them responsive given the high response time for retrieving data from the data sources being integrated, which are databases or Web servers residing remotely. We present an...
