Efficiently Answering Durability Prediction Queries
Junyang Gao, Yifan Xu, Pankaj K. Agarwal +1
We consider a class of queries called durability prediction queries that arise commonly in predictive analytics, where we use a given predictive model to answer questions about pos…
Selecting Data to Clean for Fact Checking: Minimizing Uncertainty vs. Maximizing Surprise
Stavros Sintos, Pankaj K. Agarwal, Jun Yang
We study the optimization problem of selecting numerical quantities to clean in order to fact-check claims based on such data. Oftentimes, such claims are technically correct, but…
Learning to Sample: Counting with Complex Queries
Brett Walenz, Stavros Sintos, Sudeepa Roy +1
We study the problem of efficiently estimating counts for queries involving complex filters, such as user-defined functions, or predicates involving self-joins and correlated subqu…
