Abstract
One embodiment is a method that generates points from an input space obtained from a query for a database. A kernel function maps the points from the input space to a feature space. Given a point in the feature space, a reverse mapping identifies coordinates in the input space for the point to predict performance of the query before the query executes in the database.
