Consistent and Flexible Selectivity Estimation for High-Dimensional Data

Summary: Deep-learning-based selectivity estimation learns a query-dependent piecewise-linear function whose output is guaranteed to be non-decreasing in the threshold. To scale to high-dimensional data, the method partitions the dataset into disjoint subsets and trains local models, achieving superior accuracy and efficiency over state-of-the-art approaches on real data.
