On Functional Aggregate Queries with Additive Inequalities
Summary: Introduces FAQ-AI (functional aggregate queries with additive inequalities) and relaxed tree decompositions/widths, enabling faster Boolean evaluation by extending InsideOut with Chazelle's semigroup range-search. Defines counting submodular width (#subw) between submodular and fractional hypertree widths to bound runtimes and gives faster in-database algorithms for k-means, linear SVM, and non-polynomial-loss training than materializing joins.
