The Cascading Analysts Algorithm
Summary: Cascading Analysts algorithm selects a small, disjoint set of segments on a product of trees to explain most metric change, mirroring a hierarchical analyst workflow. Applied in AdWords/Analytics; guarantees: optimal in 2D; log^(d-2)(n+1) for d>=3; 2-approx in ads; NP-hard via conflicts (lower bound 1.144^(d-2)). (summarized by gpt-5-nano on Feb 09 2026)
