BlazeIt: Optimizing Declarative Aggregation and Limit Queries for Neural Network-Based Video Analytics

Summary: BlazeIt brings declarative FrameQL and video-specific optimization to NN-based spatiotemporal analytics. It uses NNs as control variates for bounded-error approximate aggregates and introduces cardinality-limited search, achieving up to 83× speedups. (summarized by gpt-5.6-luna on Jul 24 2026)
