A Learned Cuckoo Filter for Approximate Membership Queries over Variable-sized Sliding Windows on Data Streams
Summary: Introduces Learned Cuckoo Filter (LCF) for approximate membership queries on data streams with variable sliding windows, using a trained oracle to adaptively maintain cuckoo filters. Offers compact LCF_C and theoretical LCF_O with space-accuracy guarantees; experiments show 61% space savings and 12x accuracy gains at the same space. (summarized by gpt-5-nano on Feb 09 2026)
