Sketching Probabilistic Data Streams
Summary: First sublinear-space, sublinear-time algorithms for aggregating probabilistic data streams under possible-worlds semantics. Introduces concise streaming sketches extending conventional sketching to probabilistic streams to approximate distributions of complex aggregates (distinct counts, joins) with randomized guarantees.
