Unbiased Insights: Optimal Streaming Algorithms for l_p Sampling, the Forget Model, and Beyond
Summary: Nearly space-optimal single-pass ℓp samplers, including continuous sampling, improve p=2 bounds and attain optimality for p<2. They enable near-unbiased Fp estimation under forget and suffix-prefix deletions, resolving PODS’24 open problems and extending to entropy and coordinate-wise contractions.
