Large-scale matrix computation becomes essential for many data data applications, and hence the problem of sketching matrix with small space and high precision has received extensive study for the past few years. This problem is often considered in the row-update streaming model, where the data set is a matrix A -- Rn x d, and the processor receives a row (1 x d) of A at each timestamp. The goal is to maintain a smaller matrix (termed approximation matrix, or simply approximation) B -- Rl x d…

This work shows that sublinear space truly perfect sampling is impossible in the turnstile model, and proves a lower bound of Ω(min(n, log 1/γ) for any G-sampler with point-wise error γ from the true distribution, and gives a general time-efficient sublinear-space framework for developing truly perfect samplers in the insertion-only streaming and sliding window models.

This work observes that the symmetric norm streaming algorithm of Braverman et al.

This work introduces the problem of sampling from a moving window of recent items from a data stream and develops two algorithms, the first of which, "chain-sample", extends reservoir sampling to deal with the expiration of data elements from the sample and the second, "priority- sample", works even when the number of elements in the window can vary dynamically over time.
