Streaming Complexity Separations for Dense and Sparse Graphs
Yang P. Liu, Hoai-An Nguyen, Noah G. Singer +1
We identify a sharp separation in the streaming space complexity of Maximum Cut when the algorithm must output an approximate cut (rather than only the approximate value). For dens…

Unbiased Insights: Optimal Streaming Algorithms for Sampling, the Forget Model, and Beyond
Honghao Lin, Hoai-An Nguyen, William Swartworth +1
We study sampling and frequency moment estimation in a single-pass insertion-only data stream. For , we present a nearly space-optimal approximate sa…

On Sketching Trimmed Statistics
Honghao Lin, Hoai-An Nguyen, David P. Woodruff
We study sketching trimmed statistics of a frequency vector, including the moment of the top- coordinates and of the trimmed- vector. Despite their natural role in robu…
