CR-precis: A deterministic summary structure for update data streams

  title={CR-precis: A deterministic summary structure for update data streams},
  author={Sumit Ganguly and Anirban Majumder},
We present deterministic sub-linear space algorithms for a number of problems over update data streams, including, estimating frequencies of items and ranges, finding approximate frequent items and approximate φ-quantiles, estimating inner-products, constructing nearoptimal B-bucket histograms and estimating entropy. We also present new lower bound results for several problems over update data streams.
