Hashing and sketching
Webrelated questions. Alon et al. (1999) showed a simple hashing-based algorithm for unbiased estima-tors for the Euclidean norm in the streaming setting. Charikar et al. (2004) showed an algorithm for the heavy-hitters problem based on the count sketch. Most relevant to our works is the count-min sketch of Cormode and Muthukrishnan (2005a; 2005b).
