UDDSketch: Accurate Tracking of Quantiles in Data Streams
Italo Epicoco, Catiuscia Melle, Massimo Cafaro +2
We present UDDSketch (Uniform DDSketch), a novel sketch for fast and accurate tracking of quantiles in data streams. This sketch is heavily inspired by the recently introduced DDSk…

Distributed mining of time--faded heavy hitters
Marco Pulimeno, Italo Epicoco, Massimo Cafaro
We present \textsc{P2PTFHH} (Peer--to--Peer Time--Faded Heavy Hitters) which, to the best of our knowledge, is the first distributed algorithm for mining time--faded heavy hitters…
