Abstract:
Data streams are one of the
most relevant new data sources, they refer to flows of
data that come at a very high rate. Let us consider a stock-exchange
market, where n different
stocks with p considered attributes (e.g. price, quantity, seller/buyer
id, . . .) are negotiated all
day long. The distinguishing feature in data streams analysis is
that the focus is on transient
relations. The present paper proposes a visualization tool exploiting
Multidimensional Data
Analisis (MDA) techniques to represent the evolving association structures
among attributes over different time-frames. The general
aim is to detect the stability of the deviation from indipendence
in the occurrence of an observed set of attributes stored as binary
stream.
