Abstract
The search for mining weak periodic patterns in time series data is an
active topic. Given the fact that rarely a real world dataset is perfectly
periodic, the coming presentation will introduce some efficient approaches
for mining partial periodic patterns.
Given some period length, several algorithms for finding partial periodic
patterns, by exploring some interesting properties related to partial
periodicity, such as the Apriori property and the max-subpattern hit set
peroperty, are presented. These algorithms needs only two scans over the
time series data. Further, some method also are presebted to discover
approximate and partial periodicities, when no period length is known in
advance.
