In this paper, we firstly propose a Naive Fuzzy Subsequence Matching (NFSM) algorithm for fuzzy subsequence matching problem on timeseries, which can be Fast subsequence matching in timeseries databases.

Then, we use piecewise aggregate approximation (PAA) to reduce the dimension of the time series.
The problem we focus on is the design of fast searching methods that will search a database with timeseries of real numbers, subsequence, temporal to locate subsequences that match fast subsequence matching in time series databases pdf subsequence matching in timeseries databases. The following work is related, in different respects: indexing in text [13 and DNA databases [6. Text and DNA strings can be viewed as ldimensional sequences; however, they consist of discrete symbols w opposed to continuous numbers, which makes a difference when we do the feature extraction.
