Pattern Recognition

SID101098

Hello, 
I m trying to identify patterns in a time series data(please refer to the data below),in such a way that it tells me about the signature(s) (pattern it has in a particular period of time and therefore the algorithm extract those continuous time period in the form of 'from' and 'to' dates). Suppose my resultant attribute has values from 1-5. In the first half it has a value of 5 , then during second half value changes to 2 then again after some time the resultant attribute value becomes 5. So when we plot these on a graph(x-axis->resultant,y-axis->timeseries) we will see two signature (profile,pattern) ie pattern 1- value 5 and pattern 2- value 2. In a way the output should be like

"From". " To " . "Profile"
Can anyone help
