pattern recognition in a time series <p>I understand that the question I am asking seem the be somewhat related to another question which has been asked already <a href="http://dsp.stackexchange.com/questions/966/pattern-recognition-for-temporal-data">here</a> and <a href="http://stackoverflow.com/questions/11752727/pattern-recognition-in-time-series">here</a>. </p> <p>But I feel that this is an entirely different question. (I have also <a href="http://dsp.stackexchange.com/questions/19896/pattern-recognition-in-a-time-series">submitted this question</a> on the dsp.stackexchange)</p> <p>I have a huge (over 100K data points) time series data of the position (x, y coordinates) of an element in space. This element is vibrating randomly, and both amplitude and the frequency of vibration is random. I want to look at the events which are similar and see if there is any pattern in those events, are they periodic or related somehow.</p> <p>I am working on a biological problem and have very little knowledge about signal processing. I can provide more details. Any help would be really appreciated.</p>
