Forgive me if it’s too basic, I finish engineering a while ago. Given any time series, not periodic, I would like to find any repetitive pattern that is distinct (by some given measurement) and is unknown.
For example given this : I would like to find number 1 and 2( get their index on time).
- Is FFT going to help anyway?
- Without knowing or hard programming an algorithm, is it possible or do I need a serious machine learning?
(Are there practical books about finding patterns with code and not too much math?) Thanks.
