Approximating time series¶
Approximation algorithms try to capture the most important information from time series. They can be seen as simple feature extraction algorithms.
Bag-of-words transformation¶
Bag-of-words algorithms transform a sequence of symbols into a bag of words.
Classification algorithms¶
