Machine learning of time series data using persistent homology

This study proposes a novel method for time-series analysis based on persistent homology. Traditional time-series analysis techniques based on persistent homology often involve high computational ...

Using cross-recurrence quantification analysis to compute similarity measures for time series of unequal length with applications to sleep stage analysis

A major challenge to quantifying similarities or relationships between two time series or sequences is that time-bound processes often do not have the same duration. This is particularly conspicuous ...
