In this work, we investigate a method for aligning time series data represented in any metric space. The focus is on the stretching penalty, which is defined using the Hellinger kernel. To enhance the efficiency of this matching process, we propose the Elastic Time Warping algorithm. This innovative approach boasts a cubic complexity, making it a practical solution for handling large datasets. By leveraging the properties of the Hellinger kernel, our method aims to improve the accuracy of time series alignment, which is crucial in various applications such as finance, healthcare, and environmental monitoring. The algorithm's design ensures that it can adapt to the unique characteristics of the data, providing a robust framework for time series analysis.
