Continuous Edit Distance, Geodesics and Barycenters of Time-varying Persistence Diagrams

Continuous Edit Distance (CED) is a significant advancement for developers working with time-varying persistence diagrams (TVPDs). This new metric combines local substitution costs with deletion and insertion penalties, allowing for better alignment and comparison of dynamic data. The two parameters, α and β, control the balance between temporal misalignment and diagram discrepancy, which can lead to improved clustering performance in real-life datasets.

For game developers, especially those involved in data analysis and algorithm development, the CED provides a principled approach to handling temporal data. The accompanying C++ implementation ensures reproducibility, making it easier for teams to integrate this method into their workflows. With its ability to recover temporal shifts and support pattern searches, CED could enhance gameplay analytics and user experience design significantly.
