Time Series Averaging under Dynamic Time Warping

Problem:

Find an optimizer which minimizes the Fréchet function “as good as possible” for samples from many datasets.

ToDo

  • Alternative Optimizer suchen
    - == Frechet function minimizer
    - reine nonsmooth analysis?
    - geeignet für Frechet?
    - gibt es eine Veröffentlichung dazu?
    - öffentliche Implementation verfügbar?
  • Benchmark designen
  • Paper schreiben

Irrelevant (since they're already considered in the original paper)

  • Majorize-Minimize Mean Algorithm
  • DTW Barycenter Averaging (seems to be equivalent to MM ??? )
