Summary:
Barycentric coordinates are first used in Mees, Int. J. Bifurcat. Chaos (1991) to model a short nonlinear time series faithfully, while his formulation is restricted to low-dimensional dynamics because it employs triangulation. We recently relaxed his formulation by using linear programming (Hirata et al., Chaos (2015)). Using this relaxation, we can generate prediction and freeruns from a high dimensional time series. In this talk, we will review these recent advancements on barycentric coordinates and discuss some indices that evaluate locally the modelling accuracy for barycentric coordinates.
