ABBA: Adaptive Brownian bridge-based symbolic aggregation of time series
Steven Elsworth, Stefan Güttel
A new symbolic representation of time series, called ABBA, is introduced. It is based on an adaptive polygonal chain approximation of the time series into a sequence of tuples, fol…

Conversions between barycentric, RKFUN, and Newton representations of rational interpolants
Steven Elsworth, Stefan Güttel
We derive explicit formulas for converting between rational interpolants in barycentric, rational Krylov (RKFUN), and Newton form. We show applications of these conversions when wo…
