Full and accurate reconstruction of dynamics from time-series data - e.g., via delay-coordinate embedding - is a real challenge, but useful information can be gleaned from incomplete embeddings. We apply computational topology to a sequence of lower-dimensional embeddings of the data.Ìý Even though the full topology cannot be computed from these incomplete reconstructions, we conjecture that there are some results that can be computed from a SEQUENCE of such reconstructions, and that these are useful in time-series analysis.
