Using scaling-region distributions to select embedding parameters
Varad Deshmukh, Robert Meikle, Elizabeth Bradley +2
Reconstructing state-space dynamics from scalar data using time-delay embedding requires choosing values for the delay and the dimension . Both parameters are critical to th…
Towards automated extraction and characterization of scaling regions in dynamical systems
Varad Deshmukh, Elizabeth Bradley, Joshua Garland +1
Scaling regions -- intervals on a graph where the dependent variable depends linearly on the independent variable -- abound in dynamical systems, notably in calculations of invaria…
Using Curvature to Select the Time Lag for Delay Reconstruction
Varad Deshmukh, Elizabeth Bradley, Joshua Garland +1
We propose a curvature-based approach for choosing good values for the time-delay parameter in delay reconstructions. The idea is based on the effects of the delay on the geome…
Anomaly Detection in Paleoclimate Records using Permutation Entropy
Joshua Garland, Tyler R. Jones, Michael Neuder +3
Permutation entropy techniques can be useful in identifying anomalies in paleoclimate data records, including noise, outliers, and post-processing issues. We demonstrate this using…
