Elastic $k$-means clustering of functional data for posterior exploration, with an application to inference on acute respiratory infection dynamics

2020 · arXiv (Cornell University)

We propose a new method for clustering of functional data using a $k$-means framework. We work within the elastic functional data analysis framework, which allows for decomposition of the overall variation in functional data into …

Distribution on Warp Maps for Alignment of Open and Closed Curves

2017 · arXiv (Cornell University)

Alignment of curve data is an integral part of their statistical analysis, and can be achieved using model- or optimization-based approaches. The parameter space is usually the set of monotone, continuous warp maps of a …
