Geometry-Adaptive Clustering on High-Dimensional Tori
Surojit Biswas, Soumyadip Paik, Buddhananda Banerjee
Multivariate angular data lie on a torus, but clustering methods often use the flat torus. We introduce curved-torus energy (CTE), a position-dependent dissimilarity based on restr…
Distribution-Free test for Changepoint Detection in Angular Mean Direction: Application in Finance
Surojit Biswas, Buddhananda Banerjee
In this paper, we propose a distribution-free test for detecting changepoint in the mean direction of angular data. The uncertainty in angular measurements is quantified through th…
Hyperbolic statistical inference for Treatment Effects with Circular biomarker of astigmatism
Buddhananda Banerjee, Surojit Biswas, Daitari Prusty
Circular biomarkers arise naturally in many biomedical applications, particularly in ophthalmology, where angular measurements such as astigmatism are routinely recorded. Similar d…
