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…
A Semi-Parametric Torus-to-Torus Regression Model with Geometric Loss: Application to Cyclone Data
Surojit Biswas, Buddhananda Banerjee
This study introduces a novel torus-to-torus regression framework to improve the analysis and prediction of cyclone-driven wind-wave directional dynamics. This research, to our kno…
Change-point problem: Direct estimation using a geometry inspired identifiable reparameterization
Buddhananda Banerjee, Arnab Kumar Laha
Estimation of mean shift in a temporally ordered sequence of random variables with a possible existence of change-point is an important problem in many disciplines. In the availabl…
Semi-parametric least-area linear-circular regression through Möbius transformation
Surojit Biswas, Buddhananda Banerjee
This paper introduces a novel regression model designed for angular response variables with linear predictors, utilizing a generalized Möbius transformation to define the regressio…
