Trend and Variable-Phase Seasonality Estimation from Functional Data
Liang-Hsuan Tai, Anuj Srivastava, Kyle A. Gallivan
The problem of estimating trend and seasonal variation in time-series data has been studied over several decades, although mostly using single time series. This paper studies the p…
Nonparametric Spherical Regression Using Diffeomorphic Mappings
Michael Rosenthal, Wei Wu, Eric Klassen +1
Spherical regression explores relationships between variables on spherical domains. We develop a nonparametric model that uses a diffeomorphic map from a sphere to itself. The rest…
A Two-Step Geometric Framework For Density Modeling
Sutanoy Dasgupta, Debdeep Pati, Anuj Srivastava
We introduce a novel two-step approach for estimating a probability density function (pdf) given its samples, with the second and important step coming from a geometric formulation…
