Reduced-Rank Tensor-on-Tensor Regression and Tensor-variate Analysis of Variance
Carlos Llosa-Vite, Ranjan Maitra
Fitting regression models with many multivariate responses and covariates can be challenging, but such responses and covariates sometimes have tensor-variate structure. We extend t…
An Efficient -modes Algorithm for Clustering Categorical Datasets
Karin S. Dorman, Ranjan Maitra
Mining clusters from data is an important endeavor in many applications. The -means method is a popular, efficient, and distribution-free approach for clustering numerical-value…
CatSIM: A Categorical Image Similarity Metric
Geoffrey Z. Thompson, Ranjan Maitra
We introduce CatSIM, a new similarity metric for binary and multinary two- and three-dimensional images and volumes. CatSIM uses a structural similarity image quality paradigm and…
Estimating Basis Functions in Massive Fields under the Spatial Mixed Effects Model
Karl T. Pazdernik, Ranjan Maitra
Spatial prediction is commonly achieved under the assumption of a Gaussian random field (GRF) by obtaining maximum likelihood estimates of parameters, and then using the kriging eq…
Multi-layered characterization of hot stellar systems with confidence
Souradeep Chattopadhyay, Steven D. Kawaler, Ranjan Maitra
Understanding the physical and evolutionary properties of Hot Stellar Systems (HSS) is a major challenge in astronomy. We studied the dataset on 13456 HSS of Misgeld and Hilker (20…
