Classification Using Global and Local Mahalanobis Distances
Annesha Ghosh, Anil K. Ghosh, Rita SahaRay +1
We propose a novel semiparametric classifier based on Mahalanobis distances of an observation from the competing classes. Our tool is a generalized additive model with the logistic…
Nearest Neighbor Classification based on Imbalanced Data: A Statistical Approach
Anvit Garg, Anil K. Ghosh, Soham Sarkar
When the competing classes in a classification problem are not of comparable size, many popular classifiers exhibit a bias towards larger classes, and the nearest neighbor classifi…
On Exact Feature Screening in Ultrahigh-dimensional Binary Classification
Sarbojit Roy, Soham Sarkar, Subhajit Dutta +1
We propose a new model-free feature screening method based on energy distances for ultrahigh-dimensional binary classification problems. With a high probability, the proposed metho…
Multi-scale Classification using Localized Spatial Depth
Subhajit Dutta, Anil K. Ghosh
In this article, we develop and investigate a new classifier based on features extracted using spatial depth. Our construction is based on fitting a generalized additive model to t…
