Computing the polytomous discrimination index
Statistics in Medicine, 2021Polytomous regression models generalize logistic models for the case of a categorical outcome variable with more than two distinct categories. These models are currently used in clinical research, and it is essential to measure their abilities to distinguish between the categories of the outcome.

Feature Selection Based on Neighborhood Discrimination Index
IEEE Transactions on Neural Networks and Learning Systems, 2017Feature selection is viewed as an important preprocessing step for pattern recognition, machine learning, and data mining. Neighborhood is one of the most important concepts in classification learning and can be used to distinguish samples with different decisions.

Nonparametric estimation and inference for polytomous discrimination index
Statistical Methods in Medical Research, 2017Polytomous discrimination index is a novel and important diagnostic accuracy measure for multi-category classification. After reconstructing its probabilistic definition, we propose a nonparametric approach to the estimation of polytomous discrimination index based on an empirical sample of biomarker values. In this paper, we provide the finite-sample

The development of a colour discrimination index
Lighting Research & Technology, 2017One aspect of colour rendering is to discern the difference between colours and colour discrimination. This is important for applications such as surgical procedures and industrial inspection. Two psychophysical experiments were conducted using computer generated images and real materials, including stone, wood and organs.

Extension of a Highly Discriminating Topological Index
Journal of Chemical Information and Modeling, 2015A highly discriminating topological index, EAID, is generated in our laboratory. A systematic search for degeneracy was performed on a total of over 14 million structures, and no duplicate occurred. These structures are as follows: over 3.8 million alkane trees with 1-22 carbon atoms; over 0.38 million structures containing heteroatoms; over 4 million ...

The area of the gamut, in a uniform chromaticity-scale diagram of the chromaticities of a standard array of object colors, is taken to be a measure of color-discrimination capability of an illuminant. The 1960 CIE u, v chromaticity diagram, and the eight test colors of the interim method for computing a color-rendering index, are used for demonstration.
