Computing the polytomous discrimination index

Statistics in Medicine, 2021
Polytomous 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, 2017
Feature 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.

Extension of a Highly Discriminating Topological Index

Journal of Chemical Information and Modeling, 2015
A 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 ...

Locality discriminating indexing for document classification

Proceedings of the 30th annual international ACM SIGIR conference on Research and development in information retrieval, 2007
This paper introduces a locality discriminating indexing (LDI) algorithm for document classification. Based on the hypothesis that samples from different classes reside in class-specific manifold structures, LDI seeks for a projection which best preserves the within-class local structures while suppresses the between-class overlap.

On Highly Discriminating Molecular Topological Index

Journal of Chemical Information and Computer Sciences, 1996
A highly discriminating molecular topological index, EAID, is proposed based on the extended adjacency matrix. A systematic search for degeneracy was performed for 3 807 434 alkane trees, 202 558 complex cyclic or polycyclic graphs, and 430 472 structures containing heteroatoms.

A time‐dependent discrimination index for survival data

Statistics in Medicine, 2005
AbstractTo derive models suitable for outcome prediction, a crucial aspect is the availability of appropriate measures of predictive accuracy, which have to be usable for a general class of models. The Harrell'sCdiscrimination index is an extension of the area under the ROC curve to the case of censored survival data, which owns a straightforward ...

Discrimination integration index as a broadband discrimination index

SPIE Proceedings, 1996
ABSTRACT Crop/weed/soil discrimination by optical reflectance on brassicas proved to be reliable for recogiwzing leaves of crops from leaves of weeds and soil, although differences on crop varieties,weed species population and type of soil. Radiometers using 10 nm bandwidth filters were used in earlier experiments, but higher reflected radiance could ...
