One-Sided Prototype Selection on Class Imbalanced Dissimilarity Matrices
(Springer Berlin Heidelberg, 2012)
In the dissimilarity representation paradigm, several prototype selection methods have been used to cope with the topic of how to select a small representation set for generating a low-dimensional dissimilarity space. In ...
Improving Risk Predictions by Preprocessing Imbalanced Credit Data
(Springer Berlin Heidelberg, 2012)
Imbalanced credit data sets refer to databases in which the class of defaulters is heavily under-represented in comparison to the class of non-defaulters. This is a very common situation in real-life credit scoring ...
Gender Classification from Pose-Based GEIs
(Springer Berlin Heidelberg, 2012)
This paper introduces a new approach for gait-based gender classification in which some key biomechanical poses of a gait pattern are represented by partial Gait Energy Images (GEIs). These pose-based GEIs can more accurately ...
Assessment of Financial Risk Prediction Models with Multi-criteria Decision Making Methods
(Springer Berlin Heidelberg, 2012)
A wide range of classification models have been explored for financial risk prediction, but conclusions on which technique behaves better may vary when different performance evaluation measures are employed. Accordingly, ...
