TLDR
On applying these methods to combine several classifiers for recognizing totally unconstrained handwritten numerals, the experimental results show that the performance of individual classifiers can be improved significantly.
Abstract
Possible solutions to the problem of combining classifiers can be divided into three categories according to the levels of information available from the various classifiers. Four approaches based on different methodologies are proposed for solving this problem. One is suitable for combining individual classifiers such as Bayesian, k-nearest-neighbor, and various distance classifiers. The other three could be used for combining any kind of individual classifiers. On applying these methods to combine several classifiers for recognizing totally unconstrained handwritten numerals, the experimental results show that the performance of individual classifiers can be improved significantly. For example, on the US zipcode database, 98.9% recognition with 0.90% substitution and 0.2% rejection can be obtained, as well as high reliability with 95% recognition, 0% substitution, and 5% rejection. >

General Combination Rules for Qualitative and Quantitative Beliefs

TL;DR: This paper proposed a combination rule for the fusion of both qualitative or quantitative beliefs, which can be used to deal directly with qualitative beliefs and to deal with the conflict between the experts' answers.

Signature verification approach using fusion of hybrid texture features

TL;DR: The proposed signature verification method was tested using four different publicly available datasets to demonstrate the generality of the proposed method and the evaluation results indicate that the proposed system outperforms other existing systems in the literature.

Subspace Classifiers in Recognition of Handwritten Digits

TL;DR: The conclusions of this thesis state that the suggested enhancements make the subspace methods very useful for tasks like the recognition of handwritten digits, which is expected to be applicable in other similar cases of recognizing two-dimensional isolated visual objects.

A mathematical theory of evidence

TL;DR: This book develops an alternative to the additive set functions and the rule of conditioning of the Bayesian theory: set functions that need only be what Choquet called "monotone of order of infinity." and Dempster's rule for combining such set functions.
