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. >

Combining multi-resolution evidence for georeferencing Flickr images

TL;DR: It is demonstrated experimentally that the induced belief and plausibility measures are useful to determine whether there is sufficient evidence to classify the photo at a given granularity, and an adaptive method is obtained, by which photos are georeferenced at the most appropriate resolution.

Combining multiple classifiers based on third-order dependency for handwritten numeral recognition

TL;DR: This work states that the probability distribution is optimally approximated by the third-order dependency and then multiple classifiers are combined by such third- order dependency approximation.

A mathematical theory of evidence
