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. >

On combining classifiers

TL;DR: A common theoretical framework for combining classifiers which use distinct pattern representations is developed and it is shown that many existing schemes can be considered as special cases of compound classification where all the pattern representations are used jointly to make a decision.

Combining the Classification Results of Independent Classifiers Based on the Dempster/Shafer Theory of Evidence

TL;DR: A procedure is defined that transform the distance measures of different classifiers into confidence values in three subsequent steps and achieves an output vector for each distance classifier which is compatible with statistically adapted classifiers.

Complementary algorithms for the recognition of totally unconstrained handwritten numerals

TL;DR: Two novel methods for recognizing totally unconstrained handwritten numerals are presented and it is shown that if reliability is of utmost importance, one can avoid substitutions completely and still retain a fairly high recognition rate.

A combination of statistical and syntactical pattern recognition applied to classification of unconstrained handwritten numerals

TL;DR: A hierarchically structured recognition system consists of a conventional statistical classifier, a structural classifier analysing the topological composition of the patterns, a stage reducing the number of hypotheses made by the first two stages, and a mixed stage based on a search for maximum similarity between syntactically generated prototypes and patterns.
