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. >

Early classification of network traffic through multi-classification

TL;DR: Results show that the positive impact of combination is particularly significant when there are early-classification constraints, that is, when the classification of a flow must be obtained in its early stage in order to perform network operations online.

Ensemble methods for anomaly detection and distributed intrusion detection in Mobile Ad-Hoc Networks

TL;DR: The overall results confirm the theoretical developments related with the benefits of averaging with detection accuracy improving as the authors move up in the node-cluster-manager hierarchy, and improve detection rates under very mild conditions concerning the distributions of the anomaly indexes of the normal class and the anomalous class.

Combining rough decisions for intelligent text mining using Dempster's rule

TL;DR: A boosting-like technique for generating multiple sets of rules based on rough set theory and model classification decisions from multiple set of rules as pieces of evidence which can be combined by Dempster’s rule of combination is developed.

A comparative evaluation of fusion strategies for multimodal biometric verification

TL;DR: A new strategy is proposed and discussed in order to generate a multimodal combined score by means of Support Vector Machine (SVM) classifiers from which user-independent and user-dependent fusion schemes are derived and evaluated.

Probabilistic Reasoning in Intelligent Systems: Networks of Plausible Inference

TL;DR: Probabilistic Reasoning in Intelligent Systems as mentioned in this paper is a complete and accessible account of the theoretical foundations and computational methods that underlie plausible reasoning under uncertainty, and provides a coherent explication of probability as a language for reasoning with partial belief.

A mathematical theory of evidence

Glenn Shafer
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.
