Tournament methods in choice theory

Rational Choice Theory: An Overview

It seems easy to accept that rationality involves many features that cannot be summarized in terms of some straightforward formula, such as binary consistency.  However, this recognition does not immediately lead to alternative characterizations that might be regarded as satisfactory, even though the inadequacies of the traditional assumptions of rational behavior standard used in economic theo...

Rational Choice Theory: An Overview

It seems easy to accept that rationality involves many features that cannot be summarized in terms of some straightforward formula, such as binary consistency.  However, this recognition does not immediately lead to alternative characterizations that might be regarded as satisfactory, even though the inadequacies of the traditional assumptions of rational behavior standard used in economic theo...

Email Categorization with Tournament Methods

We propose to deploy the tournament methods to perform the task of email categorization. The multi-class categorization process is thus broken down into a set of binary classification tasks. We implement the elimination tournament and Round Robin tournament and apply them to classify emails within 15 folders. We conduct substantial experiments to compare the effectiveness and robustness of the ...

Text Classification with Tournament Methods

This paper compares the effectiveness of n-way (n > 2) classification using a probabilistic classifier to the use of multiple binary probabilistic classifiers. We describe the use of binary classifiers in both Round Robin and Elimination tournaments, and compare both tournament methods and n-way classification when determining the language of origin of speakers (both native and non-native Engli...
