Category Theory is used to describe a category of fusors. The category is formed from a model of a process begining with an event and leading to the final labeling of the event. Although many techniques of fusing information have been developed the inherent relationships among different types of fusion techniques (fusors) have not yet been fully explored. In this paper, a foundation of fusion i...

A novel method is described for obtaining superior classiication performance over a variable range of classiication costs. By analysis of a set of existing classiiers using a receiver operating characteristic (ROC) curve, a set of new realisable classiiers may be obtained by a principled random combination of two of the existing classiiers. These classiiers lie on the convex hull that contains ...

The area under the receiver operating characteristic (ROC) curve, known as the AUC, is currently considered to be the standard method to assess the accuracy of predictive distribution models. It avoids the supposed subjectivity in the threshold selection process, when continuous probability derived scores are converted to a binary presence–absence variable, by summarizing overall model performa...

• This work overviews some developments on the estimation of the Receiver Operating Characteristic (ROC) curve. Estimation methods in this area are constantly being developed, adjusted and extended, and it is thus impossible to cover all topics and areas of application in a single paper. Here, we focus on some frequentist and Bayesian methods which have been mostly employed in the medical setti...

In recent years hazard models, using both market and accounting information, have become state of the art in predicting firm bankruptcies. However, a comprehensive test comparing their performance against the traditional accounting-based approach or the contingent claims approach is missing in the literature. Using a complete database of UK Main listed firms between 1979 and 2009, our Receiver ...

Winning a One Day International (ODI) cricket match depends on various factors related to scoring as well as the athletic strengths of the two teams. While some of these factors have been well analyzed in the literature, others have yet to be investigated. In this analysis, statistical significance for a range of variables that could explain the outcome of an ODI cricket match is explored. In p...

Adaptive beamforming is capable of separating user signals transmitted on the same carrier frequency, and thus provides a practical means of supporting multiusers in a space-division multipleaccess scenario. Moreover, for the sake of further improving the achievable bandwidth efficiency, highthroughput quadrature amplitude modulation (QAM) schemes have becomes popular in numerous wireless netwo...

These days, the demand for mobile transmission bandwith seems to be a never ending story. To get insights into the real world, wireless transmission measurements and not only simulations of mobile communication systems are necessary. For this task, the Vienna Wireless Testbed has been developed. To keep pace with future developments, the testbed has to be extended and updated constantly. Furthe...

Othogonal Frequency Division Multiplex (OFDM) has gained considerable attention in recent years. It has been adopted for various standards include the 802.11a wireless LAN standard. In this project, we implemented an OFDM receiver based 802.11a standard. Furthermore, since spatial diversity is the ultimate way to increase system capacity in bandwidth-cautious wireless applications, the SVD ante...
