A Global Indicator for Measuring the Efficiency of Machine Learning Classifier Based on Multi-Criteria Approach

Hegazy Zaher & Mohamed Abdullah · Journal of Advances in Mathematics and Computer Science · 2015

The main challenge that faces any researcher in the field of machine learning is determining the quality of an indicator used for measuring the efficiency of classifier techniques. This issue based on Multiple-Criteria Decision Making (MCDM) has not been tackled by any researcher...

Social Learning under Uncertainty Based on Dempster-Shafer Approach for Minimizing True Error of Machine Learning

Hegazy Zaher, Mohamed Abdullah & Naglaa Raga Said · Journal of Advances in Mathematics and Computer Science · 2015

Minimizing true error of the classification process under uncertainty is one of the difficult issues in the field of machine learning. Researchers do not address this topic until this time despite its importance in practical life. This paper can be considered as a development of...

An Alternative Artificial Intelligence Technique for Detecting Outliers

Hegazy Zaher, Abd El-Fattah Kandil & Rehab Shehata · Journal of Advances in Mathematics and Computer Science · 2014

Data are rarely perfect. Whether the problem is data entry errors or rare events. Outliers have two opposing properties. They can be noises that disturb regression and classification task. On the other hand, they can provide valuable information about rare phenomena, which can le...

Optimum Group Limits for Maximum Likelihood Estimation of the Exponentiated Fréchet Distribution Based on Grouped Data

A. A. Marwa, Hegazy Zaher & E. A. Elsherpieny · Current Journal of Applied Science and Technology · 2013

In many situations, instead of a complete sample, data are available only in grouped form. In this situation the values of individual observations are not known, but the number of observations that fall in each group is only known. Here the model under consideration is the expone...
