In this paper, first, an initial feature vector for vocal fold pathology diagnosis is proposed. Then, for optimizing the initial feature vector, a genetic algorithm is proposed. Some experiments are carried out for evaluating and comparing the classification accuracies which are obtained by the use of the different classifiers (ensemble of decision tree, discriminant analysis and K-nearest neig...

In today world of internet, it is important to feedback the users based on what they demand. Moreover, one of the important tasks in data mining is classification. Today, there are several classification techniques in order to solve the classification problems like Genetic Algorithm, Decision Tree, Bayesian and others. In this article, it is attempted to classify researchers to “Expert” and “No...

The use of demands such as "Iranian-Islamic architecture" or "preservation of Iranian-Islamic identities" appeared in different dimensions and have gradually caused the shape of contemporary Iranian architecture. Many criticisms have been made from various perspectives on the architectural conditions, despite, all of them are worthy of attention, it seems that a required issue has been neglecte...

Web classification has been attempted through many different technologies. In this study we concentrate on the comparison of Neural Networks (NN), Naïve Bayes (NB) and Decision Tree (DT) classifiers for the automatic analysis and classification of attribute data from training course web pages. We introduce an enhanced NB classifier and run the same data sample through the DT and NN classifiers ...

We estimate the effect that six types of high school math courses have on students’ earnings nearly a decade after graduation. We use High School and Beyond transcript data to differentiate courses at a more detailed level than in previous research. This enables us to show that more-advanced courses have larger effects than less-advanced ones. We also provide evidence that math courses can help...

The higher education system plays a critical role in supporting the transition towards circular economy (CE). It helps create business leaders and policymakers having appropriate skills, competences, consciousness referring to CE challenges. Nevertheless, few studies have specifically investigated how is addressing CE, current academic offering integrating principles, which skills competences a...

difference aspects of multinomial statistical modelings and its classifications has been studied so far. in these type of problems y is the qualitative random variable with t possible states which are considered as classifications. the goal is prediction of y based on a random vector x ? ir^m. many methods for analyzing these problems were considered. one of the modern and general method of cla...
