Focal Concept

The typicality of a concept instance is related to the frequency with which its constituent features occur among all instances of the focal concept and possibly of other contrasting concepts. According to a simple frequency model, the prototype consists of the features that have occurred most often among instances of the focal concept. But according to a validity model, the prototype has the features that have occurred frequently among focal instances and, at the same time, infrequently among instances of contrast categories. By this account, the extent to which features overlap among focal and contrast instances is important in prototype formation. Here the feature frequencies among focal instances and the degree to which these features overlapped with contrast instances were manipulated. Twenty undergraduate college students first studied instances of the contrast category and then instances of the focal category. Next, they provided typicality ratings, frequency estimates of whole stimuli, and frequency estimates of features. All three measures supported the prediction of a simple frequency model of prototype formation.

Self Administered Questionnaire

This study aimed to determine the entrepreneurial engagement of Agri-Business graduates from Southern Philippines Agri-Business and Marine and Aquatic School of Technology (SPAMAST), during the SY 2008-2013. The data was collected using a self-administered questionnaire, analyzed and subjected to the measures of central tendency (mean and percentage) and the Statistical Package for Social Sciences (SPSS 19.0).Results showed that graduates were within 26 to 30 years old age, female, single, most were regular workers in a private company with 1 - 3 years working experience and were practicing entrepreneurs earning a monthly income of 10,000. High rating was extended to the level of competence on attitudinal, behavioral and educational factors. It was found out that, the respondents either felt, thought and view entrepreneurship as a thing that they had dreamed to undertake after graduation because they believed that it is only doing entrepreneurial undertakings that they can fulfill the objectives of the course and their personal beliefs that success can be attained through it.Further, only few graduates had started their entrepreneurial engagement, while the majority, were still thinking about their entrepreneurial endeavor because of the difficulty in starting own business due to the complex administrative procedures involved. The demographic and socio-economic profile had no significant influence to the level of engagement while the level of competencies significantly influenced the level of entrepreneurial engagement.

This paper proposes the use of a goal programming model for the objective ranking of universities. This methodology has been successfully used in other areas to analyze the performance of firms by focusing on two opposite approaches: (a) one favouring those performance variables that are aligned with the central tendency of the majority of the variables used in the measurement of the performance, and (b) an alternative one that favours those different, singular, or independent performance variables. Our results are compared with the ranking proposed by two popular World University Rankings, and some insightful differences are outlined. We show how some top-performing universities occupy the best positions regardless of the approach followed by the goal programming model, hence confirming their leadership. In addition, our proposal allows for an objective quantification of the importance of each variable in the performance of universities, which could be of great interest to decision-makers.

AbstractObjectivesThis research work exclusively aims to develop a novel heart disease prediction framework including three major phases, namely proposed feature extraction, dimensionality reduction, and proposed ensemble-based classification.MethodsAs the novelty, the training of NN is carried out by a new enhanced optimization algorithm referred to as Sea Lion with Canberra Distance (S-CDF) via tuning the optimal weights. The improved S-CDF algorithm is the extended version of the existing “Sea Lion Optimization (SLnO)”. Initially, the statistical and higher-order statistical features are extracted including central tendency, degree of dispersion, and qualitative variation, respectively. However, in this scenario, the “curse of dimensionality” seems to be the greatest issue, such that there is a necessity of dimensionality reduction in the extracted features. Hence, the principal component analysis (PCA)-based feature reduction approach is deployed here. Finally, the dimensional concentrated features are fed as the input to the proposed ensemble technique with “Support Vector Machine (SVM), Random Forest (RF), K-Nearest Neighbor (KNN)” with optimized Neural Network (NN) as the final classifier.ResultsAn elaborative analyses as well as discussion have been provided by concerning the parameters, like evaluation metrics, year of publication, accuracy, implementation tool, and utilized datasets obtained by various techniques.ConclusionsFrom the experiment outcomes, it is proved that the accuracy of the proposed work with the proposed feature set is 5, 42.85, and 10% superior to the performance with other feature sets like central tendency + dispersion feature, central tendency qualitative variation, and dispersion qualitative variation, respectively.ResultsFinally, the comparative evaluation shows that the presented work is appropriate for heart disease prediction as it has high accuracy than the traditional works.
