Abstract

One of artificial intelligence methods, which is artificial neural networks, have been widely used in data analysis to make predictions, forecasting, and data classification. The artificial neural network method has convergence or local minimum problems because it requires randomly generated weight values. There is a lot of research that discusses optimization techniques for initiating this initial weight to solve that problem. In this study, a meta-analysis was carried out regarding the implementation of genetic algorithms for optimization of artificial neural network methods. Based on 10 journals that has reviewed in this study, it was concluded that optimization of the genetic algorithm can increase the output value of the artificial neural network by 3.44%, but this genetic algorithm optimization have no significant effect based on the sig (2-tailed) value is 0.595 and t count value is 0.551 that have been obtained and tested using paired samples t-test method with help of SPSS software.

Abstract

Early detection of diabetes mellitus is crucial to prevent severe complications. This study evaluates three machine learning algorithms for diabetes prediction using a quantitative comparative experimental design. The algorithms are k-Nearest Neighbors (k-NN), Support Vector Machine (SVM), and Random Forest. These methods were chosen to compare distinct learning paradigms. k-NN is distance-based, SVM is margin-based, and Random Forest is an ensemble method. The goal is to find the optimal model for clinical use. The Pima Indians Diabetes dataset was used. It includes 390 patients and 15 clinical features. Performance was measured by accuracy, precision, recall, and F1-score. Random Forest had the highest accuracy (89.7%) and F1-score, providing the most balanced classification. SVM followed with 84.6%, and k-NN achieved 76.9%. Although k-NN had the highest recall (0.750), its precision was low (0.375), showing a high false-positive rate. Feature importance analysis pointed to blood glucose levels as the most significant predictor, which matches clinical knowledge. In summary, ensemble techniques like Random Forest offer the most reliable results. This highlights the importance of selecting the right algorithm for early diabetes detection in clinical applications.

Abstract

The speed with which emerging digital technologies have changed our communications has impacted many aspects of the communication process wherever people interact in their personal and professional lives. In part this study sought to explore the influence of emerging digital communication technologies on users’ communication behaviors, perceptions and attitudes. A quantitative research design was used. Data was collected online through an online survey. We collected data from 278 participants age 18 years and older. Stratified random sampling was used to provide an adequate demographic representation. The instrument consisted of demographic items, technology use patterns and Likert-style questions to depict users’ perception of if their communication changed and about their attitude toward technology.  Descriptive statistics indicated very high use rates of e-mail (89.3%), AI (86.5%) and video conferencing (84.0%). While technology use varied daily, 27.3% of participants indicated they spent more than five hours each day communicating digitally. When user perceptions associated with technology impacts were reported as moderate agreements that the emerging technologies improved the speed and access of communication; however, concussions about the quality of the interaction that replaced face-to-face time was are something to think about. We'd like to point out that the overall reliability of the survey instrument was reasonable69 for a couple of key sections, Cronbach's alpha was above 0.7. The initial findings of this research indicate that while emerging digital technologies have improved the speed of connection and efficiency in communication, users are still careful of the social ramifications. Future discussions and strategies should look to balance technological gains and the need for some form of inter-personal relationship. This research is a contribution to the literature for research and practice, especially as it relates to the burgeoning evolution of digital communications.
