Abstract

Lung cancer remains a leading cause of cancer-related mortality worldwide, and Indonesia's ever-increasing amount of pollution signals an urgency for improvement in lung cancer early detection. One of the methods to detect lung cancer is molecular diagnosis using DNA microarray, which has been proven to be effective. However, the complexity of microarray data with a vast number of features hinders the timely and accurate detection of lung cancer. This study seeks to optimize the features of the data to improve classification performance. Our approach combines Mutual Information Feature Selection with Recursive Feature Elimination, leveraging the PyCaret library to train and evaluate machine learning models. The process involves initial feature reduction using Mutual Information to enhance computational efficiency, followed by training machine learning models with PyCaret. The two best-performing models for each dataset are used to perform recursive feature elimination to search for the most optimal feature. A support vector machine is also used for comparison. The final output will be three subsets of features and another subset that consists of combined features of the rest of other subsets. Finally, PyCaret will be utilized again to train machine learning models with all feature subsets. The study shows that other models can select fewer features compared to the Support Vector Machine and still maintain a powerful predictive power with high accuracy (95% - 98%). In conclusion, our research offers a new approach to selecting optimal features for microarray analysis, with implications for more effective and timely cancer diagnosis.

Abstract

Information technology (IT)-based learning models can help students obtain information quickly and accurately. This research aims to analyze the influence of IT-based learning models on junior high school students' learning outcomes. The research design used was an experiment with two groups, namely an experimental class that used an IT-based learning model and a control class that used conventional learning methods. Data was obtained through pretests and posttests given before and after treatment. The research results showed that there were significant differences between the learning outcomes of the experimental class and the control class. In the pretest, the average experimental class score was 3.37 points higher (t = 2.484; p = 0.013). This difference increased in the posttest, with the average experimental class score being 12.16 points higher (t = 4.215; p = 0.000). These findings indicate that an attractive IT-based learning model can significantly improve student learning outcomes. It is hoped that the results of this research can be a reference for educators in adopting IT-based learning models as an effective learning strategy to improve the quality of student learning outcomes.

Abstract

Background of the study: In today's digitally saturated world, individuals face cognitive overload due to the vast influx of information, including misinformation, disinformation, and malinformation. Purpose: This study investigates the relationships between perceived experiences of misinformation, disinformation, and malinformation, and their impact on information overload among Malaysian students. Method: Data were collected from 352 Malaysian students using a survey method and analyzed with Partial Least Squares Structural Equation Modeling (PLS-SEM). Participants reported their perceptions of misinformation, disinformation, malinformation experiences, and information overload on a Likert scale. Findings: Results indicate that students experience moderate levels of misinformation, disinformation, and information overload, while malinformation was less prominent. Nevertheless, significant positive relationships were found between perceived misinformation, disinformation, and malinformation experiences, and information overload, suggesting that students encountering higher levels of these information types are more likely to experience cognitive overload. Conclusion: This study underscores the challenges students face in processing vast amounts of information. It contributes to the theoretical understanding of how misinformation, disinformation, and malinformation contribute to information overload and emphasizes the need for promoting information literacy and critical thinking to mitigate these effects.
