Comparing the Prediction of Numeric Patterns on Form C1 Using the K-Nearest Neighbors (K-NN) Method and a Combination of K-Nearest Neighbors (K-NN) with Connected Component Labeling (CCL)
Get PDFIndonesia's elections serve as a cornerstone of its democratic system, with the active participation of its citizens being of paramount importance. To bolster transparency and civic engagement during these elections, the SITUNG system (Election Result Information System) is employed for the tabulation of election results. However, the current tabulation process remains manual, potentially leading to data entry errors and a reduced accuracy of election outcomes. This research endeavor seeks to enhance the efficiency and accuracy of election result tabulation by employing the K-Nearest Neighbors (K-NN) method for recognizing numeric patterns on Form C1, both independently and in combination with Connected Component Labeling (CCL). The K-NN method demonstrates a commendable 60.0% accuracy in recognizing numeric patterns from the original Form C1 data. However, when combined with CCL, the accuracy drops to 51.2%. This research makes a significant contribution by simplifying the tabulation process and improving the accuracy of election results in Indonesia through the application of the K-NN method. The technology is anticipated to fortify democracy by promoting a more transparent and participatory electoral process for the citizens
Machine Learning Approach for Classification of Sickle Cell Anemia in Teenagers Based on Bayesian Network
Get PDFIn this study, we employed a Bayesian network approach for the classification of sickle cell anemia in teenagers based on their medical data. Sickle cell anemia is a hereditary blood disorder characterized by the presence of abnormal hemoglobin, leading to distorted red blood cells. Early detection and classification of this condition are crucial for timely intervention and improved patient outcomes. Our research focused on leveraging the algorithmic power of Bayesian network to model and analyze a diverse set of medical parameters in teenagers, including age, platelet count, mean corpuscular hemoglobin concentration (MCHC), red blood cell count, packed cell volume etc. The Bayesian network method employed for the classification of sickle cell anemia involves using a probabilistic graphical model to represent the relationships among different medical parameters. The model incorporates Bayesian principles to update and refine its predictions as new information is introduced. The method identifies key features in the dataset that contribute significantly to the classification, providing valuable insights for early detection and intervention.
