Comparison of Support Vector Machines and Multilayer Perceptrons in the Classification Process: A Case Study of Heart Disease Analysis
No full textPattern Recognition is an important area in computer science that maps data to predefined concepts. Support Vector Machines (SVM) are particularly effective due to their ability to identify the optimal hyperplane that separates two classes in the feature space. Unlike neural networks, which look for a separating hyperplane, SVM determines the best hyperplane in the input space. SVM primarily serves as a linear classifier but can also address non-linear problems through the kernel trick, enabling high-dimensional operations. This paper delves into the foundational principles of SVM and its applications, specifically in classifying heart disease symptoms in individuals. The research includes the implementation of Gaussian Radial Basis Function (RBF) and Polynomial (POLY) kernel functions, along with various parameters affecting SVM performance. Additionally, a comparative analysis with Multilayer Perceptron (MLP) for data classification is presented to evaluate the effectiveness of the proposed kernel functions

Analisis kemandirian belajar matematika siswa smp pada masa transisi pembelajaran daring ke luring
No full textAbstract
This study aims to analyze the level of mathematics learning independence of seventh grade students of SMPN 1 Samarang after the transition from online to offline learning. A descriptive qualitative approach was used with the subjects of three students selected through purposive sampling technique. Data were collected through open-ended questionnaires, in-depth interviews, and field notes, then analyzed by triangulation to test the validity of the data based on eight indicators of learning independence: (1) learning initiative, (2) diagnosing learning needs, (3) setting learning goals, (4) viewing difficulties as challenges, (5) finding relevant sources, (6) determining learning strategies, (7) evaluating learning outcomes, and (8) self-confidence. The results showed variations in the achievement of learning independence indicators for each student. S-1 students met 6 out of 8 indicators (75%), with weaknesses in learning initiatives and utilization of learning resources. S-2 met 5 indicators (62.5%), especially in setting strategies and evaluating learning outcomes, but lacked in setting goals and finding sources. S-3 only fulfilled 3 indicators (37.5%), with limitations in initiative, diagnosis of needs, and self-confidence. Overall, the indicators “setting learning strategies” and “evaluating learning outcomes” achieved the highest percentage (100%), while “setting learning goals” was the lowest (24%). The findings confirm that the post-pandemic learning transition has an impact on learning independence, where students tend to still depend on teachers and friends (peer-dependent) and underutilize independent learning resources. The pedagogical implications of this study emphasize the need for self-directed learning training and enrichment of digital learning resources to improve students\u27 independence. The limitations of the study lie in the small number of subjects and the specific context of the school. Further research is recommended to test technology-based intervention models to facilitate post-pandemic learning independence.

Penelitian ini bertujuan untuk menganalisis tingkat kemandirian belajar matematika siswa kelas VII SMPN 1 Samarang pasca transisi pembelajaran daring ke luring. Pendekatan kualitatif deskriptif digunakan dengan subjek tiga siswa yang dipilih melalui teknik purposive sampling. Data dikumpulkan melalui angket terbuka, wawancara mendalam, dan catatan lapangan, kemudian dianalisis dengan triangulasi untuk menguji keabsahan data berdasarkan delapan indikator kemandirian belajar: (1) inisiatif belajar, (2) mendiagnosis kebutuhan belajar, (3) menetapkan tujuan belajar, (4) memandang kesulitan sebagai tantangan, (5) mencari sumber relevan, (6) menetapkan strategi belajar, (7) mengevaluasi hasil belajar, dan (8) kepercayaan diri. Hasil penelitian menunjukkan variasi capaian indikator kemandirian belajar pada masing-masing siswa. Siswa S-1 memenuhi 6 dari 8 indikator (75%), dengan kelemahan pada inisiatif belajar dan pemanfaatan sumber belajar. S-2 memenuhi 5 indikator (62,5%), terutama dalam menetapkan strategi dan evaluasi hasil belajar, tetapi kurang dalam menetapkan tujuan dan mencari sumber. S-3 hanya memenuhi 3 indikator (37,5%), dengan keterbatasan pada inisiatif, diagnosis kebutuhan, dan kepercayaan diri. Secara keseluruhan, indikator "menetapkan strategi belajar" dan "mengevaluasi hasil belajar" mencapai persentase tertinggi (100%), sementara "menetapkan tujuan belajar" paling rendah (24%). Temuan ini mengonfirmasi bahwa transisi pembelajaran pasca-pandemi berdampak pada kemandirian belajar, di mana siswa cenderung masih bergantung pada guru dan teman (peer-dependent) serta kurang memanfaatkan sumber belajar mandiri. Implikasi pedagogis dari penelitian ini menekankan perlunya pelatihan self-directed learning dan pengayaan sumber belajar digital untuk meningkatkan kemandirian siswa. Keterbatasan penelitian terletak pada jumlah subjek yang kecil dan konteks spesifik sekolah. Penelitian lanjutan disarankan untuk menguji model intervensi berbasis teknologi guna memfasilitasi kemandirian belajar pasca-pandemi
