Seleksi Atribut Menggunakan Information Gain Untuk Clustering Penduduk Miskin Dengan Validity Index Xie Beni
Bibliographic record
Abstract
Di wilayah Kecamatan Bantul, seorang warga disebut sebagai keluarga miskin berdasarkan beberapa aspek seperti aspek pangan, sandang, papan, penghasilan, kesehatan, pendidikan, kekayaan, air bersih, listrik maupun jumlah jiwa. Aspek-aspek tersebut akan digunakan sebagai atribut dalam proses clustering. Masing-masing atribut memiliki nilai yang akan diolah. Penelitian ini dikerjakan menggunakan seleksi atribut information gain sebelum proses clustering untuk melihat atribut mana yang sebenarnya berpengaruh dan tidak, sehingga hanya atribut yang berpengaruh saja yang akan digunakan, metode Fuzzy C-Means untuk clustering penduduk miskin dan Xie Beni untuk menentukan jumlah klaster terbaik. Hasil penelitian menunjukkan penggunaan information gain dengan threshold 0.0001 untuk clustering dengan menghilangkan atribut penghasilan memiliki hasil cluster yang sama dengan menggunakan atribut penghasilan. Pengujian terhadap 23, 500, 1000 dan 1313 untuk jumlah cluster 2, 3, 4, 5, 6 dan 7 menunjukkan bahwa nilai dari Xie-Beni Index terkecil adalah 5 dengan nilai 0,1343, sehingga cluster yang paling optimal adalah 5.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
