300 applicant credit
dengan resiko buruk
700 applicant credit
dengan resiko minimum Secara general, rata-rata
applicant berusia antara 20
tahun hingga 40 tahun
EKSPLORASI DATA
10
Secara general, rata-rata
applicant melakukan pinjaman
kredit untuk kebutuhan
barang-barang tersier
Secara general, jumlah good
creditor pada status
kepemilikan rumah lebih
tinggi daripada bad creditor
HOLD OUT DATA

Hold out data digunakan untuk membagi data
menjadi data testing dan data training
Kemudian, untuk proses selanjutnya menggunakan
data training untuk melakukan pemodelan

0,271
SVM 0,307
XGB Classifier
0,351
Maka, digunakan XGB Classifier untuk
cross validation
CROSS VALIDATION
13
Gamma 0,1 Gamma 0,01
Nilai akurasi paling tinggi
adalah XGB Classifier dengan
gamma 0,01
RESULT
14
Dari keempat metode klasifikasi yang
dilakukan, maka metode klasifikasi yang
paling baik digunakan untuk menganalisis
German Credit Data adalah XGBClassifier
menggunakan gamma 0,01 dengan akurasi
sebesar 72,8% dan presisi sebesar 72,4%
