Loan Default Classifier
Binary classifier predicting whether a loan applicant will default, mirrored here from the
MLflow Model Registry of the source project (loan-default-classifier, best model: xgboost).

Usage
model.pkl is a scikit-learn Pipeline (preprocessing + classifier) saved with joblib. It expects
a single-row DataFrame with these raw feature columns:
Age, Income, LoanAmount, CreditScore, MonthsEmployed, NumCreditLines, InterestRate, LoanTerm, DTIRatio, Education, EmploymentType, MaritalStatus, HasMortgage, HasDependents, LoanPurpose, HasCoSigner
import joblib
import pandas as pd
pipeline = joblib.load("model.pkl")
row = pd.DataFrame([{...}], columns=['Age', 'Income', 'LoanAmount', 'CreditScore', 'MonthsEmployed', 'NumCreditLines', 'InterestRate', 'LoanTerm', 'DTIRatio', 'Education', 'EmploymentType', 'MaritalStatus', 'HasMortgage', 'HasDependents', 'LoanPurpose', 'HasCoSigner'])
probability = pipeline.predict_proba(row)[0, 1]
Trained as part of an end-to-end MLOps pipeline (DVC + MLflow + FastAPI + Docker + GitHub Actions). Source repository: https://github.com/Yashwanth-R19/loan-default-mlops
