💰 Loan Prediction System

🔍 A Smart Loan Approval AI Tool Predict Loan Approval using Machine Learning , with REST API

---

📌 Overview

This project predicts Loan Approval with trained machine learning models such as (Logistic Regression , Ridge Classification, XGBOOST and Random forest Classifier )built on credit and income features. Additionally, it generates custom financial advice using a LLM, customized Report based on the outcome.

🔧 Stack:
FastAPI (backend) + SQLite3 (database) + React + Tailwind + TypeScript (frontend) + MLflow (tracking) + **LLM ** for insights.

📦 Step 1: Environment Setup

✅ Python Version: 3.8 - 3.10 (Recommended < 3.11)

git clone https://github.com/Ajitkumar-1001/Loan_prediction_App.git
cd Loan_prediction_App
python -m venv Loan_App
source Loan_App/bin/activate
pip install -r requirements.txt

---

2️⃣ Database Setup

Create a SQLite database and required tables from the CSV dataset.

python create_database.py

3️⃣ Model Training + Logging

Train the model with feature selection, PCA, and classifiers like Logistic Regression, Random Forest, and Ridge. Log metrics using MLflow.

python train_model.py

🧠 FastAPI Backend

🔧 Start the server:

uvicorn loan_api.main:app --reload

🔁 Endpoints:

• POST /Loan/predict-loan → returns prediction + LLM-based suggestion

---

💻 React Frontend

📁 Navigate to frontend:

cd frontend
npm install

🚀 Start development server:

npm run dev

• Form input fields
• Animated prediction + suggestions
• Validation to avoid empty or negative values

📬 API Example

POST /Loan/predict-loan
{
  "IncomePerDependent": 10000,
  "LoanAmount": 2500000,
  "RiskScore": 650,
  "TotalDebtToIncomeRatio": 0.4,
  "InterestRate": 7.5,
