Heart Disease Prediction

A machine learning project that predicts the likelihood of heart disease based on patient data. This repository features a cleaned dataset and a Jupyter Notebook with exploratory data analysis, feature engineering, model training, and evaluation.

Notebook Overview

Inside Heart_Disease_Prediction_final.ipynb, you'll find:

• Data Exploration & Cleaning

  • Load .csv dataset with pandas.
  • Inspect features and handle missing values or outliers.

• Exploratory Data Analysis (EDA)

  • Visualize feature distributions, correlations, and target balance.

• Feature Engineering & Preprocessing

  • Encode categorical data, scale numeric features, and finalize features for modeling.

• Model Training & Evaluation

  • Train classification models (e.g., Logistic Regression, Random Forest).
  • Evaluate performance using metrics such as accuracy, precision, recall, and ROC-AUC.

• Results & Insights

  • Analyze feature importance and model strengths/weaknesses.
  • Provide visual plots (like ROC curves or feature importance bar charts).

Usage Example

1. Launch the Jupyter Notebook.

2. Execute sections in sequence:

   • Data Loading
   • EDA & Visualizations
   • Preprocessing & Feature Engineering
   • Model Training & Evaluation

3. Experiment by adjusting algorithms (e.g., try SVMs or XGBoost), tweaking hyperparameters, or adding more visual analyses.

Future Enhancements

• Model tuning with cross-validation and grid/random search.
• Deploying API endpoints for real-time heart disease prediction.
• Creating interactive dashboards using tools like Streamlit or Dash.
• Applying explainability tools such as SHAP or LIME for feature-level transparency.
