• 🤖 Train multiple models (LightGBM, XGBoost, CatBoost, Scikit-Learn)
• 🎯 Automated model selection and hyperparameter tuning (Optuna / GridSearchCV)
• 📈 Flexible cross-validation (KFold, StratifiedKFold, GroupKFold)
• 📝 Multiple evaluation metrics dynamically
• ⚡ Early stopping and GPU support
• 💾 Save models + reproducible pipeline code
• 📑 Auto-generated reports in HTML/Markdown

🛠 Installation

From PyPI (after publishing):

pip install krishnautoml

From source:

git clone https://github.com/<your-username>/KrishnAutoML.git
cd KrishnAutoML
pip install -e .[dev]

---

🚀 Quick Start

Python API

from krishnautoml import KrishnAutoML

# Initialize AutoML
automl = KrishnAutoML(target="Survived", problem_type="auto")

# Full pipeline
(
    automl
    .load_data("data/titanic.csv")
    .preprocess()
    .train_models()
    .evaluate()
    .save_model("best_model.pkl")
)

print("Best model metrics:", automl.best_score)

Command Line Interface (CLI)

krishnautoml fit --data data/titanic.csv --target Survived --report

This will:

• Train models
• Save best_model.pkl
• Generate an HTML performance report

📊 Example Output

Metrics (Classification example):

{'accuracy': 0.8567, 'precision': 0.8421, 'recall': 0.8312, 'f1': 0.8350}

Generated Report:

• 📈 Confusion matrix
• 🔑 Feature importance
• 📊 ROC-AUC curve
• 📑 Summary of preprocessing steps

⚙️ Advanced Usage

• 🔄 Custom cross-validation:

automl = KrishnAutoML(target="SalePrice", cv_strategy="KFold", n_splits=10)

• 🎯 Specify metrics:

automl = KrishnAutoML(target="Survived", metrics=["accuracy", "f1"])

• 📦 Load trained model:

from joblib import load
model = load("best_model.pkl")
