Beginner-friendly AutoML library for tabular data

Project description

KrishnAutoML 🚀

PyPI version Build Status License

KrishnAutoML is a lightweight, beginner-friendly, and production-ready AutoML library for tabular data.
It automates the end-to-end machine learning workflow with minimal user input, while keeping things modular and extensible.


✨ Features

  • 📂 Load data from CSV or Pandas DataFrame
  • 🔍 Automatic problem type detection (classification or regression)
  • 🧹 Smart preprocessing (missing values, categorical encoding, scaling)
  • 📊 Optional EDA reports for insights
  • 🤖 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")
