Machine Learning for Business

Welcome to the Machine Learning for Business course materials repository.
This book is designed and maintained by Dr. Chandravesh Chaudhari.

The goal of this project is to bridge the gap between machine learning theory and real-world business applications, providing learners with hands-on labs, case studies, and practical deployment workflows.


Course Overview

This course takes you from mathematical foundations to state-of-the-art machine learning and AI systems with a strong focus on business decision-making.

Key features:

  • Math & Probability Foundations (quick refresher)
  • Data Wrangling & Visualization for business insights
  • Supervised & Unsupervised Learning with applied labs
  • Time Series Forecasting for inventory & sales planning
  • Neural Networks, Transformers & LLMs
  • LLM Agents & Generative AI for business use cases
  • Production ML Essentials (monitoring, drift detection, dashboards)
  • Capstone Projects & Practical Exam

    git commit -m "Added new section on XYZ"
  4. Push to your fork and open a Pull Request

I will review your contributions and merge them if aligned with the course objectives. Please ensure your submissions are clear, well-documented, and reproducible.


Running Notebooks

You have three options to run notebooks:

  1. In the Browser (No Installation Needed)

    • Click the "Launch in JupyterLite" badge in any notebook to run it instantly in your browser via JupyterLite.
  2. On Google Colab

    • Click the "Open in Colab" badge at the top of each notebook to run it in Google Colab.
  3. Locally

    • Install dependencies:
      pip install -r requirements.txt
    • Run the build and serve locally:
      chmod +x build_jupyterlite.sh
      ./build_jupyterlite.sh
