Welcome to the Machine Learning Domain

Welcome to the CDI Machine Learning Q&A Guide — a hands-on domain focused entirely on machine learning, built for learners who want to go beyond theory.

This guide teaches machine learning through real-world questions, using both Python and R as practical tools. You’ll work through clean, reproducible examples grounded in professional data workflows.

💡 In many Q&As, you’ll see both Python and R solutions. When necessary, we treat each language separately to ensure clarity — especially for longer or advanced workflows.

You’ll explore: - 🔍 How to prepare data for modeling
- 🧠 How to train models like decision trees, SVMs, and random forests
- 📈 How to evaluate model performance with real metrics
- ⚙️ How to tune hyperparameters and interpret results

Whether you’re a beginner or preparing for a data science job interview, this guide helps you build fluency in modeling with the tools that matter most in today’s job market.
