6. Polynomial Regression Explained | How to Model Non-Linear Data

In this video, we dive deep into the concept of **Polynomial Regression**, a powerful technique used in machine learning and data science for modeling relationships between variables that are not linear. Polynomial regression extends simple linear regression by introducing higher-degree polynomial terms, allowing us to fit curved lines to data that can't be accurately modeled by straight lines.

**What you’ll learn:**
- What polynomial regression is and how it works
- The difference between linear and polynomial regression
- How to implement polynomial regression in Python using libraries like NumPy and scikit-learn
- How to choose the degree of the polynomial for your model
- Common pitfalls and how to avoid overfitting
- Practical examples and use cases for polynomial regression

Whether you're a beginner looking to understand the basics or an experienced data scientist wanting to brush up on polynomial regression techniques, this video will provide you with the insights you need to apply this method effectively in your own projects.
