Hey guys, welcome back to RR Consultancy Services Ltd.

Confused between Label Encoding and One-Hot Encoding? In this video, we explain the key difference between the two most important categorical encoding techniques in Machine Learning with a practical Python implementation!

Machine Learning models only understand numbers. So what do we do when our dataset has categories like Male/Female or London/Paris? That's where Encoding comes in.

What You'll Learn in This Video:
✅ Why categorical data must be converted to numbers
✅ What is Label Encoding and how it works
✅ What is One-Hot Encoding and why it's better for nominal data
✅ The major drawback of Label Encoding (false ordinal relationship)
✅ Live Python Implementation using Pandas & Sklearn in Jupyter Notebook
✅ When to use which encoding technique

When to Use What?
Use Label Encoding when: Data is Ordinal (e.g., Low, Medium, High), Target variable encoding
Use One-Hot Encoding when: Data is Nominal (e.g., Colors, Cities, Gender), No rank between categories
