🚀 K-Nearest Neighbors (KNN) Explained for Beginners | Intuition, Distances, K Value & Curse of Dimensionality
In this video, you’ll learn the complete theoretical foundation of the K-Nearest Neighbors (KNN) algorithm, one of the most popular and easiest Machine Learning algorithms used for classification and prediction tasks.
📌 What you’ll learn in this video:
✅ What is KNN and how it works
✅ Real-world intuition behind KNN
✅ Step-by-step KNN workflow
✅ How KNN identifies the nearest neighbors
✅ Euclidean Distance explained with examples
✅ Manhattan Distance explained with examples
✅ How to choose the right value of K
✅ Underfitting vs Overfitting in KNN
✅ Curse of Dimensionality and why it affects KNN performance
✅ Advantages and limitations of KNN
This video focuses on building a strong conceptual understanding before we start coding.
🎯 Next Video:
We’ll implement KNN end-to-end using Python and Scikit-Learn, including:
Loading a dataset
