R² Score & Accuracy are not same in Machine Learning (Complete Beginner Guide)

In this video, we deeply understand the difference between Accuracy and R² Score in Machine Learning Regression problems.

Many beginners get confused between classification accuracy and regression evaluation metrics. In this tutorial, I explain:

✅ Why accuracy is not used in regression
✅ What R² Score actually means
✅ Mathematical intuition behind R² formula
✅ Error Percentage calculation
✅ Residual / Prediction Error analysis
✅ Histogram of error distribution
✅ Percentile-based error analysis (50th, 90th, 95th, 99th percentile)
✅ Business-style model evaluation
✅ Python code examples using scikit-learn, NumPy, Pandas & Matplotlib
