Linear Regression Is Actually a Projection Problem (Part 2: From Projections to Predictions)

1. 1Understand the vector view of least squares
2. 2Recognize how projections relate to linear regression
3. 3Apply this perspective to improve model interpretation and optimization

Data scientists and analysts can benefit from understanding this perspective, as it can improve their ability to interpret and optimize linear regression models

💡 Linear regression can be understood as a projection of data onto a lower-dimensional space

💡 Linear regression = projection problem
