The difference of the K-Nearest Neighbors approach
Breiman, L. (2001). Statistical modeling: The two cultures (with comments and a rejoinder by the author). Statistical Science, 16(3), 199-231.
In Statistical Learning:
→ Data modelling
y(𝒳1, 𝒳2,....𝒳n) = ꞵ0 + ∑ ꞵi𝒳i + ε
- e.g., Multiple regression, Discriminant Analysis, etc.,

- A set of algorithmic instructions that relate the independent and dependent variables.
- e.g., K-Nearest Neighbors , Random forests, etc.,
