Hiking pun: ridges look L1-shaped and lassos L2-shaped
Apoorva__Lal · x · 2026-11-15
A nerdy ML joke from a hike: real-world ridges are L1-ball (diamond) shaped and lassos are L2-ball (round) shaped — the exact opposite of how Ridge (L2 penalty) and Lasso (L1 penalty) are named in regularization. The author pairs the classic L1/L2 penalty-gradient contour diagram with a lasso-rope meme, quipping about what kind of mountains Hoerl and Kennard must have been climbing.
