By Constellate · 9 September 2026 · the short form
Overfitting is a star on the Constellate sky: placed by meaning, named, and connected to the stars around it. This is the short form of its post: the line it carries, the area we colour Computing, and what stands beside it today.
The line it carries on the sky: A model that fits the past perfectly has memorised it, not learned it.
What stands beside it
The stars nearest to it are Capabilities and Limits, The Context Window, Gradient Descent and The Map Is Not the Territory, and Capabilities and Limits, Gradient Descent and The Map Is Not the Territory are already open to walk. When Overfitting opens, the conversation will land it among them, with a line drawn to each idea it touches.
Ask for this star
Every star is lit by demand. Ask for Overfitting and it moves up the list; when it opens, this post becomes the full essay. The open stars beside it can be walked today, and the first concept of every course is free.
