Finding the Minimum

The nouns change — loss, calibration error, portfolio risk. The shape is the same — choose a number to improve, move through choices, stop when improvement runs out. This path reads the optimization module first, then walks the three applications that already use it, with the same five-step skeleton in mind on every page.

Most of math that calls itself fitting, tuning, minimizing, or finding equilibrium is one procedure under different vocabularies. Read the skeleton once; the rest of the path is the same five steps with three different what to improve.
