Descent model

Gradient descent across every layer — one probability, self-determined

01

Initialize

Weights start from layer reliability — a rough prediction, not random

02

Calculate loss

Brier vs won/lost, or the consensus of reliable layers when unlabeled

03

Calculate gradient

Slope of the error — which layers to trust more or less

04

Update weights

Step opposite the gradient. Repeat until the valley floor

Hiking the valley

Fog metaphor from the algorithm: feel the slope, take a small step opposite the gradient. Axes are neural and live-search logits; the ball is the current mix.

Self-determined mix

How much each layer may speak

Gradient descent puts weight on layers that agree and are instrumented. A blind thank-you pixel is reliability ~0.16 — the slope pushes that weight toward zero so Ads, SEO, and Analytics cannot disagree with the file.
