What this part means

the observed score.

Its job in the formula

s is part of the quantity the equation computes from the expression on the right.

Where the article explains it

Formally, an observed score s is not a property of a model θ\theta alone.

The passage around this formula

Formally, an observed score s is not a property of a model θ\theta alone. It is closer to s=g(θ,H,T,k,P,t)+εs = g(\theta, \mathcal{H}, T, k, \mathcal{P}, t) + \varepsilon. a function of the weights θ\theta , the harness H\mathcal{H} , the sampling temperature T , the number of samples k and how they are aggregated, the prompt template P\mathcal{P} , the date t a snapshot was queried, plus…
