Webb11 mars 2024 · The score for a multiple parameter problem (a vector parameter) is itself a vector. We need to take partial derivatives of the log likelihood with respect to each model parameter. Let's consider an example. Find the score vector for X1, X2, …, Xn ∼ N(μ, σ2) where the Xi are iid N(μ, σ2) samples. WebbThis score function is critical in that it actually decides what prediction sets we could get. For instance, in regression problems, we could take the ŷ-y as the score function. This way, the resulting prediction sets whose values are within an L1-norm ball around the prediction ŷ; in classification problems, we could take 1-ŷ_i as the score function, where …
