WebThe Fisher is a nonlinear function of the weights and data. To compute its spectrum, we extend the framework developed by Pennington and Worah [13] to study random matrices with nonlinear dependencies. As we describe in Section 2.4, the Fisher also has an internal block structure that complicates the resulting combinatorial analysis.
WebNov 21, 2024 · The Fisher information is the variance of the score, I N (θ) = E[(∂ θ∂ logf θ(X))2] =⋆ V[logf θ(X)].
