WebThe Fisher information matrix (FIM), which is defined as the inverse of the parameter covariance matrix, is computed at the best fit parameter values based on local sensitivities of the model predictions to each parameter. The eigendecomposition of the FIM reveals which parameters are identifiable ( Rothenberg and Thomas, 1971 ). WebNGD methods with approximate Fisher information converge sufficiently fast in practice. Nevertheless, it remains unclear from the theoretical perspective why and under what conditions such heuristic approximations work well. In this work, we reveal that, under specific conditions, NGD with approximate Fisher information
