Fisher information is a well-known and well-defined concept in mathematical statistics. There are many areas in which the Fisher information is applied to, e.g., estimation theory, Bayesian statistics, frequentist statistics, optimal experimental design, computational neuroscience, physical laws, and machine learning. Therefore, the estimation of Fisher information is of critical importance. In this talk, we introduce a machine learning-based Fisher information estimation method, referred to as Fisher Information Neural Estimation (FINE). Most existing methods for Fisher information estimation rely on the estimation of the underlying distribution, which is not always possible. The proposed FINE method directly estimates the Fisher information based on the observed data. We also show via numerical examples that the proposed FINE method not only outperforms an existing method but also has a lower computational complexity.
