Abstract

The performance of two estimators of Fisher Information Measure (FIM) and Shannon entropy (SE), one based on the discretization of the FIM and SE formulae (discrete-based approach) and the other based on the kernel-based estimation of the probability density function (pdf) (kernel-based approach) is investigated. The two approaches are employed to estimate the FIM and SE of Gaussian processes (with different values of σ and size N), whose theoretic FIM and SE depend on the standard deviation σ. The FIM (SE) estimated by using the discrete-based approach is approximately constant with σ, but decreases (increases) with the bin number L; in particular, the discrete-based approach furnishes a rather correct estimation of FIM (SE) for L∝σ. Furthermore, for small values of σ, the larger the size N of the series, the smaller the mean relative error; while for large values of σ, the larger the size N of the series, the larger the mean relative error. The FIM (SE) estimated by using the kernel-based approach is very close to the theoretic value for any σ, and the mean relative error decreases with the increase of the length of the series. Comparing the results obtained using the discrete-based and kernel-based approaches, the estimates of FIM and SE by using the kernel-based approach are much closer to the theoretic values for any σ and any N and have to be preferred to the discrete-based estimates.
