The paper deals with the estimation of the differential entropy of the probability density function of a stochastic system. A nonparametric entropy estimator based on particles with weights is proposed. The estimator provides asymptotically unbiased estimates. For small number of particles, the bias originates from the difference between the state density and the sampling density. A simulation study is provided. The approach to the differential entropy estimation by particles is a pillar of the fusion problem.
