Uncertainty evaluation for unknown distribution data is a key problem to be solved in uncertainty theory. To evaluate the measurement of with distributions, novel method based on particle filter (PF) and beta proposed this paper. A wide adaptability was adopted as type results, parameters were taken estimated, state-space model established. The PF method, suitable non-Gaussian data, utilized obtain estimates according results. Finally, best results their calculated using parameters....

In order to evaluate the measurement uncertainty of data with unknown distributions, a novel evaluation method based on particle filter (PF) and beta distribution was proposed in this paper. After establishing dynamic constant mean state space model, distributions were employed describe prior, noise posterior parameters be evaluated. The particles evaluated obtained by PF recursion, then best estimates measured their uncertainties can calculated. Simulation results show that is adaptive...
