SCENARIO MODEL DYNAMIC ESTIMATION METHOD, DATA ANALYSIS METHOD AND APPARATUS, AND ELECTRONIC DEVICE

摘要

Disclosed are a scenario model dynamic estimation method and an apparatus. The method comprises: (a) establishing a scenario model for describing a dynamically changed scenario (S10); (b) acquiring sample characteristic data (S11); (c) according to the sample characteristic data, initially estimating a model parameter at an initial moment in the scenario model, and calculating the model parameter at the initial moment (S12); (d) determining the model parameter at the initial moment to be a model parameter at a current moment (S13); (e) acquiring observation characteristic data at a next moment of the current moment (S14); (f) according to the model parameter at the current moment and the observation characteristic data at the next moment, calculating a model parameter at the next moment (S15); (g) determining the next moment to be a current moment (S16); and (h) executing (e), (f) and (g) by using an iteration method until model parameters of all the moments in the scenario model are calculated (S17). This method can improve a calculation speed, so that a result is more stable and smooth.
