considers the state variables and observation variables of the full sequence. Secondly, it does not normalize each node, but global normalization of all features.Therefore, the global optimal value can be obtained. What are the disadvantages of such a good model? Due to the large processing range, the convergence of parameter estimates slows down and the iteration complexity increases.Type, so the complexity is higher. Here, several common modeling methods for dynamic models are introduced. In
