In this paper, Variational Mode Decomposition (VMD) and Stacking model fusion are composed to obtain a short-term load forecasting method for real-time power dispatch. Firstly, a VMD algorithm decomposes the load series into dissimilar intrinsic mode functions (IMF), and the Approximate Entropy (...

model.And we build a ship navigation state prediction model based on Stacking model fusion, introduce the selection and experiment process of classifier in the double layer model,and optimize the model parameters. 3.We compare the Stacking model with the learning curve of the 3 base classifier, ...
For them, this paper provided an ethical decision-making model based on stacking fusion mechanism, in which machine learning and deep learning were deeply integrated. Firstly, naive Bayes model based on attribute correlation (ACNB), weighted average first-order Bayes model (WAD...
