The effective prediction of bus load can provide an important basis for power system dispatching and planning energy consumption to promote environmental sustainable development. A forecasting method based on variational modal decomposition (VMD) bidirectional long short-term memory (Bi-LSTM) network was proposed in this article. Firstly, the series decomposed into a group relatively stable sub...

Factor analysis is a basic tool in statistics and machine learning, where the goal is to take many variables and explain them away using fewer unobserved variables, called factors. It was introduced in a pioneering study by psychologist Charles Spearman, who used it to test his theory that there are fundamentally two types of intelligence – verbal and mathematical.
