Abstract: In embodiments, an electronic device, a cabinet, or a server includes a plurality of power sources, a connection module, and a housing, where each power source is located inside the housing, at least two power input ports are disposed for each power source, the plurality of power sources have a target quantity of power input ports in total, and the target quantity of power input ports are of a first structure. The target quantity of first power ports are disposed on the housing, the target quantity of first power ports on the housing are of a second structure, and the first structure is different from the second structure.

Abstract: Provided is method for training communication decision model, including: training initial model according to first decision samples to adjust model parameters of initial model to obtain first trained model, first decision samples being samples of decisions already made by first communication site; acquiring at least one modification value of second model parameter of at least one second trained model, each second trained model being obtained by training initial model according to second decision samples of one second communication site, second decision samples being samples of decisions already made by the second communication site, and each modification value of second model parameter representing at least part of modifications to model parameters of second trained model relative to those of initial model; adjusting model parameters of trained model according to at least part of modification values of second model parameters to obtain communication decision model for first communication site.
