Abstract: Provided are a method for determining representation information performed by a computer device. The method includes: obtaining a heterogeneous graph of a target resource service; performing graph convolution on the heterogeneous graph through a graph neural network based on a plurality of types of meta-paths of a plurality of nodes in the heterogeneous graph, to obtain initial representation information of a first-class object node and initial representation information of a second-class object node; and fusing the initial representation information of the first-class object node and the initial representation information of the second-class object node based on an edge connecting different nodes in the heterogeneous graph, to obtain target representation information of the first-class object node.

Abstract: The present disclosure provides a multifunctional fuse. The multifunctional fuse includes a fuse element, a pre-charging resistor, and an inner housing. The inner housing is provided with a receiving cavity, the fuse element is received in the receiving cavity, and the pre-charging resistor is wound around an outer side of the inner housing and is in contact with the inner housing. The multifunctional fuse of the present disclosure resolves problems of large volumes and high costs of a pre-charging resistor and a fuse in a high voltage circuit in the related art.
