Construction method and device of continuous time dynamic graph model, equipment and storage medium

The invention discloses a construction method and device of a continuous time dynamic graph model, equipment and a storage medium, and the method comprises the steps: sampling a historical neighbor sequence, and determining a historical neighbor embedding sequence corresponding to the historical neighbor sequence through an initial continuous time dynamic graph model; determining an enhanced historical neighbor embedding sequence corresponding to the historical neighbor embedding sequence through an initial enhancement model; determining the node representation of the target node based on the enhanced historical neighbor embedding sequence through the initial continuous time dynamic graph model; the method comprises the following steps of: training an initial continuous time dynamic graph model and an initial enhancement model based on node representation, an enhanced historical neighbor embedding sequence and a historical neighbor embedding sequence; according to the method, the historical neighbor embedding
