Claim 3:
4. The predictive contrastive representation method according to claim 3, wherein the training result comprises a correct similarity between the temporal coding information at the current moment and the future situational information in the positive sample and a plurality of false similarities between the temporal coding information at the current moment and the future situational information in a plurality of negative samples; and
the step of training the similarity according to the noise contrastive estimation method and the prediction situational label data, and constructing, based on the training result, the predictive contrastive loss function for the temporal coding information at the current moment and the future situational information comprises:
training the similarity according to the noise contrastive estimation method and the prediction situational label data, and constructing, based on the correct similarity and the plurality of false similarities, the predictive contrastive loss function for the temporal coding information at the current moment and the future situational information.
