Claim 2:
3. The predictive contrastive representation method according to claim 1, wherein the step of mapping the temporal coding information at the current moment and the future situational information by using the logarithmic bilinear model to obtain the similarity between the temporal coding information at the current moment and the future situational information comprises:
mapping the temporal coding information at the current moment and the future situational information by using the logarithmic bilinear model to obtain the following similarity between the temporal coding information at the current moment and the future situational information:

ƒk(st+k,ct)=exp(zt+kKWkct)

wherein ct denotes the temporal coding information at the current moment t, st+k denotes the future situational information, zt+kK denotes coding information of the future situational information, K denotes a number of moments, W denotes a weight coefficient matrix, and k denotes a serial number of a moment.
