The embodiment of the invention provides an intelligent network connection traffic data restoration method, and belongs to the technical field of data processing, and the method specifically comprises the steps: 1, extracting hidden features of traffic flow historical data through a generator, and fusing the hidden features with a to-be-restored segment, and obtaining fusion features; and step 2, inputting the fusion features into a space-time module of a generator to mine space-time relevance of the traffic flow, and obtaining a repair value corresponding to the to-be-repaired segment. According to the scheme of the invention, the to-be-restored segment and the historical segment are fused, and then the fused segment and the to-be-restored segment are subjected to weighted summation, so that the high-level semantic information hidden in the historical segment is mined, and the model parameters and the calculation time are not greatly increased while the long-term correlation characteristics of the traffic flow are captured; according to the method, multiple space-time attention and graph convolution gating circulation units are fused, the internal space-time relevance of the traffic flow is deeply mined, the repair data are obtained, and the real-time performance and the accuracy of data repair are improved.

    本公开实施例中提供了一种智能网联交通数据修复方法,属于数据处理技术领域,具体包括:步骤1,通过生成器提取交通流历史数据的隐藏特征并与待修复片段融合,得到融合特征;步骤2,将融合特征输入生成器的时空模块挖掘交通流的时空关联性,得到待修复片段对应的修复值。通过本公开的方案,将待修复片段历史片段融合,再将其与待修复片段加权求和,从而挖掘历史片段内隐藏的高级语义信息,在捕获交通流的长期时间关联特征的同时不大幅增加模型参数和计算时间,然后,融合多头时空注意力与图卷积门控循环单元,深度挖掘交通流内在的时空关联性,并得到修复数据,提高了数据修复的实时性和精准度。
