Problems solved by technology

[0003] The establishment of a digital twin city involves a huge amount of data. These data are very complex, not only in terms of the amount of data, but also in the multi-dimensionality of the data. The overall understanding of these data has far exceeded the ability of humans. High-dimensional data cannot be effectively predicted

Description

technical field [0001] The embodiments of the present invention relate to the technical field of neural networks, and in particular to a digital city prediction method, device, equipment and storage medium. Background technique [0002] In the process of establishing a digital twin city, it is generally necessary to collect data of real objects in real life through the Internet of Things or sensory network devices to form a simulation model. In the field of digital twins of smart cities, the data of twin targets are usually multi-dimensional data. For example, the building model: it includes the geographical information of the building, natural information, user information in the building, energy consumption information, etc. These different dimensions together constitute the multidimensional data model of the building. At the same time, when urban managers use digital twin cities for urban management, they must obtain prediction results after adding the influence of superv...
