Example Embodiment
[0060] The technical solutions in the embodiments of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention.
[0061] In order to increase the historical air quality data in the case of limited historical air quality data to improve the accuracy of air quality prediction, the model trained on the historical air quality data of cities with more air quality monitoring stations can be directly transferred to Cities with fewer air quality monitoring stations. However, this kind of migration requires that the two cities as a whole must be similar, especially the size of the city must be the same, resulting in a narrower scope of application. The present invention partitions the source city and the target city, and determines the matching area for model migration learning, so that the overall similarity of the city is not considered when the migration is performed, even if the sizes of the two cities are different, as ...
