Background
In recent years, data mining has attracted great attention in the information industry, mainly because of the large amount of data generated in the real world, the wide spread use of the data, and the urgent need to convert the data into useful information and knowledge. The information and knowledge obtained can be used in a wide variety of applications including business management, production control, market analysis, engineering and scientific exploration, among others. In today's data analysis scenario, the following two key issues are still faced:
on one hand, with the continuous development of social environment, data has more and more complexity and diversity, and especially data sources and data information types have diversity as well. For example, in a city perception environment, different environmental information such as temperature, humidity, illumination and the like can be collected in the same area; meanwhile, different data providers (data sources) can simultaneously acquire different types of data information due to the range of activities and the diversity of devices used. In order to reduce the deviation caused by using a single type of data in the data analysis process, a data analyzer needs to select diversified representative data information (for example, balance the selection quantity of different types of data information).
On the other hand, the data fusion can adopt a fusion method for multi-source data so as to further improve the accuracy of data analysis. Information fusion is a multi-level and multi-aspect process that detects, combines, correlates, estimates, and combines multi-source data to achieve accurate state estimation. After the preferred multi-source data is obtained, a data fusion method capable of fully utilizing the characteristics of the multi-source data is urgently required.
