Problems solved by technology

[0002] In the era of big data, the emergence of massive data enables people to obtain unprecedented large-scale samples when dealing with computing problems, but at the same time they have to face more complex data objects
In the real world, the original data is obtained from various actual application systems. Since the data of each actual application system lacks a unified standard definition, and the data structure is also quite different, there is a large inconsistency in the data between the systems. , often cannot be used directly
At the same time, due to defects in the design of the actual application system and some human factors in the use process, some data attribute values ​​may be lost or uncertain in the data records, and necessary data may be missing, resulting in incomplete data. Data mining cannot be performed directly, or the mining results are unsatisfactory
