Research on Nonlinear Correlation Tracking Technology of Financial Data Mining Based on Cloud Computing

Cloud computing is a commercial computing model that distributes computing tasks on a resource pool composed of a large number of computers, and can provide users with on-demand computing capabilities, storage capabilities, and application service capabilities; cloud computing provides storage and analysis of massive data Cheap and efficient solution. Financial data mining is a challenging research direction in the information society. The random nature of financial data makes it difficult to find the inherent rules hidden in the data. Furthermore, the properties of high-order correlation coefficients are discussed, and it is proved that high-order correlation can not only describe hidden nonlinear correlation information, but also describe the gap between linear correlation and independence. Therefore, the computational simplicity of high-order correlation can be used to track the time-varying nonlinear correlation characteristics in financial data in real time.
