[0063] refer to figure 2 , figure 2 It is the first embodiment of the method for inferring cascade effect information of the present invention, the method includes the following steps:

[0064] Step S10, acquiring a time series, and dividing the time series into multiple sub-time series.

[0065] In recent years, some work proposes to monitor the influence relationship from the perspective of object behavior time series, most of which focus on the use of single-view behavior data of objects. For example, it is proposed to construct an impact cascade diagram by polynomial fitting of behavioral time series; it is proposed to monitor the impact relationship of dynamic changes based on behavioral sequence data. However, the influence relationship between financial objects (such as currency, foreign exchange, stock, etc.) is changing rapidly. For example, after the economic crisis in 2008, the financial market changed more rapidly, and only the instantaneous influence relation...

Abstract

The invention discloses a cascade effect inference method and device and a computer readable storage medium. The method comprises the following steps: acquiring a time sequence; determining a plurality of sub-time sequences according to the time sequence; determining a relation matrix corresponding to the time sequence according to each sub-sequence; and outputting cascade effect information corresponding to the relation matrix. According to the invention, the accuracy of cascading effect information inference is improved.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a cascading effect inference method, device and computer-readable storage medium. Background technique [0002] In practical applications, there is an influence relationship between objects, and the behavior evolution of some objects can have a significant impact on the behavior evolution of other objects. For example: In the stock market, there is ample evidence that there is a lead-lag effect (causality) among stock prices, that is, the stock prices of some companies show a concomitant response to fluctuations in other stock prices. However, the existing technology research on the influence relationship between objects is directly based on a time series with a long period, and the accuracy of the determined relationship matrix is ​​low, resulting in inaccurate inference of the output cascading effect information corresponding to the relationship matrix . Cont...
