A Big Data Analytics Approach for Dynamic Feedback Warning for Complex Systems

Abstract EN

With the development of science and technology, the application of big data is becoming more and more widespread, and it has gradually expanded to various fields such as economy and commerce.

Since the 2008 international financial crisis, the mainstream economics has shown deficiencies to a certain extent.

On the one hand, the expressions pursued by mainstream economic theories are too strict, restricting its processing capabilities.

On the other hand, the linearization method ignores the diversity, complexity, and variability of changes in the economic system, which may ignore the emergence of some serious crises.

Due to the increasing distance between theoretical models and practice, theoretical models cannot guide the practice and sometimes even mislead the latter.

In this paper, we propose a method of dynamic feedback early warning based on big data, which uses the LPPL model to fit parameters.

Finally, we used this method to analyze the case of the A-share disaster.

The research results show that the method makes the early warning coefficients of dynamic and complex systems more scientific and accurate.
