Method and device for predicting data correlation mode of data stream, equipment and medium

The embodiment of the invention discloses a method, a device and equipment for predicting a data correlation mode of a data stream and a medium. The method comprises the following steps of: receiving input data; detecting whether the input data can belong to the existing first mode or not; if yes, recording the input data into a data set of the existing first mode, and updating the existing first mode set; if not, performing correlation mode calculation on the input data and the data recorded in the existing second mode to obtain a calculation result; judging whether the input data can belong to a second mode or not according to the calculation result; if not, generating a new first mode by using the input data, and adding the new first mode into the first mode set; and if yes, recording the input data into the data set of the existing second mode, and updating the set of the existing second mode. According to the method, the data correlation mode of the input data can be identified, and a basis is provided f
