Problems solved by technology

[0004] However, the prediction accuracy of the regression analysis method depends on the regression function. When the law of historical data is complex, it may not be possible to find a regression function with a high degree of fitting. In this case, the accuracy of the regression prediction result is not ideal.

Abstract

The embodiment of the invention discloses a prediction method and device based on historical data, and the method and device effectively improve the precision of a prediction result. The method comprises the steps: obtaining the historical data of a prediction item, carrying out the training of the historical data through a neural network system, and obtaining a prediction model, wherein the historical data comprises the historical data of the prediction item and the related historical data of the prediction item, and the prediction model reflects the relation between the historical data of the prediction item and the related historical data of the prediction item; obtaining the related actual data of the prediction item, and achieving the prediction of the actual data based on the historical data of the prediction item according to the related actual data and the actual data, obtained by the prediction model, of the prediction item.

Description

technical field [0001] The present application relates to the field of data processing, in particular to a prediction method and device based on historical data. Background technique [0002] At present, there are many application scenarios that need to predict future data based on historical data according to certain rules, such as predicting the number of online users at a certain point in the future or at certain points in time based on the historical number of online users of the application, so that the adaptability can be increased or decreased accordingly computer resources, or push certain services, etc. For another example, predict future network traffic data based on historical network traffic data, or predict future network delay data based on historical network delay data. [0003] The existing more popular forecasting method is the regression analysis method, which finds the functional expression of the historical forecast data and its related historical data t...
