Method and device for predicting safety risk level section of food

Abstract

A method and a device for predicting food safety risk level section are provided in the present application. The method includes: obtaining risk level time series data of the food; decomposing the risk level time series data to obtain a plurality of sub-series data; performing point predictions on the plurality of sub-series data to obtain corresponding point prediction results; determining a final point prediction result corresponding to the food risk level time series data based on the point prediction results corresponding to the plurality of sub-series data; determining a prediction residual corresponding to the final point prediction result; and determining a section prediction result by performing section prediction based on the prediction residua. In the present application, more prediction information and quantitative prediction of the uncertainty of future food risks are provided by adding section prediction based on point prediction.
