Complaint early warning method, device, equipment and medium

The invention provides a complaint early warning method and device, equipment and a medium. The method comprises the following steps: obtaining business feature data of a to-be-predicted activity, inputting the business feature data of the to-be-predicted activity into a complaint prediction model, and outputting a complaint prediction result comprising a complaint amount and time relation function corresponding to business features of the to-be-predicted activity, and according to the complaint prediction result of the to-be-predicted activity, complaint early warning is carried out. According to the scheme, the activity features of the to-be-predicted activity can be extracted through the service feature data, the complaint prediction model completes training and verification in advance based on the linear regression algorithm and the predict method according to the historical activity data, and early warning can be performed based on the complaint prediction result output by the complaint prediction model.
