Abstract

The invention provides an event occurrence probability prediction method and device. The event occurrence probability prediction method comprises the steps of according to prediction index type requirements of each prediction in a preset model set for a predicted event, acquiring prediction indexes corresponding to the prediction index type requirements; applying each prediction model to process the corresponding prediction indexes, and acquiring an output probability corresponding to each prediction model; applying a pre-trained fitting model corresponding to the model set to process the output probability corresponding to each prediction model, and predicting the occurrence probability of the event. According to the event occurrence probability prediction method and device, the accuracy of a prediction result is improved, and thus the effectiveness and the reliability of processing relevant services according to the prediction result are improved.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a method and device for predicting event occurrence probability. Background technique [0002] In many business scenarios, it is often necessary to predict the occurrence probability of various events in the business, so as to adjust or operate the related business according to the predicted probability of occurrence. For example: on the third-party payment business platform, predict the occurrence probability of the user's account being stolen; or, on the financing business platform, predict the occurrence probability of the user's repayment of the loan amount; or, on the insurance business platform, predict the user's claim settlement Probability of events, etc. [0003] At present, a single prediction model is used to predict the probability of occurrence of various events in the business according to the business scenario. For example, on the insurance busine...
