Probability prediction method and system based on beta distribution, terminal, medium and application

The invention belongs to the technical field of machine learning and data analysis, and discloses a probability prediction method and system based on beta distribution, a terminal, a medium and application. The probability prediction system based on beta distribution comprises a prior distribution calculation module used for estimating prior distribution of samples by using historical sample data of multiple stages and using multi-stage iterative calculation; and the probability prediction calculation module is used for obtaining a probability prediction result by utilizing a beta distribution expectation formula and combining the current sample data and the expert prediction data. According to the method, the stage information of the historical sample data and the expert prediction data of the current probability prediction calculation stage are incorporated into the algorithm process, so that the prediction result is more scientific and accurate. According to the method, the confidence level hyper-parameter
