Abstract

The invention relates to the field of software monitoring of rack operation and maintenance, in particular to a model fault detection method and device, computer equipment and a storage medium. The method comprises the steps of obtaining a stability index and a correctness index of a model to be evaluated and a stability index and a correctness index of a model variable in the model to be evaluated; Obtaining a model score according to a to-be-evaluated model, the stability index and the correctness index of the model variable and a preset fuzzy judgment matrix; Obtaining a model scoring weight parameter; And obtaining a model comprehensive score according to the model score and the model score weight parameter, and when the model comprehensive score is lower than a preset threshold, determining that the model has a fault. According to the model evaluation, the score of the overall health degree of the model is obtained by comprehensively considering various parameters such as the stability and correctness of the model and the stability and correctness of variables. a comprehensive evaluation result of the model health degree is output based on the comprehensive evaluation system so as to judge whether the model is in a normal state.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a model fault detection method, device, computer equipment and storage medium. Background technique [0002] A model refers to an object that constitutes an expression purpose of objectively explaining the morphological structure through subjective consciousness with the help of physical or virtual representations (objects are not equal to objects, not limited to entities and virtual, not limited to plane and three-dimensional). Make necessary simplifications to the researched entity, and describe its main characteristics with appropriate realization forms or rules. The resulting imitation of the system is called a model. [0003] The online model mainly includes machine learning models and statistical models. The evaluation of the running status of online models in the industry is mainly through periodic observation of model scores and variable distributions, and ca...
