Abstract

The invention discloses an accident analysis model training method, device and equipment. The method comprises the following steps: acquiring an accident sample set for a to-be-analyzed mechanism; the accident sample set comprises an accident positive sample and an accident negative sample; different accident samples correspond to different time periods; the label of the accident positive sample is used for representing that the to-be-analyzed mechanism has an accident in the corresponding time period; the features of the accident positive sample comprise a first event feature of an event occurring in the to-be-analyzed mechanism within a first preset duration before the accident occurs, and a second event feature of an event occurring in the to-be-analyzed mechanism within a second preset duration after the accident occurs; the label of the accident negative sample is used for representing that no accident occurs in the to-be-analyzed mechanism in the corresponding time period; the features of the accident negative sample comprise a third event feature of an event occurring in the to-be-analyzed mechanism in a corresponding time period; constructing an accident analysis to-be-trained model; and according to the accident sample set, training an accident analysis to-be-trained model to obtain an accident analysis model.

Description

technical field [0001] The embodiments of this specification relate to the field of computer application technology, and in particular to an accident analysis model training method, device and equipment. Background technique [0002] In the course of various business executions, various accidents usually occur. For example, production accidents, leaking accidents, security accidents, etc. [0003] In order to facilitate emergency management, it is usually necessary to analyze the factors that affect the occurrence of accidents, so as to facilitate subsequent improvement measures to prevent accidents. Influencing factors include, for example, the degree of production safety regulation, the effectiveness of confidentiality measures, and the strength of production process supervision. [0004] But at present, it is difficult to analyze the influencing factors of the accident. Contents of the invention [0005] In order to solve the above technical problems, the embodiment ...
