Abstract

The invention relates to the field of artificial intelligence, and provides an abnormal data detection method and device, computer equipment and a storage medium. The method comprises the steps: acquiring the user driving behavior characteristics; screening out specified user driving behavior characteristics from the specified user driving behavior characteristic data, constructing a specified isolated tree based on a preset segmentation value, and generating a corresponding isolated forest; calculating the path length of the user driving behavior characteristic data from the root node of the isolated tree to each leaf node; calculating the average path length of all the user driving behavior characteristic data in the isolated forest; calculating an anomaly detection score of the driving behavior characteristic data of each user; and generating an anomaly detection result corresponding to each piece of user driving behavior feature data based on the anomaly detection score. The abnormal data can be quickly and accurately identified from all the user driving behavior characteristic data. The method can also be applied to the field of block chains, and the data such as the anomaly detection score can be stored on the block chain.

Description

technical field [0001] The present application relates to the technical field of artificial intelligence, in particular to a detection method, device, computer equipment and storage medium for abnormal data. Background technique [0002] With the rapid development of the Internet of Vehicles and the Internet, the current automobile market will provide customers with value-added services, such as insurance pricing, freight express billing, etc., by collecting the driving trajectory data of car owners to achieve precise marketing. [0003] Normal driving trajectory data can be generated through the corresponding trajectory APP, or by using mobile phone GPS and other information. However, some existing illegal users will use computer software such as navigation simulation software to falsify driving trajectory data to achieve illegal profits, such as defrauding mileage fees. Since the driving trajectory data generated by computer software forgery is very close to the driving t...
