Method, device and storage medium for predicting permanent residence of guest user

This invention relates to user data management technology in the financial industry, and discloses a method for predicting the permanent residence of customers. The method includes: extracting latitude and longitude information and corresponding time-series information from the customer's embedded data; performing address matching on the latitude and longitude information using a pre-set map library to obtain address information, and extracting location features from the address information; classifying the address information according to the time-series information and location features to obtain a first address dataset; performing clustering operations on the latitude and longitude information based on the first address dataset to obtain a second address dataset, and filtering out location center data from the second address dataset; updating historical location data based on the location center data to obtain the customer's permanent residence. Furthermore, this invention also relates to blockchain technology, where customer historical data can be stored on blockchain nodes. This invention also proposes a device, electronic device, and storage medium for predicting the permanent residence of customers. This invention can improve the accuracy of predicting the permanent residence of financial and insurance users.

Dangerous key scene generation method and system based on big language model retrieval enhancement

The invention relates to a dangerous key scene generation method and system based on big language model retrieval enhancement, and belongs to the technical field of automatic driving simulation testing, and the method comprises the following steps: constructing a scene knowledge base and a trigger condition base based on real traffic accident data; receiving a natural language function test requirement, extracting matched real accident features by using a retrieval enhancement technology, and generating a structured hierarchical scene description; comparing the scene static elements with a pre-labeled map library by adopting a mixed thinking chain compiling strategy with map matching priority; and according to a comparison result, adaptively selecting and multiplexing an existing map file and only generating a dynamic script, or simultaneously generating a static map file and the dynamic script, and finally outputting an executable simulation code. According to the method, a hybrid compiling framework with dynamic and static separation is provided, grammar errors generated by complex road network codes are effectively avoided, and the compilable rate and simulation fidelity of OpenDRIVE and OpenSCENARIO codes are greatly improved.
