Embodiment Construction
[0027] In order to enable those skilled in the art to better understand the solutions of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present application.
[0028] With the development of technology, smart devices have entered people's lives. Smart devices can collect a large amount of data based on sensors or the Internet, and meet people's diverse needs based on a large amount of data. With the passage of time, more and more data have brought great difficulties to data processing. In order to realize the processing of a large amount of data, the fingerprint method came into being. The fingerprint method refers to abstracting the collected data into high-dimensional vectors, treating them as unique "fingerprints", and then establishing a fingerprint database, when data processing is required Matching at the time, so as...

The application discloses a target fingerprint database construction method, device, electronic equipment and storage medium. The method includes: obtaining a first fingerprint library that matches the target space; migrating data in the first fingerprint library to a second fingerprint library through a migration learning algorithm, the data in the first fingerprint library including reference points corresponding to The data of the second fingerprint library is the fingerprint library corresponding to the target space; select part of the reference points to calculate the positioning accuracy of the second fingerprint library; the positioning accuracy of the second fingerprint library does not reach the preset positioning accuracy , using the rest of the reference points and the reinforcement learning algorithm to increase the positioning accuracy of the second fingerprint library to obtain the target fingerprint library. Through the migration learning algorithm and the reinforcement learning algorithm, the target fingerprint database can be quickly constructed while ensuring that the constructed target fingerprint database has a high positioning accuracy.
Description
Technical field [0001] This application relates to the field of positioning technology, and more specifically, to a method, device, electronic device, and storage medium for constructing a target fingerprint database. Background technique [0002] With the development of science and technology, more and more sensors have appeared in people's lives to collect all kinds of information. With the passage of time, these sensors collect more and more data, and the processing of these data becomes more and more difficult. Therefore, the fingerprint method came into being. The fingerprint method abstracts the collected data into a high-dimensional vector as a A unique fingerprint, and establish a fingerprint library, and use the fingerprint library to match when data processing is needed to achieve rapid data processing. [0003] However, the establishment of the fingerprint database requires the collection of a large amount of data, and the complexity of the fingerprint database is relat...
