GAN-based data enhancement unsupervised trademark retrieval system and method

Abstract

The invention discloses a GAN-based data enhancement unsupervised trademark retrieval system. The unsupervised trademark retrieval system comprises a GAN data enhancement module, an instance distinguishing module and a trademark retrieval module. The GAN data enhancement module is used for generating a trademark data set and expanding a training set; the instance distinguishing module is used fortraining an unsupervised network and extracting trademark features; and the trademark retrieval module is used for calculating the similarity between the trademark database and the trademark featuresto be retrieved and sorting the trademark features according to sizes. First, a trademark data set is used to train an adversarial generative network. Then, the trained GAN module is used for generating an enhanced data set, and an original trademark data set is added to form a new trademark data set; and finally, applying the new trademark data set to a training instance distinguishing module. Inthe trademark retrieval module, trademark features of a trademark image to be retrieved and a new trademark data set are extracted through a trained instance distinguishing module. According to the method, the problems of difficult data labeling and insufficient data diversity in trademark retrieval are effectively solved.

Description

technical field [0001] The invention relates to the field of artificial intelligence, in particular to a data-enhanced unsupervised trademark retrieval system method based on an adversarial generation network. Background technique [0002] As an important part of intellectual property rights, trademark protection has a profound impact on corporate brand value. At the same time, trademarks symbolize the quality of goods and the reputation of merchants to a certain extent. With the rapid development of the commodity economy, whether it is the number of trademark registration applications, trademark registration examinations or valid registered trademarks, it is almost impossible to manually find similar trademark images. Therefore, the trademark search system is considered to be a powerful tool for law enforcement agencies to handle trademark protection cases. However, at present, it takes a long time for trademark applicants to apply for a new trademark to approval, and mos...
