Застосування адаптивних гіпермоделей у задачах ре-ідентифікації людини

Abstract

This article deals with existing development and implementation approaches to the adaptive hypermodels usage for person re-identification. The research is based on a comparative study of the models performance applied to different data sets, covering both laboratory scenarios and real operating conditions. Main attention is paid to the assessment of key quality indicators, in particular, recognition accuracy (mAP, CMC) and information processing speed, which allows comprehensive coverage of the effectiveness of the methods used. The study focuses on analyzing the impact of dynamic parameter changes on the results of model work, as well as on the study of incremental learning strategies that helps reduce the risk of catastrophic (knowledge loss) forgetting when adapting to new conditions without the need for complete re-training. Thanks to this approach, the system is able to quickly respond to changes in shooting conditions, for example, variations in lighting, angles and other characteristics, which is critically important for the video surveillance systems. Based on the analysis done, promising areas of further research are outlined, aimed at improving adaptive learning algorithms, developing new architectural solutions and optimizing scaling processes. This, in its turn, will contribute to the implementation of more reliable and effective re-identification technologies in modern information systems. The proposed approach combines usage of a hypermodel with an updated deep neural network, the key advantage of which is its high adaptability and stability of learning, ensured by the usage of a dynamic parameter adjustment, using hypermodels. Combination of cross-entropy and triplet losses allows us to effectively form compact and separate features for different identities, as well as increase the model ability to identify an object even in cases of significant variability of input data. The results of the study demonstrate the prospects for integrating adaptive mechanisms into modern re-identification systems, providing increased resistance to changes in operating conditions and a high level of productivity, which is a necessary condition for successful practical application in information technologies.
