Federated learning (FL) encounters significant challenges in heterogeneous client environments, due to statistical heterogeneity affecting the global model’s generalization. To address these issues, we introduce FedGAC, an efficient adaptive ...

Deep neural networks (DNNs) are susceptible to backdoor attacks. Previous researches have demonstrated the challenges in both removing poisoned samples from compromised datasets and repairing contaminated models. These difficulties arise as ...

Augmented Reality (AR) technology opens up exciting possibilities in various fields, such as education, work guidance, shopping, communication, and gaming. However, users often encounter usability and user experience issues in current AR apps, often due ...

The purpose of this study is to analyze changes in the characteristics of multinational and institutional collaboration networks in COVID-19 vaccine clinical trials against the backdrop of the COVID-19 pandemic. Using the Social Network Analysis (SNA) ...

Secure multiparty computation (MPC) is an important means to realize privacy computing (PC). Private set intersection cardinality (PSI-CA) is a variant of an important problem in MPC research, that is private set intersection. PSI-CA ...

• Propose a delegated private set intersection cardinality protocol.
• Build a ...

With the development of augmented reality (AR) technology, the use of mobile AR applications (MAR apps) is rising rapidly in various aspects of people’s everyday lives, such as games, shopping, and education. When compared to traditional apps, AR apps ...

Public security is the topic of common concern of the government and the common people. In order to solve the puzzle of image distortion, being complex in algorithm and being difficult to take into account of the overall structure and details of the image ...

People spend up to one-third of lives asleep, and healthy sleep habits can make a big difference in their quality of life. But in modern society, many people have unhealthy sleep diaries and suffer from various sleep disorders, which may result in ...

This paper presents a systematic study of the thermal activation of coal-gangue and factors that influence this process under different conditions. Our samples were tested and analyzed using Differential Thermal Analysis (DTA), X-ray diffraction (XRD), ...

Copula is an effective method that describes the joint distribution of dependent random variables. Meanwhile, Kendall's tau and Spearman's rho are two common and important measures measuring the dependence for random variables. The expression form of ...

Aimed at the puzzle to realize exchange and integration for heterogeneous data, this paper proposed a sort of data exchange model of heterogeneous database based on middleware unified platform. Based on the mapping of model drive, the data exchange ...

In this paper we introduce a mixture-state document segmentation method based on wavelet and the hidden Markov tree (HMT) models. First we propose a three-state HMT segmentation method that is similar to those in the reference [1]. Then through ...
