Constrained multiobjective problems are commonly encountered in real-world optimization scenarios, often presenting significant challenges due to the complex nature of the feasible domain and the stringent constraints involved. In constrained multiobjective problems, effectively crossing infeasible regions and utilizing infeasible solutions to preserve population diversity is a significant challenge. While many contemporary constrained multiobjective algorithms have implemented specific enhancements, their overall efficacy remains limited. Therefore, the boundary exploration-bidirectional evolution for constrained multiobjective optimization (BECMO) algorithm is proposed in this article to solve the constrained objective space complexity problem. Initially, BECMO utilizes an evolution strategy that prioritizes an objective function. This strategy guides the populations to converge toward the infeasible-feasible boundary, effectively traversing the challenging infeasible region and carefully determining the relative priorities of objective function evolution and constraint evolution. After boundary exploration, BECMO will identify the constrained and unconstrained Pareto front relationship of the problem and generate bidirectional evolutionary parameters. This strategy enables populations to evolve concurrently from two distinct directions and utilize the superior solution based on the bidirectional evolutionary parameters at a predetermined rate. Comparative experiments demonstrate that BECMO has better performance indicators on a range of three test suites and five real-world application problems than other compared algorithms. It effectively addresses the difficulty of exploring complex infeasible domains, and infeasible solutions are rationally utilized to maintain population diversity. © 2024, The Authors.

During the COVID-19 period, Lecture Recording System is of great significance to the remote and flexible education, and the key issue of the lecture recording automation is the detection of teacher and students. To achieve fast and accurate detection, We applied YOLO algorithm to the detection and adopted Eagleeye pruning method to reduce the amount of parameters and calculation of the YOLO model. We also designed and developed the Intelligent Lecture Recording System based on hisi Hi3531DV200. Experiments on the data set collected from Internet shows that the pruned model can achieve 94.8% precision and 31.25FPS speed on Hi3531DV200, which make the Intelligent Lecture Recording System fast, robust and accurate. © 2023 IEEE.

Face anti-spoofing (FAS) defends the facial image recognition systems against the spoof attacks. While the imperceptible spoof cues in the facial images are usually represented in the images' high-frequency components, existing methods do not fully explore them. In this paper, we introduce wavelet into face anti-spoofing and propose a Cross-frequency Dual-branch network (CDNet), which mainly contains two frequency branches to explore spoof cues from the input facial images' high- and low-frequency components generated by wavelet transforms. In CDNet, we design Frequency Attention Module (FAM) to fuse different internal frequency features learned by two frequency branches, and propose a Complementary Learning Module (CLM) to aggregate the two final frequency features. In addition, we present a resolution-aware Binary Cross-Entropy Loss to balance the training samples with different resolutions. We conduct comprehensive experiments on four datasets, and the results shows that our CDNet performs better than the previous state-of-the-art methods on both intra- and inter-dataset testing.

Test-Time Backdoor Detection for Object Detection Models

Object detection models are vulnerable to backdoor attacks, where attackers poison a small subset of training samples by embedding a predefined trigger to manipulate prediction. Detecting poisoned samples (i.e., those containing triggers) at test time can prevent backdoor activation. However, unlike image classification tasks, the unique characteristics of object detection—particularly its output of numerous objects—pose fresh challenges for backdoor detection. The complex attack effects (e.g., "ghost" object emergence or "vanishing" object) further render current defenses fundamentally inadequate. To this end, we design TRAnsformation Consistency Evaluation (TRACE), a brand-new method for detecting poisoned samples at test time in object detection. Our journey begins with two intriguing observations: 1) poisoned samples exhibit significantly more consistent detection results than clean ones across varied backgrounds. 2) clean samples show higher detection consistency when introduced to different focal information. Based on these phenomena, TRACE applies foreground and background transformations to each test sample, then assesses transformation consistency by calculating the variance in objects confidences. TRACE achieves black-box, universal backdoor detection, with extensive experiments showing a 30% improvement in AUROC over state-of-the-art defenses and resistance to adaptive attacks.

Local Features Meet Stochastic Anonymization: Revolutionizing Privacy-Preserving Face Recognition for Black-Box Models

arXiv

arXiv 2024年

作者： Liu, Yuanwei Jia, Chengyu Xiao, Ruqi Jia, Xuemei Wei, Hui Jiang, Kui Wang, Zheng National Engineering Research Center for Multimedia Software Institute of Artificial Intelligence School of Computer Science Wuhan University China Hubei Key Laboratory of Multimedia and Network Communication Engineering Wuhan University China School of Computer Science and Technology Harbin Institute of Technology Harbin China

The task of privacy-preserving face recognition (PPFR) currently faces two major unsolved challenges: (1) existing methods are typically effective only on specific face recognition models and struggle to generalize to black-box face recognition models;(2) current methods employ data-driven reversible representation encoding for privacy protection, making them susceptible to adversarial learning and reconstruction of the original image. We observe that face recognition models primarily rely on local features (e.g., face contour, skin texture, and so on) for identification. Thus, by disrupting global features while enhancing local features, we achieve effective recognition even in black-box environments. Additionally, to prevent adversarial models from learning and reversing the anonymization process, we adopt an adversarial learning-based approach with irreversible stochastic injection to ensure the stochastic nature of the anonymization. Experimental results demonstrate that our method achieves an average recognition accuracy of 94.21% on black-box models, outperforming existing methods in both privacy protection and anti-reconstruction capabilities.

The neurological condition epilepsy is demanding and even fatal. Electroencephalogram (EEG)-based epilepsy detection still faces various difficulties. EEG readings fluctuate, and different patients have various seizure activity patterns. EEG signal detection is time-consuming and labour-intensive, which puts a strain on medical staff and raises the possibility of erroneous detections. Usually, electrodes are inserted into the scalp or inside the brain for a brief period of time in order to obtain EEG data. It is essential to research efficient cross-patient automatic epilepsy detection techniques. The multi-head self-attention mechanism recognises long-distance dependencies with the same proficiency as it does temporal dynamic correlations between short-term temporal pattern characteristics and sequential relationships. The contextual representations are inputted into a bidirectional long short-term memory network (BiLSTM) so that information can be extracted in both directions. Classification and training are carried out utilising the log SoftMax algorithm. The experiments utilised scalp EEG data from the CHB-MIT database. Sensitivity, specificity, F1-score, and accuracy were computed to be 96.5 percent, 97.04 percent, 96.6 percent, and 96.2 percent, respectively. The results of the experiment show how well the technique works for detecting seizures in several patients utilising multi-channel EEG recordings. The results also demonstrate the method's improved generalisation capabilities and resilience and consistency in collecting seizure patterns. This is particularly critical for the tertiary diagnosis of epilepsy, and the findings indicate that the proposed method significantly improves the accuracy of detection. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2024.

Competition and concurrent engineering (CE) businesses are growing. Faster product creation, quality improvement, manufacturing process adoption, and reduced client demand cost are vital for corporate success. Implement concurrent engineering to make high-quality goods. CE is a parallel, systematic method to design. The chief executive officer (CEO’s) approach impacted how many firms build products. You may use the fundamental ideas of concurrent engineering conversation and the failure mode and effects analysis (FMEA) tool. To provide a smooth and efficient CE environment, conduct the product development process from market research to detailed design. Concurrent engineering is a novel product development (NPD) approach. Concurrency and cross-functional integration separate CE from traditional product development. NPD continues through developing ideas, validation, proof-of-concept validation, Minimum Viable Product development, pre-launch, and post-launch. In other words, product discovery should continue throughout its life span. Each organization's growth operations operate simultaneously. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

This paper evaluates the uplink spectral efficiency (SE) achieved by a reconfigurable intelligent surface (RIS)-aided cell-free massive MIMO system with max-min fairness (MMF) power allocation. We provide an exact closed-form expression for an achievable SE expression which assumes maximum ratio receive combining at the access points (APs) and centralized large-scale fading decoding at the central processing unit. The derived SE expression also accounts for imperfect channel estimation and spatially correlated Ricean fading channels for both direct (APs-users) and cascaded (APs-RISs-users) links. Alongside this, we provide a generalized SE expression and evaluate the performance achieved by local partial minimum mean-squared error combining. Finally, we optimally solve the RIS phase-shift selection problem in order to maximize the aggregate channel gains, and derive a closed-form solution to the MMF power allocation problem. Simulation results validate the effectiveness of the proposed framework in enhancing the unlink SE with resnect to various benchmarks. © 2023 IEEE.

The landscape of cybersecurity in manufacturing exhibits a dynamic interplay between evolving threats and vulnerabilities against innovative defense mechanisms. With the increasing adoption of smart and cloud-controlled technologies, there is a growing emphasis on securing manufacturing systems from cyberattacks. Future trends indicate a shift toward implementing more advanced technologies such as artificial intelligence and machine learning for threat identification, attack detection, and response. In addition, the adoption of secure-by-design principles in product development and the integration of blockchain technology for ensuring the integrity of supply chain data are expected to become more prevalent. As manufacturers continue to digitize and connect their operations, collaboration between industry stakeholders, government agencies, and cybersecurity experts will be crucial in developing robust defense strategies against evolving security threats. This Special Issue provided a platform for the research advancing understanding of and addressing these threats. The article by Rahman et al., “Taxonomy-Driven Graph-Theoretic Framework for Manufacturing Cybersecurity Risk Modeling and Assessment,” presents a taxonomy-driven graph-theoretic model and framework to represent the threat landscape of cybersecurity and identify vulnerable manufacturing assets. The model and framework contain three techniques to address identified research challenges. First, the proposed framework characterizes threat actors' techniques, tactics, and procedures using taxonomical classifications of manufacturing-specific threat attributes and integrates these attributes into cybersecurity risk modeling. Second, using the attack graph formalism, the proposed framework enables concurrent modeling and analysis of a wide variety of cybersecurity threats comprising varying attack vectors, locations, vulnerabilities, and consequences. Third, a quantitative risk assessment approach is presented to
