In real-world surveillance, variations in target distance and viewing angle frequently produce partial views and occlusions, leading to missing geometric components and fragmented appearance cues. Such incomplete observations substantially degrade the robustness and generalization of conventional single-frame methods that rely on global appearance representations. To address these challenges, this study proposes a new ship re-identification framework based on dual-stream feature decoupling and temporal variational Bayesian inference. The proposed method explicitly disentangles ship representations into appearance and structural streams, and leverages multi-frame temporal context to infer missing components and enhance discriminability under partial visibility. Specifically, a ResNet-based splitter trained adversarially against two discriminators is employed to decouple the input representation into separate feature streams. The decoupled streams are then modeled over time using a bidirectional LSTM (BiLSTM) together with a visibility-probability estimator. A graph-structured spatial prior, parameterized via a graph attention network (GAT), serves as the variational prior. Given sequential observations, the variational inference module estimates posterior distributions for missing components and performs probabilistic completion in the latent space. The framework is trained end-to-end using cross-entropy and triplet losses. Extensive experiments on the Ship-CH dataset demonstrate that our method achieves 85.67% mAP and 93.67% Rank-1 accuracy, exhibiting superior robustness under occlusion and partial visibility.展开更多

The proposed method explicitly disentangles ship representations into appearance and structural streams, and leverages multi-frame temporal context to infer missing components and enhance discriminability under partial visibility. Specifically, a ResNet-based splitter trained adversarially against two discriminators is employed to decouple the input representation into separate feature streams. The decoupled streams are then modeled over time using a bidirectional LSTM (BiLSTM) together with a visibility-probability estimator. A graph-structured spatial prior, parameterized via a graph attention network (GAT), serves as the variational prior. Given sequential observations, the variational inference module estimates posterior distributions for missing components and performs probabilistic completion in the latent space. The framework is trained end-to-end using cross-entropy and triplet losses. Extensive experiments on the Ship-CH dataset demonstrate that our method achieves 85.67% mAP and 93.67% Rank-1 accuracy, exhibiting superior robustness under occlusion and partial visibility.

摘要Membership Inference Attacks(MIAs)pose a significant privacy risk in machine learning by enabling adversaries to infer whether specific data samples were used during training,particularly in sensitive domains such as social media and mental health analytics.To address this challenge,this paper proposes HEbdMIA,a lightweight homomorphic encryption-based defense that operates at the post-inference stage by encrypting model output logits without requiring retraining or architectural modifications.The proposed approach preserves the relative ordering of predictions while obscuring confidence patterns exploited by MIAs.Experimental evaluation on DepInferAttack and BotInferAttack demonstrates that HEbdMIA achieves a reduction in MIA success rates of 31.0%and 27.3%,respectively,with an associated accuracy decrease of 29.3%and 26.4%,reflecting a controlled privacy and utility trade-off.Additional analysis using precision,recall,F1-score,and ROC-AUC confirms a substantial decline in adversarial inference capability.These findings indicate that HEbdMIA provides an effective,scalable,and deployment-friendly solution for enhancing privacy in real-world machine learning systems.

摘要With the rapid development of Artificial Intelligence of Things(AIoT)technology,its adoption in the field of smart healthcare is becoming increasingly pervasive.Leading cloud service providers like IBM Watson Health now offer neural network inference services tailored for smart healthcare applications-users simply need to send data to the server to get the diagnosis results.However,a growing concern arises regarding the potential compromise of user privacy.Currently,researchers propose the use of secure multi-party computation and homomorphic encryption techniques to address this issue.Nevertheless,further exploration and improvement are needed to mitigate the side effects,such as increased latency and challenges in meeting real-time monitoring requirements.In this paper,we propose a secure homomorphic encryption-based inference framework named SecureBadger for two typical medical inference scenarios:disease diagnosis based on image analysis and health monitoring with smart wearable devices.We design two inference modes-large-scale batch inference and small-scale low-latency inference.Additionally,different ciphertext packaging schemes are designed to enhance inference efficiency for different inference modes,different input data types and different network layers.Experimental evaluations are conducted on several datasets,and the results indicate that SecureBadger can significantly reduce the inference time overhead in both inference modes.

摘要Method of moments(MoM)and identity by descent(IBD)segment methods are two popular algorithms for kinship inference in investigative genetic genealogy(IGG).However,there is no consensus on how or when to use them,and different criteria of IBD lengths or kinship coefficients are applied to consider a true match.In this study,we compared the performance of KING(representing the MoM method)and IBIS(representing the IBD segment method)for kinship inference in homogeneous populations,admixed populations,and sparse SNP panels.Both simulated and real family data were used.In addition,an equivalent threshold-based method for kinship inference was also proposed,based on either the kinship coefficients or the lengths of IBD segments.Results showed that the overall accuracies were 64.97%for homogeneous population and 54.71%for admixed population with KING while they were 72.92%and 70.88%,respectively,with IBIS.IBIS showed low recall and precision rates when the SNP number was below 164k.In contrast,KING performed still robustly with SNP number as low as 10k.Similar results were obtained with real family data.In conclusion,the two methods perform differently and different methods should be used for different scenarios.If the DNA is of high quality or the samples are from admixed populations,the IBD segment method is recommended.If the samples are of low quantity and/or quality,MoM is more appropriate.For more complex scenarios,both methods can be tried.More importantly,there is an urgent need to develop new algorithms to address related issues.

摘要Deploying multimodal large language models(MLLMs)at the network edge is critical for enabling low-latency,privacy-preserving multimodal intelligence.However,the substantial computational and memory demands of MLLMs present significant challenges for deployment on heterogeneous and resource-constrained edge devices.This survey systematically reviews existing approaches aimed at addressing these challenges.We categorize the literature along two complementary dimensions:model-level compression,which focuses on efficient architectural design and parameter reduction,and system-level inference acceleration,which emphasizes runtime optimizations such as scheduling and resource management.In addition,the survey examines the practical applications of edge-deployed MLLMs in domains such as cyber intelligence and embodied intelligence,and discusses emerging research directions,including edge-native model architectures,to further improve the trade-off between intelligence capability and resource efficiency.

摘要The detection of gravitational waves by the LIGO-Virgo-KAGRA collaboration has ushered in a new era of observational astronomy,emphasizing the need for rapid and detailed parameter estimation and population-level analyses.Traditional Bayesian inference methods,particularly Markov chain Monte Carlo,face significant computational challenges when dealing with the high-dimensional parameter spaces and complex noise characteristics inherent in gravitational wave data.This review examines the emerging role of simulation-based inference methods in gravitational wave astronomy,with a focus on approaches that leverage machine-learning techniques such as normalizing flows and neural posterior estimation.We provide a comprehensive overview of the theoretical foundations underlying various simulation-based inference methods,including neural posterior estimation,neural ratio estimation,neural likelihood estimation,flow matching,and consistency models.We explore the applications of these methods across diverse gravitational wave data processing scenarios,from single-source parameter estimation and overlapping signal analysis to testing general relativity and conducting population studies.Although these techniques demonstrate speed improvements over traditional methods in controlled studies,their model-dependent nature and sensitivity to prior assumptions are barriers to their widespread adoption.Their accuracy,which is similar to that of conventional methods,requires further validation across broader parameter spaces and noise conditions.

摘要Large language models(LLMs)have exhibited outstanding performance across a wide range of natural language processing(NLP)tasks.However,the rising prevalence of hardware transient faults has made silent data corruptions(SDCs)in LLMs increasingly problematic,severely degrading output quality and user experience.State-of-the-art protection schemes primarily rely on hardware-assisted algorithm-based fault tolerance(ABFT)or boundary-setting-driven online fault tolerance(FT2)for selective layers,yet these solutions suffer from strict hardware dependencies,substantial overhead,or incomplete coverage.To address these limitations,we propose RetryTrigger,a novel hardware-free fault-aware inference methodology capable of handling all potential faults.During LLM inference,RetryTrigger dynamically collects runtime output features(e.g.,maximum probability,top-k probability gaps,output entropy,logits statistics,and inference latency),which are used to train a LightGBM meta-model.This meta-model accurately predicts whether duplicate inference should be performed,thereby effectively mitigating faults while preserving efficiency without additional hardware dependence.Extensive experiments on seven representative LLMs(including T5-Small,RoBERTa,BioMedBERT,Qwen2.5-Coder-0.5B/7B,MiniMind,and Opt)demonstrate that RetryTrigger reduces SDC rates by up to 95.33%(on average 92.97%)and achieves a minimal performance overhead of 2.4012%(on average 4.1167%),offering a superior balance between reliability and efficiency compared to state-ofthe-art solutions.

摘要Bayesian inference often faces challenges where the likelihood function is difficult to evaluate or lacks explicit expression,known as likelihood-free Bayesian problems,where posterior distributions can only be inferred indirectly through samples generated under specific parameters.Existing methods such as approximate Bayesian computation,synthetic likelihood,and Bayesian optimization focus on addressing these issues.This paper extends Miller et al.’s(2022)sequential neural ratio estimation method for likelihood-free Bayesian problems by transforming likelihood-toevidence ratio estimation into a multi-class problem for efficient posterior estimation.We introduce a new calibration kernel-based ratio estimation method(CKRE),to enhance the original method’s training efficiency and performance.The convergence of our proposed method is proven,and numerical experiments demonstrate its significant improvement in accurately estimating posterior distributions under limited sample generation conditions.

摘要In 6G,artificial intelligence represented by deep nerual network(DNN)will unleash its potential and empower IoT applications to transform into intelligent IoT applications.However,whole DNNbased inference is difficult to carry out on resourceconstrained intelligent IoT devices and will suffer privacy leakage when offloading to the cloud or mobile edge computation server(MECs).In this paper,we formulate a privacy and delay dual-driven device-edge collaborative inference(P4DE-CI)system to preserve the privacy of raw data while accelerating the intelligent inference process,where the intelligent IoT devices run the front-end part of DNN model and the MECs execute the back-end part of DNN model.Considering three typical privacy leakage models and the end-to-end delay of collaborative DNN-based inference,we define a novel intelligent inference Quality of service(I2-QoS)metric as the weighted summation of the inference latency and privacy preservation level.Moreover,we propose a DDPG-based joint DNN model optimization and resource allocation algorithm to maximize I2-QoS,by optimizing the association relationship between intelligent IoT devices and MECs,the DNN model placement decision,and the DNN model partition decision.Experiments carried out on the AlexNet model reveal that the proposed algorithm has better performance in both privacy-preserving and inference-acceleration.

摘要COMPUTATIONAL experiments method is an essential tool for analyzing,designing,managing,and integrating complex systems.However,a significant challenge arises in constructing agents with human-like characteristics to form an AI society.Agent modeling typically encompasses four levels:1)The autonomy features of agents,e.g.,perception,behavior,and decision-making;2)The evolutionary features of agents,e.g.,bounded rationality,heterogeneity,and learning evolution;3)The social features of agents,e.g.,interaction,cooperation,and competition;4)The emergent features of agents,e.g.,gaming with environments or regulatory strategies.Traditional modeling techniques primarily derive from ABMs(Agent-based Models)and incorporate various emerging technologies(e.g.,machine learning,big data,and social networks),which can enhance modeling capabilities,while amplifying the complexity[1].
摘要Robustness against measurement uncertainties is crucial for gas turbine engine diagnosis.While current research focuses mainly on measurement noise,measurement bias remains challenging.This study proposes a novel performance-based fault detection and identification(FDI)strategy for twin-shaft turbofan gas turbine engines and addresses these uncertainties through a first-order Takagi-Sugeno-Kang fuzzy inference system.To handle ambient condition changes,we use parameter correction to preprocess the raw measurement data,which reduces the FDI’s system complexity.Additionally,the power-level angle is set as a scheduling parameter to reduce the number of rules in the TSK-based FDI system.The data for designing,training,and testing the proposed FDI strategy are generated using a component-level turbofan engine model.The antecedent and consequent parameters of the TSK-based FDI system are optimized using the particle swarm optimization algorithm and ridge regression.A robust structure combining a specialized fuzzy inference system with the TSK-based FDI system is proposed to handle measurement biases.The performance of the first-order TSK-based FDI system and robust FDI structure are evaluated through comprehensive simulation studies.Comparative studies confirm the superior accuracy of the first-order TSK-based FDI system in fault detection,isolation,and identification.The robust structure demonstrates a 2%-8%improvement in the success rate index under relatively large measurement bias conditions,thereby indicating excellent robustness.Accuracy against significant bias values and computation time are also evaluated,suggesting that the proposed robust structure has desirable online performance.This study proposes a novel FDI strategy that effectively addresses measurement uncertainties.

摘要Diabetic kidney disease(DKD)with increasing global prevalence lacks effective therapeutic targets to halt or reverse its progression.Therapeutic targets supported by causal genetic evidence are more likely to succeed in randomized clinical trials.In this study,we integrated large-scale plasma proteomics,genetic-driven causal inference,and experimental validation to identify prioritized targets for DKD using the UK Biobank(UKB)and FinnGen cohorts.Among 2844 diabetic patients(528 with DKD),we identified 37 targets significantly associated with incident DKD,supported by both observational and causal evidence.Of these,22%(8/37)of the potential targets are currently under investigation for DKD or other diseases.Our prospective study confirmed that higher levels of three prioritized targetsdinsulin-like growth factor binding protein 4(IGFBP4),family with sequence similarity 3 member C(FAM3C),and prostaglandin D2 synthase(PTGDS)dwere associated with a 4.35,3.51,and 3.57-fold increased likelihood of developing DKD,respectively.In addition,population-level protein-altering variants(PAVs)analysis and in vitro experiments cross-validated FAM3C and IGFBP4 as potential new target candidates for DKD,through the classic NLR family pyrin domain containing 3(NLRP3)-caspase-1-gasdermin D(GSDMD)apoptotic axis.Our results demonstrate that integrating omics data mining with causal inference may be a promising strategy for prioritizing therapeutic targets.
