Inverse Reinforcement Learning for Preference-Aware Coordination in Multi-Agent Decision Processes
type: item
description: In many collaborative environments, optimal coordination depends on implicit preferences that are not directly observable. This work explores inverse reinforcement learning (IRL) to infer latent reward structures from observed interaction trajectories. A maximum entropy IRL framework is combined with policy optimization to align agent behavior with inferred preferences. The method is validated on 7,800 decision trajectories collected from simulated negotiation and resource allocation environments. Results show that preference-aware policies improve alignment with target outcomes by 21.3% and reduce conflict frequency by 25.7% compared to manually designed reward functions. Furthermore, inferred reward models generalize across similar tasks with less than 10% performance loss. These findings indicate that IRL provides an effective mechanism for capturing hidden objectives in collaborative systems.

description: Scalability and generalization remain key challenges for reinforcement learning-enhanced LLM agents. This study investigates cross-task generalization by introducing a shared policy representation trained across heterogeneous decision-making tasks. The framework is evaluated on a composite benchmark including 10,200 tasks spanning scheduling, routing and strategic planning. A meta-reinforcement learning approach is employed to enable rapid adaptation to unseen tasks. Experimental results demonstrate that the proposed model achieves a 21.6% improvement in zero-shot performance and reduces fine-tuning steps by 37% compared to task-specific models. Additionally, transfer efficiency, measured by performance retention across domains, increases by 29.4%. These findings indicate that shared policy learning can significantly enhance scalability in LLM-based decision systems.

Ontology Construction and Logical Consistency Reasoning for UHV Grid Operation Texts
type: item
description: The operation of Ultra-High Voltage (UHV) power grids generates massive quantities of unstructured textual data, primarily in the form of dispatch logs, maintenance manuals, and accident reports. While these documents contain critical information regarding system states and operational procedures, their unstructured nature hinders automated processing and intelligent decision support. This paper proposes a comprehensive framework for ontology construction and logical consistency reasoning specifically tailored for UHV grid operation texts. By transforming unstructured textual data into a structured knowledge base, we aim to enhance the semantic interoperability of power system data. The methodology involves a domain-specific ontology construction phase that integrates the Common Information Model with linguistic characteristics of operation logs, followed by a semantic reasoning mechanism designed to detect logical inconsistencies in operational commands. We employ deep learning techniques for entity and relation extraction to populate the ontology, subsequently applying description logic rules to validate operational sequences against safety regulations. The experimental results demonstrate that the proposed framework significantly improves the accuracy of identifying unsafe operational directives and conflicting equipment states compared to traditional keyword-based approaches. This research provides a theoretical foundation and practical tools for realizing cognitive intelligence in modern smart grids.

XFEM Prediction of Fatigue Crack Propagation in Ti-6Al-4V Compressor Blades under ThermoMechanical Loads
type: item
description: The structural integrity of aero-engine compressor blades is critical for the safety and reliability of gas turbine engines. These components operate under severe conditions involving high centrifugal forces, aerodynamic pressures, and significant thermal gradients. This paper presents a numerical investigation into the fatigue crack propagation behavior of Ti-6Al-4V compressor blades subjected to complex thermo-mechanical loading conditions. By utilizing the Extended Finite Element Method (XFEM), this study decouples the mesh topology from the geometric discontinuity, allowing for the simulation of arbitrary crack paths without the need for remeshing. The research incorporates temperature-dependent material properties and a modified Paris law to account for the interplay between thermal stresses and mechanical fatigue drivers. The simulation results reveal that thermal gradients significantly alter the stress intensity factors at the crack tip, leading toaccelerated crack growth rates in specific blade regions compared to isothermal mechanical loading alone. The study identifies the leadingedge near the blade root as a critical zone for crack initiation and propagation. These findings provide valuable insights for predictive maintenance strategies and the design of damagetolerant compressor blades.

Dynamic Lifecycle Prediction of FMCG via Multimodal Reviews Combining BLIP and Prophet
type: item
description: The Fast-Moving Consumer Goods (FMCG) industry is characterized by high demand volatility, short product lifecycles, and intense market competition. Accurate prediction of product lifecycles is critical for optimizing inventory management and marketing strategies. Traditional forecasting methods often rely heavily on historical sales data, neglecting the rich semantic information embedded in user-generated content, particularly the interplay between textual reviews and visual imagery. This paper proposes a novel predictive framework that integrates multimodal sentiment analysis with advanced time-series forecasting. We utilize the Bootstrapping Language-Image Pre-training (BLIP) model to extract unified semantic features from consumer reviews, effectively capturing the nuanced sentiment expressed through both text and uploaded product images. These multimodal sentiment indices are subsequently incorporated as external regressors into the Prophet forecasting model, which is adept at handling seasonality and trend shifts. Our empirical analysis, conducted on a large-scale dataset of e-commerce FMCG transactions, demonstrates that the proposed BLIP-Prophet framework significantly outperforms unimodal baselines and traditional time-series models. The results highlight the predictive value of visual consumer feedback in understanding market dynamics and offer a robust tool for decision-makers in the retail sector.

Transaction Flow Anomaly Detection in Real-Time Payment Networks Through Spatiotemporal Graph Representation Learning
type: item
description: The proliferation of digital payment systems has introduced unprecedented challenges in detecting anomalous transaction patterns within real-time payment networks. Traditional rule-based detection methods struggle to capture the complex spatiotemporal dependencies inherent in modern financial transaction flows. This study proposes a novel framework leveraging Spatiotemporal Graph Representation Learning (STGRL) for transaction flow anomaly detection in real-time payment networks. By modeling payment networks as dynamic graphs where nodes represent accounts and edges encode transaction relationships, our approach integrates Graph Neural Networks with temporal learning mechanisms to capture both spatial topological patterns and temporal evolution dynamics. The proposed methodology employs a multi-layered graph convolutional architecture enhanced with attention mechanisms to learn rich node embeddings that encode transaction behavioral patterns. Experimental evaluation on real-world payment transaction datasets demonstrates that our spatiotemporal graph-based approach achieves superior detection accuracy of 96.8% with significantly reduced false positive rates compared to conventional machine learning baselines. The framework proves particularly effective in identifying coordinated fraud rings and sophisticated money laundering schemes that exhibit complex spatiotemporal patterns across the network.

Quantifying the Impact of High-Intensity Interval Training on Chronic Disease Markers using Longitudinal Mixed-Effects Models
type: item
description: The rising prevalence of chronic non-communicable diseases, particularly type 2 diabetes mellitus and cardiovascular pathology, necessitates efficient therapeutic interventions. High-Intensity Interval Training has emerged as a potent modality for improving cardiometabolic health, yet the quantification of its efficacy is often hampered by statistical methodologies that fail to account for the complex, hierarchical nature of longitudinal clinical data. This study utilizes linear mixed-effects models to rigorously quantify the impact of a twelve-week High-Intensity Interval Training protocol compared to Moderate-Intensity Continuous Training on key chronic disease markers, specifically glycated hemoglobin and systolic blood pressure. By employing a random-intercept and random-slope framework, we analyzed data from 142 participants, accounting for intra-individual variability and missing data points inherent in longitudinal trials. Our analysis reveals that while both modalities induce favorable physiological adaptations, the interval training group demonstrated a significantly steeper trajectory of improvement in glycemic control and vascular function. Furthermore, the mixed-effects modeling approach highlighted substantial heterogeneity in individual responsiveness, suggesting that participant-specific factors play a critical role in intervention outcomes. These findings underscore the utility of advanced longitudinal modeling in exercise oncology and chronic disease management, providing a more robust estimate of treatment effects than traditional repeated-measures analysis of variance. The results advocate for the integration of interval training into standard care pathways and demonstrate the necessity of sophisticated statistical frameworks to fully capture the dynamic physiological responses to exercise stimuli.

description: The demographic transition toward an aging society presents unprecedented challenges for traditional community-based elderly care systems, necessitating a paradigm shift toward digital transformation. This paper explores the strategic integration of digital technologies—ranging from Internet of Things sensors to telehealth platforms—into community care frameworks. Utilizing a System Dynamics modeling approach, we analyze the complex, non linear feedback loops inherent in care delivery, technology adoption, and resource allocation. The study constructs a simulation model to evaluate the long-term impact of various digital strategies on service quality, operational efficiency, and financial sustainability. Our findings reveal that while technology implementation offers significant potential for alleviating labor shortages, its success is heavily contingent upon concurrent investments in digital literacy training for the elderly and the interoperability of information systems. The simulation results suggest that a balanced allocation of resources between hardware infrastructure and user education yields the highest sustained improvement in care capacity. This research contributes to the domain of social systems engineering by providing a quantitative decision-support tool for policymakers and care administrators, highlighting the critical importance of a holistic approach to digitalization in the silver economy.

description: We introduce a context-weighted entity function analysis model that infers entity purpose and operational roles without relying on predefined categories. A multi-span encoder aggregates discursive and situational cues over long passages, while a function inference layer computes role distributions using contextual importance metrics. Experiments on three corpora—OpenBooks-ZS, IndustryReports-ZS, and MedText-ZS—show relative improvements of 18.2%, 15.9%, and 17.6% over paragraph-level embedding baselines. The model achieves a 31.4% reduction in context fragmentation and maintains 93.2% stability under document shuffling stress tests. Manual evaluation confirms a 22.7% increase in role inference coherence.

Personalized Treatment Effect Estimation from Observational EHR with Causal Representation Learning
type: item
description: The widespread adoption of Electronic Health Records (EHR) has generated massive repositories of longitudinal patient data, offering unprecedented opportunities for data-driven healthcare and precision medicine. A central challenge in this domain is the estimation of Personalized Treatment Effects (PTE), which aims to predict the individual-level response to specific medical interventions. Unlike prediction tasks in standard supervised learning, PTE estimation is fundamentally a causal inference problem characterized by the absence of counterfactual outcomes in the training data. Furthermore, observational EHR data is plagued by selection bias, where treatment assignments are correlated with patient characteristics, leading to confounding. In this paper, we propose a novel deep learning framework for estimating PTE from high-dimensional, sparse, and irregular EHR data. Our approach leverages Causal Representation Learning to project patient covariates into a latent space where the distribution of control and treated populations is balanced, thereby mitigating selection bias. We introduce a disentangled representation architecture that separates instrumental factors, confounding factors, and adjustment factors, ensuring that the learned representations retain predictive power for the outcome while satisfying the ignorability assumption. We validate our method on both semi-synthetic datasets and real-world clinical cohorts derived from critical care databases. The experimental results demonstrate that our approach significantly outperforms state-of-the-art baselines in estimating heterogeneous treatment effects, providing a robust tool for clinical decision support.

A Digital Twin Framework for Bridge Structural Health Monitoring with Physics-Informed Graph Networks
type: item
description: The aging of global infrastructure necessitates advanced methodologies for real-time Structural Health Monitoring (SHM) to ensure public safety and optimize maintenance schedules. Digital Twin technology, characterized by the seamless integration of physical assets and their virtual replicas, offers a transformative approach to predictive maintenance. However, traditional data-driven models for Digital Twins often suffer from poor generalization in data-scarce regimes, while high-fidelity finite element models are computationally prohibitive for real-time application. This paper proposes a novel framework: a Physics-Informed Graph Network (PIGN) designed specifically for the Digital Twin of bridge structures. By representing the bridge topology as a graph, where sensor nodes communicate via edges defined by physical connectivity, the model explicitly captures spatial dependencies. Furthermore, the integration of governing physical laws directly into the loss function ensures that predictions adhere to fundamental mechanical principles. We demonstrate that this hybrid approach significantly outperforms purely data-driven baselines in trajectory prediction and damage identification, particularly under noisy sensor conditions. The proposed framework reduces the dependency on massive labeled datasets while maintaining the computational efficiency required for continuous monitoring.

Neural Compression of High-Rate Time Series Using Learned Entropy Models and Temporal Priors
type: item
description: The exponential proliferation of Internet of Things (IoT) devices and high-frequency sensor networks has precipitated a crisis in data storage and transmission bandwidth. Traditional lossless compression algorithms, which rely on rigid, hand-crafted statistical models, often fail to capture the complex, non-linear dependencies inherent in high-rate, stochastic time-series data. This paper introduces a novel neural compression framework specifically designed for high-rate time series, leveraging learned entropy models augmented by deep temporal priors. By utilizing a deep autoregressive network to approximate the conditional probability distribution of future samples based on historical context, our method minimizes the discrepancies between the estimated and actual data distributions. This allows for highly efficient entropy coding. We propose a hybrid architecture that combines causal dilated convolutions with a parameterized probability density function to achieve state-of-the-art compression ratios. Extensive experiments on diverse datasets, including seismic sensor streams and financial tick data, demonstrate that our approach significantly outperforms traditional codecs and existing deep learning baselines in terms of bits-per-dimension, while maintaining manageable computational latency.

Latent Diffusion over Dynamic Service Graphs for Uncertainty-Quantified Failure Propagation Prediction
type: item
description: Modern microservice architectures present unprecedented challenges for reliability engineering due to their complex dependency structures and dynamic failure propagation patterns. Traditional monitoring approaches struggle to predict cascading failures because they lack mechanisms to model the stochastic nature of fault diffusion across service graphs. We propose a novel framework that integrates latent diffusion models with temporal graph neural networks to achieve uncertainty-quantified failure propagation prediction. Our approach constructs dynamic service dependency graphs from distributed tracing data, identifying causal relationships including happens-before ordering, mutual exclusion patterns, and pipeline structures. A specialized graph neural architecture learns service representations through multi-task learning objectives spanning node-level, edge-level, and graph-level predictions. The failure propagation dynamics are modeled as a diffusion process in learned latent space, where graph structure refinement through density-based edge definition and sparsification enables efficient uncertainty quantification. Evaluation on production microservice systems demonstrates superior prediction accuracy with 23% improvement in F1-score over baseline methods, achieving 71% reduction in detection latency while providing calibrated uncertainty estimates that enable proactive incident management.

Contextual Bandits with Fairness Constraints for Personalized Ad Delivery at Scale
type: item
description: Personalized advertising has emerged as a dominant paradigm in digital marketing, leveraging online learning algorithms to optimize ad placement decisions in real-time. Contextual Multi-Armed Bandit (MAB) algorithms represent a principled approach to balancing the exploration-exploitation trade-off inherent in sequential decision-making, offering superior performance compared to traditional A/B testing methods in partial feedback environments. However, the deployment of such algorithms in user-facing applications raises critical concerns about fairness and potential discrimination across demographic groups. This paper addresses the challenge of incorporating fairness constraints into contextual bandit frameworks for large-scale personalized advertising systems. We position our work within the broader landscape of online learning paradigms, demonstrating how contextual bandits bridge the gap between simple multi-armed bandits and full reinforcement learning approaches. Through theoretical analysis and empirical validation, we propose Fair-Contextual UCB (FC-UCB), an algorithmic framework that extends the Linear Upper Confidence Bound principle with dynamic fairness penalty mechanisms. Our approach ensures group-level fairness while maintaining sublinear regret bounds comparable to unconstrained methods. Experimental results demonstrate that FC-UCB achieves fairness violations reduction of approximately 68% compared to standard LinUCB, while maintaining cumulative rewards within 4.2% of the optimal unconstrained performance. The robustness analysis reveals superior convergence properties compared to bootstrap-based approaches, with FC-UCB exhibiting consistent fairness maintenance across diverse problem instances. This work contributes both theoretical foundations and practical algorithms for deploying ethical and effective personalized advertising systems at scale.
