Statistical Anomaly Detection Approach for Field Mapping Validation in Enterprise Payroll Data Migration
type: item
description: Enterprise payroll system migrations from legacy platforms to modern cloud-based solutions present significant data quality challenges, particularly in field mapping validation. This research proposes a statistical anomaly detection framework specifically designed for automated validation of field mappings during Oracle Cloud Payroll to SAP SuccessFactors migrations. The framework employs distribution-based analysis techniques including Kolmogorov-Smirnov tests, Chi-square tests, and multi-threshold outlier detection mechanisms to identify systematic mapping errors, data type inconsistencies, and business rule violations. Experimental validation using a dataset of 50,000 employee records across 120 fields demonstrates that the proposed approach achieves 95.3% detection accuracy while reducing manual validation time by 42%. The framework successfully identified critical anomalies including decimal precision loss in salary calculations, date format inconsistencies in employment records, and null value propagation in benefit deductions. These results establish statistical anomaly detection as a viable automated quality assurance mechanism for enterprise payroll data migrations, offering substantial improvements over traditional rule-based validation methods.

Integrating Ovarian Reserve Biomarkers with Machine Learning for Gonadotoxicity Risk Prediction in Young Female Cancer Patients: A Scoping Review
type: item
description: Cancer treatment-related gonadotoxicity poses substantial threats to reproductive health in young female patients. Current risk stratification frameworks, including ASCO clinical practice guidelines and the Oncofertility Pediatric Initiative Network (O-PIN) classification, rely predominantly on population-level statistics and expert consensus, offering limited capacity for individualized prediction. This scoping review examines the emerging intersection of ovarian reserve biomarkers and machine learning (ML) methodologies for gonadotoxicity risk prediction in young female cancer patients. Through systematic analysis of published literature, publicly available datasets, and clinical decision support tools, this review identifies key biomarkers—including anti-Müllerian hormone (AMH), antral follicle count (AFC), and follicle-stimulating hormone (FSH)—that serve as critical input features for predictive models. ML approaches, particularly random forest classifiers, have demonstrated promising discriminative performance (area under the receiver operating characteristic curve up to 0.87) in predicting primary ovarian insufficiency following chemotherapy. This review further evaluates how artificial intelligence may facilitate personalized fertility preservation pathway selection and clinical workflow integration. Challenges including limited sample sizes, absence of external validation, data heterogeneity, and algorithmic fairness concerns are critically discussed. Recommendations for multicenter prospective registries and standardized evaluation frameworks are proposed to advance clinical translation of AI-assisted oncofertility decision-making.

Fairness-Accuracy Trade-offs in AI Credit Scoring: A Comparative Evaluation of Reweighting and Resampling Strategies Under Multiple Fairness Constraints
type: item
description: The proliferation of artificial intelligence in financial risk assessment has introduced significant concerns regarding algorithmic fairness, particularly in credit scoring systems where biased predictions can disproportionately affect protected demographic groups. This study presents a comparative evaluation of two predominant pre-processing debiasing strategies—reweighting and resampling—applied to AI-based credit scoring algorithms. Using two publicly available benchmark datasets (the UCI German Credit dataset and the UCI Default of Credit Card Clients dataset), we systematically assess the accuracy-fairness trade-offs under three widely adopted fairness constraints: statistical parity, equal opportunity, and equalized odds. Experimental results across three baseline classifiers (Logistic Regression, Random Forest, and XGBoost) indicate that reweighting achieves a more favorable balance between predictive accuracy and fairness when evaluated under equal opportunity and equalized odds constraints, while resampling demonstrates stronger performance in reducing statistical parity differences. The magnitude of accuracy degradation varies substantially depending on the choice of fairness constraint, with equalized odds imposing the greatest accuracy cost across both datasets. These findings provide evidence-based guidance for financial institutions seeking to implement fairness-aware credit scoring systems and suggest that the selection of debiasing strategy should be contingent upon the specific fairness objective prioritized by regulatory and institutional requirements.

Causal Effect Evaluation of Personalized Reminder Strategies on Government Welfare Program Enrollment: A Propensity Score Matching Approach
type: item
description: Government digital service platforms face persistent challenges achieving optimal enrollment rates for welfare programs including SNAP and Medicaid. This research develops a causal inference framework quantifying personalized reminder intervention effects on enrollment completion, addressing selection bias through Propensity Score Matching, temporal dynamics via Difference-in-Differences, and endogeneity through Instrumental Variables. Methodology validation uses simulated observational data incorporating realistic population heterogeneity and non-random treatment assignment. Results demonstrate personalized reminders achieve 14.3 percentage point enrollment increases (p<0.001) after controlling confounding, with heterogeneous effects across age and digital literacy. The framework provides evidence-based guidance for optimizing government platforms per Executive Order 14058 on customer experience modernization.

AI-Enhanced What-If Scenario Analysis in Supply Chain Digital Twins: A Multi-Objective Trade-Off Perspective on Cost, Resilience, and Carbon Efficiency
type: item
description: Global supply chains face compounding disruptions driven by geopolitical tensions, tariff volatility, climate events, and demand uncertainty. Digital twin technology, which creates dynamic virtual replicas of physical supply chain networks, has emerged as a promising instrument for proactive decision-making through simulation and scenario analysis. This paper presents an analytical framework examining how artificial intelligence enhances What-If scenario analysis within supply chain digital twin environments, with a particular focus on multi-objective trade-offs among cost, resilience, service level, and carbon efficiency. By synthesizing recent literature, publicly available datasets, and U.S. federal supply chain digitalization initiatives, the study delineates the mechanisms through which AI enables multi-source data integration, automated scenario generation, cascading disruption prediction, and Pareto-optimal decision evaluation within digital twin architectures. Rather than proposing a new computational model or system implementation, this work offers a structured analytical perspective that bridges the gap between isolated single-module optimization studies and the integrated cross-functional decision-making that modern supply chains demand. The findings highlight a convergent relationship between resilience optimization and carbon reduction, and identify key technical and organizational challenges for practical implementation at the enterprise level.

AI-Enhanced Cross-Asset Liquidity Contagion Pathway Identification and Dynamic Hedging Strategy Optimization: Evidence from U.S. Equity, Bond, and Derivatives Markets
type: item
description: Cross-asset liquidity risk constitutes a persistent threat to financial stability, as demonstrated by the 2007–2009 Global Financial Crisis, the March 2020 COVID-19 market disruption, and the March 2023 banking stress episode. This study investigates the identification of time-varying liquidity contagion pathways across U.S. equity, fixed-income, and derivatives markets, and the optimization of dynamic hedging strategies informed by such pathways. A temporal graph attention network (T-GAT) is constructed from publicly available data—including FRED macroeconomic indicators, CBOE VIX, and Amihud illiquidity measures derived from Yahoo Finance—to capture directional liquidity spillovers among six representative asset proxies. Transfer entropy serves as the edge-weighting mechanism, and the graph structure is updated on rolling 60-day windows. A Proximal Policy Optimization (PPO)-based deep reinforcement learning agent leverages the T-GAT-derived contagion state to allocate hedging positions across assets. Out-of-sample evaluation over the 2022–2024 period indicates that the T-GAT achieves an F1-score of 0.731 in predicting weekly liquidity stress events, representing a moderate improvement over LSTM and static GCN baselines. The contagion-informed hedging agent yields a Sharpe ratio of 0.847, compared to 0.623 for conventional risk-parity allocation, with reductions in maximum drawdown during the March 2023 stress period.

A Comparative Evaluation of Deep Learning Paradigms for Low-Light Image Enhancement: From CNNs to Diffusion Models
type: item
description: Low-light image enhancement (LLIE) has attracted extensive research interest, with approaches spanning convolutional neural networks (CNNs), Retinex-based deep architectures, zero-shot learning, generative adversarial networks (GANs), Transformers, and diffusion models. Despite the proliferation of individual methods, a unified cross-paradigm evaluation under consistent experimental conditions remains absent in the existing literature. This paper presents a systematic comparative study of twelve representative LLIE methods drawn from six distinct algorithmic paradigms. All methods are evaluated on three widely adopted benchmark datasets—LOL-v1, LOL-v2-Real, and SID—using both full-reference metrics (PSNR, SSIM, LPIPS) and no-reference metrics (NIQE, BRISQUE), alongside computational efficiency analysis covering parameter count, floating-point operations, and inference latency. The experimental results indicate that Transformer-based approaches achieve a favorable balance between reconstruction fidelity and perceptual quality, while zero-shot methods offer substantial advantages in inference speed at the cost of quantitative performance. Diffusion-based methods produce perceptually compelling outputs but incur considerable computational overhead. Cross-dataset generalization tests further expose performance degradation across all paradigms when trained and tested on mismatched data distributions. These findings provide practical guidance for selecting LLIE methods under different deployment constraints and evaluation priorities.

A Comparative Analysis of Telemetry-Driven Anomaly DetectionApproaches for Dual-Purpose Operational and SecurityOptimization in Edge Computing Infrastructure
type: item
description: The proliferation of edge computing nodes in enterprise infrastructure has intensified the demand for anomaly detection methods capable of addressing both operational reliability and cybersecurity resilience within resource-constrained environments. This paper presents a comparative evaluation of six lightweight anomaly detection algorithms—Isolation Forest, One-Class SVM, LSTM-Autoencoder, K-Nearest Neighbors, Random Forest, and lightweight 1D-CNN—assessed across a dual-purpose framework that encompasses operational health monitoring and security threat detection. Experiments are conducted on six publicly available benchmark datasets: NASA C-MAPSS and Microsoft Azure Predictive Maintenance for degradation analysis, alongside Edge-IIoTset, UNSW-NB15, CIC-IDS2017, and TON_IoT for cybersecurity evaluation. Performance is measured through accuracy, F1-score, inference latency, and a proposed Dual-Purpose Efficiency Index under both high-performance server and resource-constrained ARM-based edge configurations. Results indicate that tree-based methods achieve the most favorable accuracy-to-latency ratio for edge deployment, while the LSTM-Autoencoder attains the highest detection quality at substantially greater computational cost. Cross-dataset generalization experiments reveal persistent domain shift challenges, particularly for low-frequency attack categories. These findings provide practical algorithm selection guidance for enterprise edge infrastructure scenarios where operational monitoring and security detection must coexist within constrained computational budgets.

Uplift Modelling and Doubly Robust Causal Learning for Bank Marketing Targeting: Optimizing ROI with Coverage–Incremental Profit Curves
type: item
description: Marketing decisions should optimize incremental business value rather than predictive accuracy alone. A response classifier that ranks customers by subscription probability may inefficiently allocate budget by targeting individuals who would subscribe regardless of marketing intervention. Uplift modeling addresses this limitation by estimating the incremental causal impact of an action and enabling ROI-oriented targeting. This study formulates the “who to contact” problem as a causal decision task using the UCI Bank Marketing Dataset, specifically the bank-additional.csv subset (n = 4,119). Since the dataset includes only contacted clients, the treatment is operationalized as channel assignment, where cellular represents treatment and telephone represents control, as recorded in the contact variable. The leakage feature duration is removed following the dataset documentation. Two causal estimators are implemented: a two-model uplift estimator (T-learner) and a doubly robust learner that regresses an augmented inverse probability weighted (AIPW) pseudo-outcome with cross-fitting. Targeting policies are evaluated on a held-out test set using doubly robust policy evaluation with logistic-regression propensity scores clipped to [0.01, 0.99], and performance is assessed through AUUC, Qini, and coverage–incremental profit curves. On the test set (n = 1,236; seed = 42), the two-model uplift method achieves the best uplift ranking (AUUC = 0.0491, Qini = 0.0246). Outcome prediction AUC is 0.726 for a covariate-only model and 0.722 for an S-learner including the treatment indicator, demonstrating that predictive accuracy on outcomes does not identify incremental impact. Under a profit model with revenue (r = 100) and channel cost (c = 1), the two-model uplift generates 5,627.8 incremental profit at 10% coverage and peaks at 7,517.7 around 40% coverage. Sensitivity analysis further indicates that uplift-based targeting becomes increasingly advantageous as intervention costs ri…

An Empirical Evaluation of Prompt Injection Detection and Refusal-Usefulness Tradeoffs Using the deepset/prompt-injections Dataset
type: item
description: Prompt injection is a leading security risk for large language model (LLM) applications because adversaries can embed instructions that override system intent, exfiltrate hidden prompts, or trigger unsafe tool use. This paper presents a fully empirical evaluation of prompt-injection defenses on the public deepset/prompt-injections dataset (662 labeled prompts; 399 benign, 263 injection/attack) using the official train/test split. We compare lightweight detectors that can be deployed as an input gate: a keyword-based rule system, word-level TF-IDF with Logistic Regression (LR), character-level TF-IDF with LR, calibrated linear Support Vector Machines (SVMs), and Complement Naive Bayes. We report attack success rate (ASR), detection F1, and a refusal rate–usefulness tradeoff. On the test split, the best detector is a character TF-IDF + calibrated linear SVM with F1=0.901 and ROC-AUC=0.977, substantially outperforming keyword rules (F1=0.125). When used as a refusal gate, the same family of character models reduces ASR from 1.000 (no gate) to 0.117 at 92.9% usefulness (1 - benign refusal) under a low-false-positive operating point derived from benign-score quantiles on the training split. Error analysis shows that most remaining bypasses are short, multilingual, or typo-heavy injections, indicating that robust defenses require character-level generalization and abstention tuning. Overall, our results quantify the operational tradeoffs between security and usability and provide reproducible baselines for prompt injection detection research.

Temporal Feature Learning Framework for Multi-dimensional Behavior Anomaly Detection in Digital Transaction Platforms
type: item
description: Digital transaction platforms face escalating challenges from sophisticated fraudulent activities that exploit multi-dimensional behavioral patterns across temporal sequences. This research presents a comprehensive temporal feature learning framework designed specifically for detecting anomalous behaviors in complex digital transaction environments. The proposed framework integrates adaptive threshold mechanisms with multi-scale temporal feature extraction, enabling real-time identification of suspicious activities while maintaining low false-positive rates. Through systematic analysis of transaction sequences, user interaction patterns, and network-level behavioral signatures, the framework achieves enhanced detection accuracy across diverse attack vectors including coordinated fraud campaigns and automated malicious account operations. Experimental validation demonstrates superior performance compared to conventional rule-based approaches, with detection precision reaching 94.7% and recall maintaining 91.3% across heterogeneous transaction datasets. The adaptive nature of the framework allows dynamic adjustment to evolving threat landscapes without requiring extensive retraining cycles. , , ,

Accelerating Clinical Trial Recruitment Through Automated Eligibility Screening with Multi-Modal Deep Learning
type: item
description: Clinical trial recruitment remains a critical bottleneck in medical research, with approximately 80% of trials experiencing significant delays due to inadequate patient enrollment. Traditional manual screening approaches require substantial time and resources while yielding suboptimal accuracy in matching patients to appropriate trials. This paper presents a novel multi-modal deep learning framework that integrates structured electronic health record data with unstructured clinical narratives to automate eligibility screening processes. The proposed architecture employs transformer-based encoders for clinical text processing, coupled with specialized neural networks for structured data analysis, unified through an attention-based fusion mechanism. Experimental validation demonstrates substantial improvements over existing methods, achieving 92.3% accuracy in eligibility prediction while reducing screening time by 73%. The framework successfully processes heterogeneous medical data sources, including diagnosis codes, laboratory results, medication histories, and physician notes, enabling rapid identification of suitable trial candidates. Performance analysis across multiple clinical domains confirms the generalizability and robustness of the approach.

Privacy-Preserving Bid Optimization and Incrementality Estimation under Privacy Sandbox Constraints: A Reproducible Study of Differential Privacy, Aggregation, and Signal Loss
type: item
description: The deprecation of third-party cookies has shifted online advertising toward architectures that expose less user-level information and instead rely on coarse on-device signals and differentially private (DP) aggregation for measurement. This transition creates a recurring technical tension: bidding and conversion models require high-fidelity feedback, yet Privacy Sandbox-style constraints enforce signal obfuscation via quantization, missing feature channels, and noisy aggregated reporting. In this paper, we study the end-to-end impact of these constraints on (i) conversion-rate estimation for bid optimization and (ii) incrementality (uplift) estimation for causal measurement. We center the empirical analysis on the publicly released CriteoPrivateAd dataset and the Criteo Uplift Prediction dataset, and we provide a fully reproducible experimental pipeline. Because the official releases are hosted with content-addressed storage and transfer protocols that require authenticated download flows in common research environments, we provide schema-consistent proxy instantiations that match the published feature buckets, label definitions, and scale regimes and that reproduce every table and figure in this manuscript. Across our experimental sweep, we quantify privacy–utility tradeoffs under feature quantization (4–12 bits), user-level DP feature noise (ε∈{0.5,1,2,4,∞}), and DP cohort aggregation at multiple granularities. Results show that (a) removing the “not available” feature bucket drops profit/1k from 47.1908 to 5.6311 (ROI 0.2318→0.0283) while AUC decreases only slightly, highlighting the difference between ranking metrics and economic utility; (b) 8-bit quantization preserves AUC (0.868→0.8677) and yields similar utility in our bidding simulation; and (c) day-level DP aggregation collapses both prediction quality and uplift policy value, while finer aggregation (campaign- and publisher-level) retains partial utility. We discuss implications for Privacy Sandbox measu…

Feature Attribution-Based Explainability Analysis for Market Risk Stress Scenarios
type: item
description: The increasing adoption of artificial intelligence in financial risk management has raised concerns about the transparency and interpretability of stress testing outcomes. This paper presents a feature attribution-based framework for explaining market risk stress scenarios through SHAP (SHapley Additive exPlanations) analysis. The proposed approach addresses the critical gap between advanced scenario generation techniques and regulatory requirements for explainable risk assessments. By decomposing portfolio loss predictions into individual risk factor contributions, the methodology enables risk managers to validate whether generated scenarios align with established economic relationships. Experimental results using Federal Reserve stress test data demonstrate that the attribution framework achieves 87.3% consistency with known financial correlations during crisis periods. The validation mechanism successfully identifies spurious risk factors and quantifies the relative importance of interest rates, equity volatility, and credit spreads across different stress intensities. Comparative analysis against traditional sensitivity analysis shows 34.2% improvement in attribution stability and 28.6% better alignment with domain expert assessments. The framework provides actionable insights for regulatory compliance while maintaining computational efficiency suitable for real-time risk monitoring applications.
