Reliable milling monitoring requires calibrated intervention probabilities and evaluation that respects experimental clustering. This methods-and-evaluation study examines Hierarchical Bayesian Adaptive Fusion (HBAF), combining calibrated TabM and Gaussian Naive Bayes experts. MSM provides 927 source-machine cutting paths and 1585 from a historically inspected second machine. Nested development assessment uses 563 paths from 11 experiments; frozen evaluation additionally uses 172 internal-test paths and the second-machine cohort. The development of HBAF achieves MCC 0.6383, PR-AUC 0.8552, and Brier score 0.0773, but equal fusion and a nonhierarchical control remain stronger on several measures. Added component, prefix, scale-sensitivity, and NUTS analyses do not establish general hierarchical-fusion superiority or uniformly valid Laplace uncertainty. Frozen HBAF performance decreases to MCC 0.4587 and PR-AUC 0.5820 internally, and MCC 0.1040 and PR-AUC 0.2809 across machines. The experiment-aware inference also leaves asymmetric-cost superiority unestablished. The contribution is a leakage-safe evaluation framework and a reproducible case study identifying limits of Bayesian adaptive fusion. Historically inspected transfer data, conditional posterior uncertainty, and hypothetical error costs do not support claims of independent cross-machine confirmation or industrial deployment validation.

SQL and NoSQL databases are at risk from injection attacks, which is one of the most serious threats to the security of today’s data-centric systems. To address this issue, this research proposes an architecture for evaluating a new hybrid technique for detecting vulnerabilities by using a mixture of lightweight statistical machine learning techniques and a semantically verified locally installed large language model (LLM). Specifically, the proposed detection architecture consists of three major parts: (1) an initial filtering phase that uses rapid filtering through TF-IDF vectorization and logistic regression; (2) a second phase that implements a confidence-based hybrid decision logic model; and (3) a third phase using a deterministic LLM to process semantically ambiguous queries. In our experimental evaluation of a balanced benchmark of 1000 queries (500 SQL and 500 NoSQL), our proposed hybrid method achieved the highest overall performance, yielding a precision of 0.998, recall of 0.986, and F1-score of 0.992. The individual ML model obtained a lower recall of 0.964 than the standalone LLM but had F1-scores (0.981) much higher than that of standalone LLM (0.667). The hybrid architecture reduced the number of false negatives (generated by the standalone ML models) from 18 to 7 and the number of false negatives generated by the standalone LLMs from 228 to 7. The hybrid architecture achieved very few false positives. Therefore, the use of hybrid ML-LLM detection pipelines will provide both greater robustness and practical effectiveness when doing database security monitoring.

Renewable-generation forecasting is a probabilistic time-series problem in which point accuracy alone is insufficient for operational decision-making. This study proposes a physics-informed Bayesian framework for multi-horizon forecasting of solar, wind, and total renewable generation. The task is formulated as a 15-dimensional target–horizon problem covering three generation families and five forecast horizons: H1, H3, H6, H12, and H24. A leakage-safe data construction protocol generates causal predictors from meteorological observations, generation history, calendar cycles, lagged and rolling statistics, ramp descriptors, and physics-informed transformations. PI-BHTF partitions the 422-dimensional predictor space into solar, wind, temporal-calendar, and cross-context components, encodes them through parallel nonlinear branches, and combines the representations using cross-energy gated fusion. Its neural core uses a heteroscedastic predictive head and Monte Carlo dropout to distinguish input-dependent aleatoric uncertainty from epistemic variability, whereas the final hybrid forecasts are calibrated using residual quantiles computed from a chronologically held-out validation segment. Across three prespecified random seeds, the full PI-BHTF achieved a mean MAE of 0.0797 ± 0.0007 on the internal chronological test and 0.0686 ± 0.0006 on locked external SCADA validation. Performance and calibration varied substantially across target–horizon tasks, including marked short-horizon external undercoverage for wind generation. Component-wise ablation supported semantic feature partitioning and the heteroscedastic head, whereas the physics-informed features, cross-energy gate, and physics-consistency loss did not independently reduce aggregate MAE. PI-BHTF should therefore be interpreted as a reproducibly competitive framework that balances multi-horizon accuracy, structured representation, uncertainty estimation, and external transferability rather than as a universally dominant model.

Modern power transmission grids are increasingly operated under volatile load, variable generation, and near-limit line-flow conditions. In such environments, deterministic line-flow forecasting is insufficient for operational decision support because operators require calibrated risk probabilities, uncertainty intervals, and reliable early warning signals. This article proposes B-TGPRF, a Bayesian Temporal Graph Probabilistic Risk Forecaster for calibrated overload-risk forecasting in power transmission grids. The proposed framework is positioned as a hybrid probabilistic graph-temporal forecasting system rather than as a new end-to-end graph neural network; its novelty lies in the leakage-controlled sequential combination of temporal forecasting, electrical graph descriptors, calibrated Bayesian risk estimation, residual correction, and compact interval uncertainty assessment. The model integrates temporal line-flow, load, and generation features with graph-topological descriptors, operating-regime indicators, residual correction, conformal interval estimation, probability calibration, and a Bayesian risk layer. A leakage-controlled data preparation pipeline was built using an open large-scale benchmark for machine learning applications in transmission grids. The final modeling dataset contains more than 3.48 million observations, 100 selected critical lines, train-only risk thresholds, and chronological train, validation, test, and external-like scenario splits. B-TGPRF was compared with persistence baselines, linear models, Bayesian baselines, tree ensembles, boosting models, neural temporal models, and compact state-of-the-art-style temporal and graph-temporal architectures. On the strict external-like test, B-TGPRF achieved MAE = 0.3650, RMSE = 0.5478, R² = 0.9962, Brier Score = 0.0147, and ECE = 0.0064. The results show that the proposed model provides a strong overall balance between line-flow forecasting accuracy, calibrated risk estimation, compact interval prediction, and low false-positive risk-signaling, while boosting models remain highly competitive for pure risk-class detection.

Distributed seismic sensor networks integrated into the Internet of Things (IoT) infrastructure enable continuous condition monitoring of large-scale engineering structures. During long-term operation, however, measurement channels are subject to sensitivity drift, increased noise, and pulse artifacts that statistically mimic real vibration events. Related deep-learning techniques for noisy and ill-posed inverse problems have demonstrated the value of combining principled physical priors with deep models. Although the application domain differs, the underlying methodological insight—that constrained, physics-aware feature mappings can stabilize learning under noisy and partially observed conditions—directly motivates the use of a parameterized quantum circuit as a nonlinear feature transformer in the present work, where Hilbert space mapping serves as an analogous structural prior for the latent representation. Three principal fault modes are considered in this work, corresponding to the dominant degradation mechanisms observed in long-term seismic instrumentation: sensor drift, increased noise, and sensor failure. Each fault mode produces a distinct signature in the windowed feature space; the proposed model is trained to discriminate between them based on the latent CNN-LSTM-VQC representation. We propose a hybrid quantum-inspired deep-learning model (QC-DL) for the detection and diagnosis of channel-degradation anomalies. The architecture combines a 1D-CNN+LSTM feature extractor with a parameterized variational quantum circuit (VQC) used as a nonlinear feature transformer. All quantum experiments were performed on the QPanda3 CPUQVM simulator. The data were split chronologically prior to windowing to avoid information leakage. On real-world labeled accelerometric data with four operating modes (normal/drift/high-noise/failure), the QC-DL model achieved a macro-averaged F1 score of approximately 0.69 and per-class AUC values in the range 0.88–0.99. The mean early-detection latency was 1.6 s versus 2.1 s for the CNN-LSTM baseline (~24% reduction). An ablation study against a parameter-matched classical MLP showed that the gain is modest and not solely attributable to additional nonlinearity. The reported p-values (p = 0.70, p = 0.29) do not establish statistical significance. The results support the feasibility of hybrid quantum-inspired deep learning for sensor-channel verification, while highlighting the need for evaluation on real NISQ hardware. This paper proposes a hybrid quantum-inspired approach for detecting and diagnosing such anomalies in the time series of distributed seismic networks. The architecture combines a classical temporal feature extraction module based on one-dimensional convolutional layers and a recurrent long short-term memory (LSTM) network, which generates a latent window representation of the signal, with a parameterized variational quantum circuit used as a nonlinear feature processor in a hybrid computational circuit. Experimental validation was performed on real-world labeled data with multiple sensor degradation modes. The evaluation was organized in a scoring framework aligned with autonomous operation through window ranking and threshold alarm generation. In the experiments, the proposed model provided a macro-averaged F1 score of approximately 0.69 and area under the receiver operating characteristic (AUC) curve values in the range of 0.88–0.99 across classes, outperforming baseline deep models. The average early detection latency was 1.6 s versus 2.1 s for the baseline recurrent model (a 24% reduction). An ablative comparison with a control model based on a classical multilayer perceptron of comparable dimension confirmed that the improvement is not limited to the addition of additional nonlinearity. The obtained results indicate the potential of quantum-supported deep learning for improving the reliability of long-term vibration monitoring and verifying the correctness of sensor channels in distributed seismic networks.

Uneven regional socioeconomic growth presents a fundamental economic challenge, as traditional budget allocation models frequently fall short by neglecting spatial topology and spillover effects. By striking a statistically correct balance between social equality and economic efficiency, this study seeks to maximize regional public funds. We present a new hybrid approach that uses Graph Attention Networks (GAT) in conjunction with multi-criteria optimization to model administrative districts as undirected graphs. By combining regularizations for temporal stability and spatial smoothness, the composite loss function scalarizes a logarithmic utility function for efficiency and a differentiable Gini index for equity. The GNN-based model removed major historical funding imbalances, reducing the highest regional funding gap from an 80-fold difference to a 1.08 ratio and reducing per capita funding variance by 92%, according to empirical testing conducted in Kazakhstan’s Almaty region. The system automatically reorganized 208.5 billion KZT (~463 million USD) at the ideal Pareto frontier (α = 0.5), allocating 96.4% of investments to the digitalization sector, which was given priority. According to the results, incorporating spatial topology, which explains 58.7% of choice variability, offers a highly scalable, empirically supported method for improving strategic public administration and reducing institutional stagnation.
