This study proposes a dual-stream BiLSTM framework for household load forecasting that integrates time-series dynamics with histogram-based daily shape features. Unlike existing models relying on weather or external data, the proposed method extracts intrinsic load-shape information directly from normalized daily curves. A multihead attention module fuses temporal and shape representations, enabling adaptive weighting of informative dimensions. Experiments on three real-world datasets show consistent improvements over the baseline BiLSTM, with up to 30.12%, 24.27%, and 19.03% reductions in MAE, RMSE, and SMAPE, respectively. The results highlight the framework’s robustness and efficiency for fine-grained load forecasting without external inputs.
Textual resources are among the most valuable sources of information in cognitive neuroscience (CN) for understanding and investigating brain activity and cognitive processes. Extracting and constructing knowledge graphs (KGs) from these texts can facilitate medical research by providing deeper insights into neurological diseases and brain function. In recent years, the use of large language models (LLMs) in natural language processing (NLP) has become increasingly widespread, significantly enhancing the extraction of meaningful information from large volumes of text. This study proposes a novel approach for constructing and evaluating a specialized knowledge graph, termed the cognitive neuroscience knowledge graph (CNKG), from scientific publications in the field of CN by leveraging the capabilities of GPT-4. During the construction process, GPT-4 is employed to extract relationships among predefined CN concepts from scientific texts. The resulting graph is then refined to maximize its accuracy and representativeness. Finally, the quality and performance of the CNKG are assessed using GPT-4-based evaluation procedures. The evaluation yielded an accuracy score of 0.936. In addition, link prediction analysis demonstrated that the proposed KG possesses satisfactory quality. Furthermore, complex network metrics obtained using Gephi, particularly the average clustering coefficient (0.419541) and graph diameter (13), provided additional evidence supporting the validity of the constructed graph. The CNKG has the potential to support a variety of downstream applications, including semantic query answering, recommendation systems, and research aimed at the diagnosis and treatment of neurological diseases and disorders. Moreover, it may contribute to improving the quality of research services within the field of cognitive neuroscience. Overall, the proposed approach offers considerable potential to enhance the efficiency and accuracy of cognitive neuroscience literature analysis, thereby opening new avenues for scientific investigation and discovery.
The workforce scheduling and routing problem (WSRP) involves assigning tasks across multiple locations while accounting for varying travel times, service durations, time windows, and skill requirements in a wide range of industries, from healthcare to telecommunications. This paper presents a mixed-integer programming model for the WSRP that balances the trade-off between cost and customer satisfaction using a score-generation function and subsequently evaluates the trade-off between solution quality and computation time for several algorithms on well-known datasets. We demonstrate that our model effectively balances cost, service-level agreement satisfaction, and task priorities while providing high-quality solutions in a timely manner. Observing that the best-performing algorithm varies across problem instances, we propose an algorithm selection approach based on a gradient boosting classifier that achieves 89\% of the performance gap between the virtual best solver and the single best solver.
This study proposes a novel variable-gain mechanism with a minimal number of tuning parameters to enhance the performance of conventional backstepping controllers for nonlinear systems while avoiding singularity and peaking phenomena. The proposed approach is simple, computationally efficient, and well suited for real-time implementation without imposing a significant computational burden. Its effectiveness is validated through real-time experiments conducted using a dSPACE DS1104 controller board and a 7.5-kW induction motor (IM). Simulation results demonstrate that the proposed controller outperforms the conventional backstepping controller. Robustness analyses under variations in stator resistance, load inertia, and viscous friction coefficient reveal substantial reductions in the integral squared error (ISE), from 42.78 to 0.73, 67.4 to 1.38, and 3.65 to 0.53, respectively. Experimental results further confirm that the proposed method achieves superior tracking performance and enhanced robustness against disturbances compared with existing methods reported in the literature.
Plant leaf disease detection (PLDD) is a growing active research area with burgeoning practical applications across various sectors such as agricultural monitoring, food security, and environmental conservation. Accurate segmentation and classification of plant leaf diseases remains a key challenge in the field of plant leaf disease prediction. The challenge demands automated methods for the plant disease identification because it needs to develop better crop management systems, which will boost agricultural production. In this article, we provide a systematic review of various machine learning (ML) and deep learning (DL) methods extensively used for PLDD. The review strategy follows a formal protocol, involving structured search, screening, and analysis of studies published between 2020 and 2024. We have proposed a taxonomy of PLDD methods that will be useful for experts and researchers working in this exciting research area. The review thoroughly examines techniques for both segmentation and classification of the PLDD workflow. In addition, we examine several public and private datasets that are accessible to study plant diseases and highlight their significance in developing accurate diagnostic models. The paper also presented multiple performance assessment criteria that researchers can use to evaluate PLDD methods at present and in the future. The study also discusses the current challenges in plant leaf disease classification and offers essential insights about upcoming developments and potential enhancements. The research findings from this study provide essential knowledge that helps experts and researchers to develop automated systems to detect and classify plant leaf diseases effectively.
