Electronic medical record mining based on relationship classification has become a hot topic in the field of healthcare. However, existing models classification, most them use single-layer attention, it results relatively simple feature representation and is easy to lose information during training. Therefore, this paper proposes method dual channel attention. Firstly, 1 combines BERT(Bidirectional Encoder Representation from Transformers), GRU(Gate Recurrent Unit) Global Attention, while 2 Subject_object_mask_generation So Attention. Specifically, we module specify corresponding positions subject object within text. And Attention used focus attention between object. Secondly, outputs two channels are concatenated. Finally, perform concatenated results. We evaluated public dataset CMeIE(Chinese Medical Information Extraction), experimental showed that improved model's accuracy, recall F1 values increased by 2.2%, 0.03% 1.3% respectively, compared baseline. It indicates our certain advantages other methods.

This paper proposes an integration of recent metaheuristic algorithm namely Evolutionary Mating Algorithm (EMA) in optimizing the weights and biases deep neural networks (DNN) for forecasting solar power generation. The study employs a Feed Forward Neural Network (FFNN) to forecast AC output using real plant measurements spanning 34-day period, recorded at 15-minute intervals. intricate nonlinear relationship between irradiation, ambient temperature, module temperature is captured accurate prediction. Additionally, conducts comprehensive comparison with established algorithms, including Differential Evolution (DE-DNN), Barnacles Optimizer (BMO-DNN), Particle Swarm Optimization (PSO-DNN), Harmony Search (HSA-DNN), DNN Adaptive Moment Estimation optimizer (ADAM) Nonlinear AutoRegressive eXogenous inputs (NARX). experimental results distinctly highlight exceptional performance EMA-DNN by attaining lowest Root Mean Squared Error (RMSE) during testing. contribution not only advances methodologies but also underscores potential merging algorithms contemporary improved accuracy reliability.

Abstract Amid the rise of mobile technologies and Location-Based Social Networks (LBSNs), there’s an escalating demand for personalized Point-of-Interest (POI) recommendations. Especially pivotal in smart cities, these systems aim to enhance user experiences by offering location recommendations tailored past check-ins visited POIs. Distinguishing itself from traditional POI recommendations, next approach emphasizes predicting immediate subsequent location, factoring both geographical attributes temporal patterns. This approach, while promising, faces with challenges like capturing evolving preferences navigating data biases. The introduction Graph Neural (GNNs) brings forth a transformative solution, particularly their ability capture high-order dependencies between POIs, understanding deeper relationships patterns beyond connections. survey presents comprehensive exploration GNN-based recommendation approaches, delving into unique characteristics, inherent challenges, potential avenues future research.

In the rapidly advancing field of cancer genomics, identifying new genes and understanding their molecular mechanisms are essential for targeted therapies improving patient outcomes. This study explores capability Graph Convolutional Networks (GCNs) integrating complex multiomics data to uncover intricate biological relationships. However, inherent complexity GCNs often limits interpretability, posing challenges practical applications in clinical settings. To enhance explainability, we systematically compare two state-of-the-art interpretability methods: Integrated Gradients (IG) SHapley Additive exPlanations (SHAP). We quantify model performance through various metrics, achieving an accuracy 76% Area Under ROC curve is 0.78, indicating model’s effective identification both overall predictions positive instances. analyze explanations provided by IG SHAP gain more knowledge decision-making processes GCNs. Our framework interpret contributions omics features GCN models, with highest score observed feature MF:UCEC KIF11. approach identifies novel clarifies mechanisms, enhancing interpretability.
