Speaker recognition is a vital component of identity verification and security systems that has made significant progress through the use of deep neural networks. this article examines the comparative performance of two neural network models, namely a one-dimensional convolutional neural network (1D-CNN) and a long short-term memory (LSTM-based) network in identifying individuals based on their recorded voices. the article uses three diverse datasets, including the Raparin Artificial intelligent Lab (RAIL) dataset, which was created locally, and two public datasets, namely the TIMIT dataset and the Jordan dataset. the results show that the proposed 1D-CNN model consistently outperforms the LSTM model and has a significant accuracy rate, especially in the RAIL dataset, which achieves an accuracy of over 95.22%. this study emphasizes the potential of deep learning algorithms in improving sound-based identity recognition and highlights its effects on system security and communications.

Traditional image segmentation models have certain limitations in the field of view, leading to insufficient performance in capturing global information for large-scale tasks and difficulty in integrating multi-scale features, which in turn reduces the accuracy of the algorithm and affects the segmentation effect. this paper proposes a Unet3+ plant leaf disease image segmentation method based on the SK-Attention attention mechanism. this improved attention mechanism introduces a "Selective Kernel" (SK) convolution technology, which can dynamically adjust the size of the convolution kernel to adapt to different field of view requirements, that is, by mixing the outputs of convolution kernels of different scales. the introduction of SK-Attention enhances the network's adaptability and selectivity to different scale features, thereby improving the network's segmentation performance. Finally, the image segmentation experiments conducted on the plant leaf disease dataset prove that this method can effectively improve the segmentation skills of plant leaf disease images, proving its correctness and effectiveness.

Purpose: Discriminating radiation encephalopathy (REP) from brain tumor recurrence is often difficult. this study aims to develop and validate an approach to distinguish REP from post-radiation brain tumor recurrence using machine learning. Methods: this study involved 102 patients diagnosed and treated in our institution between 2020 and 2023. A total of 2153 radiomics features were extracted from contrast-enhanced MRI by using 3D-Slicer software and Pycharm platform. Nine diagnostic models were built and compared based on three selection methods and three classification algorithms. the sensitivity, specificity, accuracy, and area under curve (AUC) of each model were calculated, and based on these the optimal model was chosen. Results: the least absolute shrinkage and selection operator with correlation (LASSO+corr) was chosen as the optimal selection method, which selected 17 important radiomics features. the most promising model was a combination of LASSO+corr as the selection method and logistic regression (LR) as the classification algorithm. the combination models of LASSO+corr with LR, random forest (RF) and support vector machine (SVM) showed sensitivities of 0.88, 0.86 and 0.97, and specificities of 0.98, 0.93 and 0.90 with AUC of 0.9805, 0.9452 and 0.9743, respectively. Conclusion: Radiomics-based machine learning has potential to be utilized in differentiating REP from recurrent brain tumor after radiotherapy accurately.

this paper presents a knowledge graph representation learning framework based on Horn clause rules, designed to efficiently integrate logical information into knowledge graphs (KGs) in continuous vector spaces. Due to the challenge of rule uncertainty, it is difficult to devise a principled framework in continuous vector spaces where encoding the logical background knowledge of rules is usually not straightforward. therefore, we propose a solution that calculates the Horn rule constraint among relations, obtained through iterative optimizationlearning with labeled triplets, objective score functions, and relation modeling. this method enables us to achieve better regulation of rule-based effects, merely enforcing relation representations to satisfy constraints introduced by Horn rules. Finally, we analyze the proposed method on several FB15K datasets. the analysis results demonstrate that our scheme effectively improves the performance of link prediction evaluation on public datasets.
