    Deep learning DGA malicious domain name detection based on multi-stage feature fusion

    In recent years, cybersecurity issues have emerged one after another, with botnets extensively utilizing Domain Generation Algorithms (DGA) to evade detection. To address the issue of insufficient detection accuracy in existing DGA malicious domain detection models, this paper proposes a deep learning detection model based on multi-stage feature fusion. By extracting local feature information and positional information of domain name sequences through the fusion of Multilayer Convolutional Neural Network (MCNN) and Transformer, and capturing the long-distance contextual semantic features of domain name sequences through Bi-directional Long Short-Term Memory Network (BiLSTM), these features are finally fused for malicious domain classification. Experimental results show that the model maintains an average Accuracy of 93.26% and an average F1-Score of 93.32% for 33 DGA families, demonstrating better comprehensive detection performance compared to other deep learning detection algorithms.

    A road semantic segmentation system for remote sensing images based on deep learning

    With the rapid development of deep learning of computer science nowadays in China, many fields in academic research have experienced the powerful and efficient advantages of deep learning and have begun to integrate it with their own research. To be specific, in the field of remote sensing, the challenge of road extraction from the original images can be effectively solved by using deep learning technology. Getting a high precision in road extraction can not only help scientists to update their road map in time but also speed up the process of digitization of roads in big cities. However, until now, compared to manual road extraction, the accuracy is not high enough to meet the needs of high-precision road extraction for the deep learning model because the model cannot extract the roads exactly in complex situations such as villages. However, this study trained a new road extraction model based on UNet model by using only datasets from large cities and can get a pretty high precision in extraction for roads in big cities. Undoubtedly, this can lead to over-fitting, but its unique high accuracy ensures that the model's ability to extract roads can be well utilized under the situations of large cities, helping researchers to update road maps more conveniently and quickly in large cities.

    DOA estimation technology based on array signal processing nested array

    Research on non-uniform arrays has always been a focus of attention for scholars both domestically and internationally. Part of the research concentrates on existing non-uniform arrays, while another part focuses on optimizing the position of array elements or expanding the structure. Of course, there are also studies on one-dimensional and two-dimensional DOA estimation algorithms based on array spatial shapes, despite some issues. As long as there is a demand for spatial domain target positioning, the development and refinement of non-uniform arrays will continue to be a hot research direction. Nested arrays represent a unique type of heterogeneous array, whose special geometric shape significantly increases degrees of freedom and enhances estimation performance for directional information of undetermined signal sources. Compared to other algorithms, the one-dimensional DOA estimation algorithm based on spatial smoothing simplifies algorithm complexity, improves estimation accuracy under nested arrays, and can effectively handle the estimation of signal sources under uncertain conditions. The DFT algorithm it employs not only significantly improves angular estimation performance but also reduces operational complexity, utilizing full degrees of freedom to minimize aperture loss. Furthermore, the DFT-MUSIC method greatly reduces algorithmic computational complexity while performing very closely to the spatial smoothing MUSIC algorithm. The sparse arrays it utilizes, including minimum redundancy arrays, coprime arrays, and nested arrays, are a new type of array. Sparse arrays can increase degrees of freedom compared to traditional uniform linear arrays and solve the estimation of signal source angles under uncertain conditions, while also enhancing algorithm angular estimation performance.

    Comparison of deep learning models based on Chest X-ray image classification

    Pneumonia is a common respiratory disease characterized by inflammation in the lungs, emphasizing the importance of accurate diagnosis and timely treatment. Despite some progress in medical image segmentation, overfitting and low efficiency have been observed in practical applications. This paper aims to leverage image data augmentation methods to mitigate overfitting and achieve lightweight and highly accurate automatic detection of lung infections in X-ray images. We trained three models, namely VGG16, MobileNetV2, and InceptionV3, using both augmented and unaugmented image datasets. Comparative results demonstrate that the augmented VGG16 model (VGG16-Augmentation) achieves an average accuracy of 96.8%. While the accuracy of MobileNetV2-Augmentation is slightly lower than that of VGG16-Augmentation, it still achieves an average prediction accuracy of 94.2% and the number of model parameters is only 1/9 of VGG16-augmentation. This is particularly beneficial for rapid screening of pneumonia patients and more efficient real-time detection scenarios. Through this study, we showcase the potential application of image data augmentation methods in pneumonia detection and provide performance comparisons among different models. These findings offer valuable insights for the rapid diagnosis and screening of pneumonia patients and provide useful guidance for future research and the implementation of efficient real-time monitoring of lung conditions in practical healthcare settings.

    Bridging the gap in online hate speech detection: A comparative analysis of BERT and traditional models for homophobic content identification on X/Twitter

    Our study addresses a significant gap in online hate speech detection research by focusing on homophobia, an area often neglected in sentiment analysis research. Utilising advanced sentiment analysis models, particularly BERT, and traditional machine learning methods, we developed a nuanced approach to identify homophobic content on X/Twitter. This research is pivotal due to the persistent underrepresentation of homophobia in detection models. Our findings reveal that while BERT outperforms traditional methods, the choice of validation technique can impact model performance. This underscores the importance of contextual understanding in detecting nuanced hate speech. By releasing the largest open-source labelled English dataset for homophobia detection known to us, an analysis of various models' performance and our strongest BERT-based model, we aim to enhance online safety and inclusivity. Future work will extend to broader LGBTQIA+ hate speech detection, addressing the challenges of sourcing diverse datasets. Through this endeavour, we contribute to the larger effort against online hate, advocating for a more inclusive digital landscape. Our study not only offers insights into the effective detection of homophobic content by improving on previous research results, but it also lays groundwork for future advancements in hate speech analysis.
