Trojan Virus Detection and Classification Based on Graph Convolutional Neural Network Algorithm

This article proposes a new method for Trojan virus detection and classification based on graph convolutional neural network (GCN) algorithm. By observing the performance evaluation indicators of the model during the training process, the accuracy of the model continued to improve from the initial 64.27% to 88.28% and gradually stabilized, proving that the model can effectively identify Trojan viruses during the training process. In addition, confusion matrix analysis based on the training set shows that the model performs quite well in classification tasks, with an overall accuracy of 91.06%, precision of 89.24, recall of 92.63, and F1 score of 90.91. These indicators indicate that the model can demonstrate good performance in detecting Trojan viruses from various perspectives. On the test set, the model also demonstrated excellent performance, with an accuracy rate of 90.96%, an accuracy rate of 90%, a recall rate of 91.43%, and an F1 score of 90.71. By analyzing the confusion matrix of the test dataset, it can be seen that the classification performance of the model in practical applications is similar to that on the training set, further verifying its good generalization ability. In summary, the experimental results in this article demonstrate that the Trojan virus detection method based on graph convolutional neural networks has high accuracy and stability, and demonstrates superior performance compared to traditional detection methods. This method provides new ideas and technical support for Trojan virus detection in the field of network security, which can effectively respond to increasingly complex network security threats and provide theoretical basis and practical guidance for related research and applications. Through further optimization and improvement, the method proposed in this article is expected to play a greater role in future Trojan virus detection, helping to enhance the level of network security protection.

Assessment Methods and Protection Strategies for Data Leakage Risks in Large Language Models

Large Language Models (LLMs) have demonstrated remarkable capabilities in natural language processing tasks, yet their inherent vulnerabilities to data leakage pose significant security and privacy risks. This paper presents a comprehensive analysis of assessment methods and protection strategies for addressing data leakage risks in LLMs. A systematic evaluation framework is proposed, incorporating multi-dimensional risk assessment models and quantitative metrics for vulnerability detection. The research examines various protection mechanisms across different stages of the LLM lifecycle, from data pre-processing to post-deployment monitoring. Through extensive analysis of protection techniques, the study reveals that integrated defense strategies combining gradient protection, query filtering, and output sanitization achieve optimal security outcomes, with risk reduction rates exceeding 95%. The implementation of these protection mechanisms demonstrates varying effectiveness across different operational scenarios, with performance impacts ranging from 8% to 18%. The research contributes to the field by establishing standardized evaluation criteria and proposing enhanced protection strategies that balance security requirements with system performance. The findings provide valuable insights for developing robust security frameworks in LLM deployments, while identifying critical areas for future research in adaptive defense mechanisms and scalable protection solutions.

Optimization of Personalized Learning Paths in Educational AI Driven by Student Behavior Data

With the advancement of artificial intelligence (AI) and data-driven methodologies, personalized learning has emerged as a transformative approach to education, enabling tailored instruction based on individual student needs. Distance learning has its own pros like the overall experience of students being humble and getting more humble and connected to learning even outside of their home grounds but this seems to take away one of our cardinal principles of optimizing the classrooms by improving what we have. Education systems were historically built around the one-size-fits-all learning model, a rigid structure that cannot account for the variation between students as learners and thus requires an AI-driven approach that customizes learning sequences on-the-fly. We propose a new framework that combines machine learning, reinforcement learning, and behavior analytics to optimize personalized learning paths. Using deep learning methods on a massive amount of data about student interactivity, our model utilizes prior knowledge gained, active participation, and performance on evaluations to restructure tertiary learning sequence. A reinforcement learning agent further enhances path adaptation by continuously optimizing instructional strategies according to real-time student feedback. Our experimental results, conducted on a large-scale educational dataset, demonstrate significant improvements in student engagement, knowledge retention, and learning efficiency. We discuss key challenges such as data sparsity, computational constraints, while outlining future research directions for more robust and interpretable AI-driven learning path optimization.

Combining Blockchain and AI to Optimize the Intelligent Risk Control Mechanism in Decentralized Finance

This study explores the optimized application of combining blockchain (Blockchain) and artificial intelligence (AI) in the intelligent risk control of decentralized finance (DeFi). Although the decentralization and transparency of DeFi have driven financial innovation, they have also introduced risks related to market manipulation, smart contract vulnerabilities, and liquidity. Traditional centralized risk control approaches struggle to adapt. This research proposes a blockchain+AI-based intelligent risk control framework. Blockchain’s tamper-resistance enhances transaction security, while AI’s intelligent learning capabilities improve risk identification. Experimental results show that this model outperforms traditional solutions in detection accuracy (94.1%), false alarm rate (2.1%), and detection latency (180ms), and it remains robust under high market volatility. The findings suggest that combining blockchain and AI can effectively strengthen DeFi risk control, enhance system transparency and security, and provide theoretical and practical directions for future intelligent and automated risk management.

A Low-Complexity Joint Angle Estimation Algorithm for Weather Radar Echo Signals Based on Modified ESPRIT

A low-complexity joint angle estimation algorithm based on a modified ESPRIT technique is proposed for weather radar echo signals. The algorithm employs a novel dimension reduction approach combined with optimized subspace estimation to reduce computational complexity while maintaining estimation accuracy. The proposed method achieves efficient implementation through a truncated convolution operation that preserves the essential angle information of weather signals. A new signal subspace construction technique is developed to handle the non-stationary characteristics typical in weather radar applications. The algorithm incorporates an adaptive thresholding mechanism and parallel processing structures to optimize computational resource utilization. Theoretical analysis establishes performance bounds and validates the algorithm's computational advantages. The Cramér-Rao Lower Bound (CRLB) for the modified algorithm demonstrates theoretical optimality under specified conditions. Extensive simulation results indicate that the proposed method achieves a 65-75% reduction in processing time and 55-65% improvement in memory efficiency compared to traditional implementations. The algorithm maintains robust performance with Root Mean Square Error (RMSE) of 1.2° at medium SNR (5dB) conditions while exhibiting superior stability under array imperfections and signal perturbations. The practical applicability of the algorithm is verified through comprehensive evaluation using simulated weather radar data, demonstrating its effectiveness for real-time weather signal processing applications.
