Patent recommendation service has become a major demand of all walks of life in the society. Patent data collection and analysis can not only help enterprises grasp the development status of the industry, but also provide decision support for them in the research and development process of science and technology services. In view of the problem of inaccurate patent recommendation caused by the inconsistency between the search text and the patent text length and the low accuracy of traditional patent recommendation, a word and sentence dual processing model based on Transformer encoder and regularization strategy is proposed to complete the patent recommendation task from the level of sentence granularity and word granularity. The sentence granularity feature extraction module uses the transformer encoder superimposed multi-head attention method to obtain the feature information between the sentence vector groups, so that the sentence vector fuses the feature information of each sentence, and solves the problem of low recommendation accuracy caused by the inconsistent length of the patent text and the search text;The word granularity feature extraction module uses the twin network model to extract the feature information of the sentence granularity vector using the Transformer encoder using the double splicing operation, improve the model performance and model accuracy;Introduce a strategy based on Dropout and symmetric JS divergence regularization, improve the model generalization ability and accuracy. Experiments have proved that it outperforms SBERT, BERT, MGMSN and SVM models in terms of performance. © 2024 IEEE.

Geographic information data finds extensive applications at both the national and societal levels. The decentralized nature of blockchain technology facilitates trust among participants, eliminating the need for centralized institutions and offering a reliable database for many-to-many sharing of geographic information data. This data can be categorized into two parts: geographic data and their corresponding metadata. As of now, mainstream blockchain systems do not support the storage of excessively large data volumes on the blockchain. In contrast to the query functionality of traditional databases, existing blockchain systems are unable to directly query data fields within transactions, and their query methods are limited. This paper introduces a geographic information data query optimization solution based on blockchain technology. It involves the combined storage of both data parts using IPFS and blockchain, reducing on-chain storage redundancy, especially for metadata characteristics. Additionally, it incorporates Bloom filters and inverted index into a tamper-proof index structure, enhancing support for multi-keyword queries within the MPT tree. With this structure, users can access multiple relevant information, optimizing the query efficiency on the blockchain. © 2023 IEEE.

Timely and accurate detection of and response to potentially malicious encrypted traffic is crucial in cybersecurity strategies. Convolutional neural network-based approaches that convert traffic loads into images for analysis have made significant progress in malicious encrypted traffic detection, but they suffer from the challenges of large number of participants, large network size, and high demand for computational resources, especially when edge computing devices are limited. Therefore, there is an urgent need for a lightweight, efficient and accurate malicious encrypted traffic detection model. This paper proposes a malicious encrypted traffic detection model whose core idea is to utilize KL image compression technique. The model first converts the raw traffic data into grayscale images and applies KL transform to compress the images efficiently. Subsequently, a convolutional neural network model with lightweight design is used to classify the compressed image for fast and accurate malicious encrypted traffic detection. After validating on both the public traffic dataset and the lab's self-collected dataset, the results indicate that our method requires just 0.0216 seconds to process a single input sample, achieving an average classification accuracy of 98%. These findings highlight its practicality and excellence in addressing the real-world challenges of malicious encrypted traffic. © 2024 IEEE.

Deep learning is particularly important in the field of time series data analysis, and has been applied to tasks such as marine data prediction. However, there is a’concept drift’ problem in marine observation data, which leads to performance degradation and catastrophic forgetting of traditional deep learning models used in online scenarios. For this reason, this paper proposes OL-TCN, an adaptive temporal convolutional neural network online prediction deep learning model, which is more suitable for marine online learning and inference scenarios. We make the following innovations: Inside the model, model performance is enhanced by incorporating a multi-head attention mechanism and introducing an automatic machine learning enhancement in the residual cell. Outside the model, a model repository approach is used to effectively cope with the complexity and evolutionary challenges of data streams. The experimental results verify that the OL-TCN model is effective and feasible in marine time series processing. © 2024 Knowledge Systems Institute Graduate School. All rights reserved.

Addressing the challenges posed by the insufficient computational power of low-spec devices to achieve the inference efficiency of prevailing deep learning models, alongside the variability in type and shape within industrial metal sheet datasets, while also catering to the demand for high-precision detection, this paper proposes a novel single-stage detection architecture termed MTRNet. In this paper, we introduce three key enhancements: Firstly, to reduce the number of parameters, we propose a novel Partial Depth Convolution (PDC) structure. By minimizing redundant computations, we aim to enhance the efficiency of spatial feature extraction. Secondly, we propose a Convolution Transformer (CTR) structure that replaces the self-attention module with a convolutional module. This modification addresses the computational inefficiency inherent in the self-attention mechanism of existing Visual Transformers (ViT). Finally, we introduce a novel Attention Convolution Transformer (ACTR) structure to enhance the extraction of global and local feature information. This architecture seamlessly integrates the strengths of both attention and convolution mechanisms, working synergistically to improve performance. Our proposed MTRNet network demonstrates superior detection performance compared to existing industrial standards, achieving a detection accuracy of 81.5% on the NEU-DET dataset. © 2024 Knowledge Systems Institute Graduate School.

In this paper, we propose a Federated Privacy-Enhanced Healthcare (FPEH) learning framework based on Gaussian differential privacy and Paillier homomorphic encryption to enhance data privacy protection for IoT-based smart healthcare systems. To address the data privacy issues of the clients in this scenario, we first apply a Gaussian differential privacy-based mechanism to add noise to the parameters in the client models. Secondly, a constant factor is initially introduced to enhance the randomness and unpredictability of the Gaussian noise. Furthermore, a gradient clipping mechanism is also adopted to ensure the effectiveness of the client model after adding noise. Finally, we employ Paillier homomorphic encryption to encrypt the noisy model parameters, further ensuring the security of the original data. We evaluate the proposed method by applying two datasets, namely MNIST and PneumoniaMNIST. Simulation results demonstrate that the proposed method can protect the privacy of the original data from being leaked and achieve a similar test accuracy level as the comparison algorithms. © 2023 IEEE.
