In order to improve the feature extraction process in the semantic segmentation network and clarify the operating logic of the model, this paper splits the discriminative features according to the pixel's own information and the inter-pixel correlation information. Using two branch networks, relational branch and information branch to focus on the extraction of their own features, and using the fully convolutional segmentation head and the fully-connected segmentation head respectively to make the features more in line with the requirements of the branch itself. In order to make full use of the information contained in the discrepancy between the two branches, a Discrepancy-guided Fusion module is proposed at the feature level, in where the difference information between the features is used as a guide to promote the fusion of the features of the two branches. At the prediction level, with the help of Point-wise Discrepancy Cross Entropy loss, the prediction difference is used to determine the network's attention to each pixel. The effectiveness of the method is verified by extensive experiments on the Cityscapes dataset. © 2023 SPIE.

Document-level neural machine translation (DNMT) faces challenges in integrating context and maintaining semantic consistency. This paper proposes a coarse-to-fine semantic transfer approach that captures both fine-grained and coarse-grained document-level context. By employing a two-stage training strategy with Adapter-enhanced modules, the method ensures effective semantic adaptation from sentence to document levels. Experiments on three datasets demonstrate significant improvements in s-BLEU and d-BLEU metrics, outperforming existing approaches. © 2024 IEEE.

The interaction between SNPs plays a key role in revealing the genetic mechanisms of complex diseases. However, as the order of SNP interactions increases, the number of SNP combinations increases exponentially, presenting a serious combinatorial explosion problem. Although swarm intelligence algorithms can alleviate the combinatorial explosion problem by optimizing search paths and have been widely used in SNP interaction detection, the performance of swarm intelligence algorithms is greatly affected by initialization and search direction. To mitigate these issues, we propose a high-order SNP interaction detection algorithm based on hierarchical clustering and multitask harmony search (abbreviated as HCMHS). In harmony memory initialization, considering that similar SNPs are more likely to form pathogenic combinations, hierarchical clustering is first used to cluster SNPs into different clusters, and then based on these clusters, harmony memory is initialized. In harmony search, considering the correlation between different orders of SNP interactions, the search directions for SNPs of various orders are optimized through a multi-task framework. To verify the performance of HCMHS, we carried out experiments on 58 simulated datasets and one real dataset, and HCMHS achieved the best results compared to nine advanced algorithms. The code of HCMHS is available at https://***/huoluan17-tian/HCMHS. © 2024 IEEE.

Cooperative target detection using infrared and visible images is currently a highly popular approach. This approach is not affected by environmental lighting conditions and can operate around the clock. However, issues such as inaccurate time and spatial synchronization of sensors, target movement, stereo disparity, or other factors leading to positional deviations result in the same target not overlapping completely in different images. This can impact the overall detection performance of the model. To tackle these challenges, this paper introduces a target detection network named TwinFusion-YOLOv9, which integrates features from visible images and infrared images to enhance detection robustness. To ensure the efficiency and accuracy of the solution, a structure suitable for joint target detection based on YOLOv9 was designed. Features from visible and infrared images are separately extracted using a backbone, then fused using a newly designed fusion module, and detection results are obtained using downstream modules. During the training process, an auxiliary detection branch improved from Programmable Gradient information (PGI) proposed in YOLOv9 is incorporated to enhance model accuracy and expedite convergence. Experimental results demonstrate that TwinFusion-YOLOv9 exhibits outstanding performance on public datasets, holding both theoretical and practical significance. © 2024 IEEE.

Timely and accurate recognition of flotation working conditions plays a crucial role in stabilizing process indicators and formulating production operation strategies. Soft sensing methods based on deep learning allow for automatic learning of features from input froth images directly, and is considered a promising flotation monitoring approach. However, the high demand for a large number of labeled samples severely hinders the application of such methods because acquiring froth videos is easily in flotation plants, but manually adding labels to video frames is often expensive. Therefore, a representation-enhanced semi-supervised learning method for flotation working condition recognition is proposed in this paper. Firstly, based on the consistency assumption, a student-teacher network is developed. It leverages massive unlabeled froth image data by ensuring the consistency of model outputs under variations in the input space. Secondly, to guide the student-teacher network learn class-aware cluster representation from unlabeled data, a novel prototypical contrastive learning method with hard negative mixing is proposed. Comparative and ablation experiments on industrial flotation dataset show the effectiveness of the proposed method. © 2024 Technical Committee on Control Theory, Chinese Association of automation.

Since most communications in vehicular networks rely on wireless transmissions, information broadcast by vehicles is highly susceptible to interception and eavesdropping by third parties, making it vulnerable to various attacks. This can result in communication messages being tampered with and the leakage of vehicle locations and identity privacy. From a security perspective, this paper introduces Yao's garbled circuit mechanism, combining random bytes with the solutions of linear equations as identity information assigned to vehicle nodes. By employing dual authentication, the proposed approach addresses issues such as privacy protection, anonymity, replay attacks, and collusion attacks in vehicular networks, thereby enhancing security. Moreover, considering the post-authentication access control scenario, this paper proposes a novel LSSS matrix transformation algorithm for ciphertext hidden access control strategy. It realizes a partially hidden policy, which makes matrix generation more efficient by supporting both AND and OR gates, thus improving the access control efficiency while ensuring security. Performance analysis indicates that in terms of identity authentication, the scheme reduces computational costs by an average of 96.25%, and in access control, the scheme reduces key generation time by an average of 80%.

Materials informatics is a method that combines statistics, machine learning techniques, and high-throughput computing to promote materials discovery and design. In this study, we propose a novel framework based on weighted graph for mapping material compositions to properties. The framework utilizes distributed representations of elemental compositions and incorporates soft attention mechanisms to capture the importance of different elements in the materials. By leveraging attention mechanism and residual network, the model can effectively extract features and generate fixed-length representations for materials, enabling efficient information aggregation. Experimental results on diverse datasets from the Material Project database demonstrate the effectiveness of our proposed method, achieving less errors compared to other methods that do not consider the material structure. This data-driven deep learning method showcases the potential of materials informatics in providing accurate predictions for various material properties. © 2023 IEEE.

Pre-trained language representation-based dependency parsing models have achieved obvious improvements in rich-resource languages. However, these model performances depend on the quality and scale of training data significantly. Compared with Chinese and English, the scale of Vietnamese Dependency treebank is scarcity. Considering human annotation is labor-intensive and time-consuming, we propose a multi-features enhanced multi-task learning framework to convert all heterogeneous Vietnamese Treebanks to a unified one. On the one hand, we exploit Tree BiLSTM and pattern embedding to extract global and local dependency tree features from the source Treebank. On the other hand, we propose to integrate these features into a multi-task learning framework to use the source dependency parsing to assist the conversion processing. Experiments on the benchmark datasets show that our proposed model can effectively convert heterogeneous treebanks, thus further improving the Vietnamese dependency parsing accuracy by about 7.12 points in LAS. © 2024 China National Conference on Computational Linguistics.

Dialect speech recognition has always been one of the challenges in Automatic Speech Recognition (ASR) systems. While lots of ASR systems perform well in Mandarin, their performance significantly drops when handling dialect speech. This is mainly due to the obvious differences between dialects and Mandarin in pronunciation and the data scarcity of dialect speech. In this paper, we propose DialectMoE, a Chinese multi-dialects speech recognition model based on Mixture-of-Experts (MoE) in a low-resource conditions. Specifically, DialectMoE assigns input sequences to a set of experts using a dynamic routing algorithm, with each expert potentially trained for a specific dialect. Subsequently, the outputs of these experts are combined to derive the final output. Due to the similarities among dialects, distinct experts may offer assistance in recognizing other dialects as well. Experimental results on the Datatang dialect public dataset show that, compared with the baseline model, DialectMoE reduces Character Error Rate (CER) for Sichuan, Yunnan, Hubei and Henan dialects by 23.6%, 32.6%, 39.2% and 35.09% respectively. The proposed DialectMoE model demonstrates outstanding performance in multi-dialects speech recognition. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.
