Drug-target interaction (DTI) prediction has an important role in drug discovery, significantly expediting the drug design and development process. This paper proposes a new model, ERW-BiAN, that seamlessly integrates graph embedding representations with deep learning network. Specifically, we utilize an improved graph embedding model, ERW, to generate comprehensive feature vectors for each node within the knowledge graph. Subsequently, these feature vectors are fed into the BiAN model, which leverages an attention mechanism to assign precise weights to sequences. Experimental results demonstrate the superior accuracy and predictive prowess of ERW-BiAN in DTI prediction tasks. Furthermore, the case about COVID-19 shows that ERW-BiAN has the better application potential for predicting drug-target interactions. © 2024 IEEE.

With the rapid advancement of computer vision and artificial intelligence, point clouds have become a pivotal representation of 3D data. However, practical applications of point clouds are hindered by challenges such as noise, structural sparsity, and information occlusion, which complicate computations and degrade the performance of high-precision analyses. While self-supervised learning has proven effective in reducing reliance on annotated data, existing methods predominantly focus on local features, often neglecting global structures and the balance between geometric and semantic information. This paper introduces the Multi-level Consistency Network (MCNet), a novel framework designed to comprehensively explore multi-level feature information in point clouds. MCNet integrates geometric, structural, and high-order semantic supervisory signals, fostering alignment and complementarity of features through self-supervised learning. We propose the Global-Local Synergistic Noise Module (GLSNM), which combines Principal Component Analysis-based Non-Local Noise Addition (PCA-NLNA) with Mask-based Local Noise Injection (Mask-LNI) to balance the preservation of global structures and local details. Additionally, we develop the Multi-level Information Reconstruction Module (MIRM), which employs an attention fusion mechanism to dynamically balance geometric and high-order semantic information, thereby enhancing the model's feature extraction capabilities in complex environments. Extensive experiments demonstrate that MCNet consistently outperforms existing methods across multiple tasks, including meta-classification, few-shot classification, real-world scene classification, fine-grained classification, and segmentation. These results validate the effectiveness of MCNet and its significant contribution to the field of point cloud processing. © 2025, The Authors. All rights reserved.

Object 6D pose estimation is essential for a variety of applications, including autonomous driving, robotic manipulation, and automated harvesting. Due to the influence of different lighting conditions and occlusions, objects with different poses may exhibit significant variations in appearance in different views. This makes the estimation of the 6D pose of objects from a single RGB image a challenging task. This paper proposes a deep learning network capable of simultaneously detecting and estimating the 6D pose (3D rotation + 3D translation) of target objects. As establishing a large-scale dataset using real data is extremely challenging, this paper introduces an automatic collection scheme based on virtual data generated from real images. We conducted experiments on the generated astronaut dataset using our data collection scheme for 6D pose estimation. The experimental results show that the accuracy of 6D pose estimation based on the ADD metric is 96%. Therefore, this method has significant potential and can be extended to other downstream tasks. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

This paper endeavors to devise an ingenious methodology rooted in artificial intelligence, which, in turn, can be effectively employed to identify sundry categories of faults that are closely associated with photovoltaic arrays. This novel approach amalgamates the manifold learning algorithm with a formidable multilayer perceptron neural network (MLP). Intriguingly, it substantiates that the initial reduction in data dimensionality is achieved through the remarkable Isomap algorithm. Consequently, this compressed data is seamlessly channeled into the MLP, thereby yielding remarkable outcomes concerning fault detection. To validate and scrutinize the aforementioned proposition, a quintessential circuit representing a photovoltaic array is initially simulated utilizing the venerable Matlab/Simulink tool. During this simulation, an extensive corpus of both normal and faulty data is meticulously generated. Subsequently, the manifold learning algorithm is artfully applied to drastically diminish the dimensionality of this extensive dataset The resultant compressed data is then deftly fed into the MLP, allowing it to discern the salient characteristics pertaining to the sundry fault types. Through incessant iterations of intensive training, these faults can be astutely detected and discerned with remarkable accuracy. The results conclusively demonstrate the efficacy of combining manifold-based learning and multilayer perceptron neural network in detecting faults in photovoltaic arrays. The proposed method achieves high precision and effectiveness, surpassing the traditional approach by 2.52%. © 2024 IEEE.

In transfer learning, traditional homogeneous transfer learning assumes similar data and feature distributions between the source and target domains, focusing primarily on parameter sharing to enhance model performance. However, heterogeneous transfer learning for topic model, disparities in data and feature distributions lead to negative transfer, diminishing the effectiveness of topic extraction. This research explores alternative methods for heterogeneous transfer learning in topic model beyond traditional parameter sharing, seeking to maximize the utilization of source domain knowledge and features, mitigating the interference of negative transfer. We propose a novel approach for cross-domain topic transfer learning by combining feature fusion and balancing data and labels. Including applying dual-supervised techniques for handling label dependencies, employing function constraints and data enhancement to adjust data distributions, and utilizing feature fusion techniques to mitigate feature distribution disparities. Additionally, we introduce a topic knowledge distillation method, leveraging topics from the source domain to guide and optimize topic generation in the target domain. In practical applications, this method enhances animal disease topic mining by integrating feature knowledge from the animal diseases dataset and the 20 Newsgroups dataset. The experiments verify the effectiveness of this method, bridging gaps in topic generation and advancing the application of topic modeling in complex and dynamic contexts. © 2024

In this paper, we propose a novel method of reconstructing 3D shapes from single-view images based on an adversarial refiner. Generative Adversarial mechanism is adopted between the coarse-volumes generation stage and the refinement stage. In the coarse-volumes generation stage, a Context Aware Channel Attention Module (CA-CAM) and a VoxFocal Loss are designed to reconstruct the coarse-volume shapes as complete as possible. Furthermore, an adversarial refiner is proposed to adaptively optimize the coarse-volume shapes and remove redundant voxels by adding the discriminator into refiner. On the challenging large synthesis-image dataset ShapeNet and the real-world dataset Pix3D, ARShape-Net demonstrated significant quantitative and qualitative improvements compared with the state-of-the-art methods. © 2021, Springer Nature Switzerland AG.

A series of methods using image semantics to assist in extracting named entity recognition have been proposed recently. However, in these multi-modal named entity recognition methods, there may be problems of visual semantic missing and weak semantic constraints in multi-modal representations. For this reason, we propose a multi-scale visual semantic enhanced for multi-modal named entity recognition method. This method uses a variety of visual features for collaborative representation to obtain more complete visual semantics, integrates semantic information in multi-scale visual features through the multi-modal feature fusion module, to generate multi-scale visual semantic features, and transmits its semantics to text features to obtain semantically enhanced multi-modal text representations. The visual entity perceiver is used to semantically constrain the multi-scale visual semantic features to learn consistent visual semantics. The multi-task label decoder is called to jointly mine the fine-grained entity semantics of the multi-modal text representation and text features, to enhance the semantic accuracy of the prediction features, and solve the problem of semantic bias, thereby further improving the accuracy of named entity recognition. In the two multi-modal named entity recognition datasets (Twitter-2015, Twitter-2017), compared with 10 methods such as HvpNet, MNER-QG, RGCN, etc., the average F1 value of this method increased by 0.85% and 1.45% respectively. In addition, visualization and comparative analysis were conducted on the recognition results, visual features, and text features of methods such as MSVSE, UMT, MAF, and HvpNet in different multimodal data scenarios with varying entity types and quantities. This further validated the effectiveness of the text-based methods. © 2023, The Authors. All rights reserved.

The recurrent neural network model based on attention mechanism has achieved good results in the text summarization generation task, but such models have problems such as insufficient parallelism and exposure bias. In order to solve the above problems, this paper proposes a two-stage Chinese text summarization generation method based on Transformer and temporal convolutional network. The first stage uses a summary generation model that fuses Transformer and a temporal convolutional network, and generates multiple candidate summaries through beam search at the decoding end. In the second stage, contrastive learning is introduced, and the candidate summaries are sorted and scored using the Roberta model to select the final summary. Through experiments on the Chinese short text summarization dataset LCSTS, ROUGE was used as the evaluation method to verify the effectiveness of the proposed method on Chinese text summarization. © 2023 SPIE.

Fast reconstruction of multiphase microstructures based on statistical descriptors

引用

Physical Review E 2022年第5期105卷 055301-055301页

作者： DongDong Chen Zhi Xu XiaoRui Wang HongJie He ZhongZhou Du JiaoFen Nan School of Computer and Communication Engineering Zhengzhou University of Light Industry Zhengzhou 450000 China Guangxi Key Laboratory of Images and Graphics Intelligent Processing Guilin University of Electronics Technology Guilin 541004 China

In this paper, we propose a hierarchical simulated annealing of erosion method (HSAE) to improve the computational efficiency of multiphase microstructure reconstruction, whose computational efficiency can be improved by an order of magnitude. Reconstruction of the two-dimensional (2D) and three-dimensional (3D) multiphase microstructures (pore, grain, and clay) based on simulated annealing (SA) and HSAE are performed. In the reconstruction of multiphase microstructure with HSAE and SA, three independent two-point correlation functions are chosen as the morphological information descriptors. The two-point cluster function which contains significant high-order statistical information is used to verify the reconstruction results. From the analysis of 2D reconstruction, it can find that the proposed HSAE technique not only improves the quality of reconstruction, but also improves the computational efficiency. The reconstructions of our proposed method are still imperfect. This is because the used two-point correlation functions contain insufficient information. For the 3D reconstruction, the two-point correlation functions of the 3D generation are in excellent agreement with those of the original 2D image, which illustrates that our proposed method is effective for the reconstruction of 3D microstructure. The comparison of the energy vs computational time between the SA and HSAE methods shows that our presented method is an order of magnitude faster than the SA method. That is because only some of the pixels in the overall hierarchy need to be considered for sampling.
