The evaluation of grassland degradation is an important part of ecological conservation research, and rodent infestation is a significant factor in grassland degradation. The presence of a large number of mouseholes means that the environmental balance of grassland has been destroyed, so the coverage of mouseholes can be used as an evaluation method for grassland degradation levels. In this paper, the image segmentation method is used to segment the mousehole images, Upernet is used as the segmentation network, and Swin Transformer as the Backbone. FAM and FSM modules are added to the Upernet network to solve the target misalignment problem when upsampling the network. The mIoU is improved by 5.3% according to the experimental results. © 2023 SPIE. All rights reserved.

This study aims to optimize the dispatching operation and control of power system to reduce the increased operation cost caused by the uncertainty and volatility of wind power. To achieve this goal, a data model is proposed based on GA genetic algorithm optimized BP neural network. It can predict generator speed and perform network-wide power balancing, thus ensuring the safe and stable operation of the system. The study proceeds in three stages. First, data cleaning and pre-processing are performed on the data obtained from Kaggle. Second, a BP neural network model with 11 input indicators, such as the temperature of generator winding 1 and 2, rotor speed, and hub temperature, is constructed. The output of the model is the generator speed. The weights and thresholds of the BP neural network are optimized by genetic algorithm. Finally, we verify the effectiveness of our approach. By comparing the prediction results based on the BP model only, we demonstrate that the root mean square error of the proposed method is reduced by 31.28%. This confirms that the proposed model is an effective and feasible method for predicting generator speed. In summary, the proposed data model based on GA genetic algorithm optimized BP neural network can provide improved control over wind power variability and reduce operational costs. The results of this study pave the way for further research and application of advanced modeling and optimization techniques in power systems. © 2023 IEEE.

Network representation learning is a technique that embeds the nodes in a network into a low-dimensional vector space, providing strong support for network analysis tasks such as node classification, link prediction, and community detection. This paper provides a summary of the research in the field of network representation learning in recent years. Firstly, the definition of network representation learning is introduced. Then, traditional network representation learning methods are presented, including matrix factorization-based methods, random walk-based methods, and neural network-based methods. However, traditional network representation learning methods can only be applicable to the traditional networks abstracted as the graphs and not applicable to the hypernetworks abstracted as the hypergraphs. Therefore, this paper also introduces hypernetwork representation learning methods, including homogeneous hypernetwork representation learning and heterogeneous hypernetwork representation learning. Finally, this paper summarizes future research directions in network representation learning. © 2023 ACM.

Complete meteorological data is essential for meteorological research. However, due to sensor failure or occlusion, data loss always occurs. In order to deal with this problem, geoscience often uses Kriging and other traditional interpolation methods. Nevertheless, because the traditional method only considers the existing data, it cannot provide accurate reconstruction results when the spatial missing rate is large. Inspired by image inpainting algorithms, we propose a new deep learning method that combines other variables related to missing meteorological variables to provide more effective information for missing regions, and proves the good effect of the method through a series of experiments. To illustrate that our method can maintain good performance under different missing rates, we use the reanalysis data of the European Centre for Medium-Range Weather Forecasts to create a data set with three different missing rates of 30%, 50%, and 70% through the artificial mask. Under different missing rates, the average RMSE of the method based on deep learning decreased by 77% and 31% respectively compared with Kriging and DINEOF. In addition, by combining relevant variables, the accuracy of the deep learning model can be further improved by about 16%. © 2023 SPIE.

This research paper addresses the challenge faced by mobile app developers in converting free app users to premium users. Specifically, we aim to predict customer interest in the premium version of a mobile app by analyzing user behavior and app usage patterns. To accomplish this, we use a dataset of over 50,000 app users and employ machine learning algorithms to develop a model that predicts subscription conversion with high accuracy. Our study finds that features such as total time spent on the app, frequency of app usage, and user engagement with specific features of the app are strong predictors of subscription conversion. We also evaluate several machine learning classifiers and find that the XGBoost classifier outperforms other algorithms in terms of accuracy and precision. Our findings provide insights into customer behavior and highlight the factors that influence subscription conversion, allowing app developers to focus on improving user engagement and providing value-added features to increase the likelihood of subscription conversion. © 2023 IEEE.

Autonomous Intelligent Systems 2025年第1期5卷 1-14页

Federated learning (FL) is a technology that allows multiple devices to collaboratively train a global model without sharing original data, which is a hot topic in distributed intelligent systems. Combined with satellite network, FL can overcome the geographical limitation and achieve broader applications. However, it also faces the issues such as straggler effect, unreliable network environments and non-independent and identically distributed (Non-IID) samples. To address these problems, we propose an intelligent hierarchical FL system based on semi-asynchronous and scheduled synchronous control strategies in cloud-edge-client structure for satellite network. Our intelligent system effectively handles multiple client requests by distributing the communication load of the central cloud to various edge clouds. Additionally, the cloud server selection algorithm and the edge-client semi-asynchronous control strategy minimize clients’ waiting time, improving the overall efficiency of the FL process. Furthermore, the center-edge scheduled synchronous control strategy ensures the timeliness of partial models. Based on the experiment results, our proposed intelligent hierarchical FL system demonstrates a distinct advantage in global accuracy over traditional FedAvg, achieving 2% higher global accuracy within the same time frame and reducing 52% training time to achieve the target accuracy. © The Author(s) 2025.

Layout is a key link in web page design. In addition to PC, there are a large number of mobile terminals for accessing web pages. When the fixed layout is migrated to the mobile terminal, the user experience is likely to be insufficient. For these devices with different resolutions, CSS3 technology adopts different methods to solve the problem. This paper proposes a responsive layout solution based on HTML 5+ CSS3. First, use HTML5 semantic structural tags to transform DIV tags with semantic requirements in fixed layouts. Then through CSS3's media query and flexible layout, we design the responsive layout of the web page layout, and set the responsive code for pictures and text. The experimental research shows that this scheme realizes the free switching and smooth transition of web pages between different terminals and improves the user experience. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

Accurate monitoring and assessment are necessary due to the enormous challenges posed by rapid urbanization to sustainable development and resource management. This study utilizes Sentinel-2 satellite images of Moradabad City, located in Uttar Pradesh, India, to analyze urban growth through a machine learning approach. Sentinel-2 imagery is widely used for land cover monitoring, and images from 2017 and 2023 were selected to assess the rapid expansion of urbanization. Various techniques, including SVM, ANN and minimum distance (MD), were employed for land surface classification. Among these, SVM produced the most reliable results for estimating urban areas, based on both the Kappa coefficient (Kc) and overall accuracy (O.A.). The SVM estimates that in 2017 about 8.308% of the region was classified as an urban area, and from 2023 that number had increased to about 11.64%, which could be a serious concern for Moradabad city's residents. The motivation behind this study to explore the potential applications of machine learning methods for small-scale urban dynamics monitoring and analysis through satellite image analysis. The research advances knowledge of urbanization processes and offers insightful advice for sustainable urban growth in quickly expanding places. © 2024 IEEE.
