However, most available studies focused on the field of satellite network routing algorithms, ignoring the impact of topology on the efficiency of inter-satellite networking and the quality of inter-satellite communication. In this paper, we propose a satellite network topology design method based on deep reinforcement learning (DRL), with the goal of reducing the latency of the entire satellite network. To achieve this goal, we first model the satellite network communication scene and formulate the topology optimization problem as a Markov decision process (MDP). Then, we further propose the idea of backbone-point satellites and use DRL to optimize the topology structure. Finally, we conduct extensive experiments on different performances of satellite topology, and we conclude that the network topology constructed in this way can provide lower latency communications than the motif and +Grid topologies, optimized by 8.48% and 42.86% respectively.","PeriodicalId":440430,"journal":{"name":"International Conference on Electronic Technology and Information Science","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130327728","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The application of encryption techniques and the rapid increase in the size of network traffic have placed higher demands on traffic classification. In this paper, we design multi-headed attention (MHA) and deep metric learning (DML) in our model for network traffic classification. In addition, MHA-DML also extracts more subtle and highly differentiated features through the improved triplet measurement loss. Experimental results demonstrate that the model achieves the best classification on all three publicly available web traffic datasets. The MHA-DML guarantees detection accuracy even when facing a classification task with many categories.","PeriodicalId":440430,"journal":{"name":"International Conference on Electronic Technology and Information Science","volume":"399 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113997258","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the accuracy of identifying safety warning bands in oilfields is low, mainly due to the extreme aspect ratios. To solve the above problems, this paper proposes an improved YOLOv5-based method for detecting rotating targets of oilfield warning bands. By adding an additional angle prediction task to the original object detection framework and using a cyclic smooth labelling algorithm to transform the angle regression problem into a classification problem, the horizontal and predicted angle decoders can be combined to obtain the rotation bounding box of the target. This provides a more accurate spatial position representation of the warning band target, making it easier for the network to extract strong discriminative features of the target. Compared with traditional object detection algorithms annotated with horizontal bounding boxes, the rotation bounding box annotated object detection algorithm proposed in this paper significantly improves the recognition performance of safety warning bands and meets practical application requirements.","PeriodicalId":440430,"journal":{"name":"International Conference on Electronic Technology and Information Science","volume":"12715 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129114234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This method first preprocesses the dataset by encoding the data, filling in missing values, and removing outliers. It then uses recursive feature elimination and cross-validation to remove irrelevant features and select relevant features for further model training. The results, compared with other methods using accuracy, precision, recall, and F1 score, show that the proposed method outperforms other models. The interpretable model constructed based on SHAP value reflects the effect of feature values on prediction model results and provides a ranking of feature importance. The experimental results show that the method can effectively improve the accuracy of heart disease prediction, and provide a clear interpretation of the model prediction results. It can be an aid in the treatment and prevention of heart disease.","PeriodicalId":440430,"journal":{"name":"International Conference on Electronic Technology and Information Science","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129168567","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Coherent beam combining (CBC) technology is an effective way to generating high power vortex beams. However, most common coherent combined vortex (CCV) fiber array is currently based on a single-ring structure with limited output power enhancement. In this paper, a dual-ring fiber array is developed to achieve higher output power and improved stochastic-parallel-gradient-descent (SPGD) correction accuracy. To improve SPGD correction speed, cross-grouping method is used. The results show that CCV beam in dual-ring structure can maintain good intensity distribution and mode distribution after SPGD correction.","PeriodicalId":440430,"journal":{"name":"International Conference on Electronic Technology and Information Science","volume":"267 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120976098","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent years, the long short-term memory neural network model (LSTM model) has been widely used in the forecasting of stock prices due to its effectiveness. Nonetheless, few studies have focused on the forecasting ability of the LSTM model based on stock-index prices, with the effectiveness of this field still needing to be further explored. Against this background, this paper first constructs and designs the LSTM model of deep learning. Secondly, through the Min-Max normalization method to the data of three kinds of China A-share stock market indexes collected by Python, this paper carries out algorithm training for the LSTM model. Furthermore, based on the cleaned data, this paper conducts an empirical analysis of the price forecasting ability of the LSTM model, thus testing the accuracy of the LSTM model forecasting through the difference between the predicted and the true price curves. In closing, the paper draws relevant conclusions and puts forward targeted recommendations for improvement.

Dataflow of the systolic array defines computation mapping strategy and memory access and it is one of the most important design points of accelerators. Most conventional accelerator designs choose a single dataflow and optimize around it. This may influence the Processing Element (PE) utilization rate and cause waste of computing resources and energy. This work introduces a self-paced method to alleviate this problem. We analyse and quantify the PE utilization rate related to the three basic dataflows and build a model called PEU-sim to explore workload-oriented flexible dataflow. Experiments show by combining three dataflows, we are able to raise more than 10% of PE utilization rate for most neural networks and we get the highest of 12.4% for MobileNet.","PeriodicalId":440430,"journal":{"name":"International Conference on Electronic Technology and Information Science","volume":"12715 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129948078","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to fulfill this purpose, CAD tools should be precise and efficient. In this paper, we dig into FPGAs, which unavoidably require CAD tools to be configured. A new timing database construction method mainly focusing on reformatting the timing models of programmable interconnections and routing wires is proposed to improve routing efficiency for FPGAs. A contrast experiment has been carried out to compare routing efficiency with original and new database. The results of our experiment show that routing with this new database can implement circuits of high quality (1.000× critical path delay) within less time (0.994× original routing time). And it can at most route resource-demanding circuits within 0.787× original routing time.","PeriodicalId":440430,"journal":{"name":"International Conference on Electronic Technology and Information Science","volume":"598 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132764953","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
