Firstly, to enhance the detection network's multi-scale expression ability and sensitivity to the target, a residual module that integrates the attention mechanism replaces the BottleNeck module of the backbone network. This design improves the network's ability to extract features and locate targets at a fine-grained level. Secondly, the CIOU loss function replaces the original loss function, improving the stability of the bounding box regression process. Thirdly, the K-means++ clustering algorithm is used to generate anchors suitable for the dataset in this paper. Furthermore, the object detection dataset in foggy scenes is further enriched based on the atmospheric scattering model. Experimental results indicate that the proposed method's mAP in light fog, medium fog and dense fog scenes is increased by 7.4%, 6.05% and 6.36%, respectively, compared to the original YOLOv5s. This improvement in accuracy significantly reduces the missed detection rate and false detection rate, effectively enhancing object detection performance in foggy weather.","PeriodicalId":177416,"journal":{"name":"Conference on Electronic Information Engineering and Data Processing","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114556073","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}

Process-Aware Information Systems (PAIS), supported by Business Process Management (BPM), can provide programming paradigms for IoT's business processes. However, the heterogeneity and continuity of IoT data make it difficult for traditional PAIS to handle continuous events. One of the keys to solving this problem is to encapsulate the processing logic of heterogeneous, streaming IoT data from different sources in a unified manner, generate business events of interest to the business process, and integrate them into the business process. An event-publish/subscribe mechanism-based IoTService model can integrate IoT events into business processes and enable PAIS to respond to physical world changes.

It is difficult to be monitored continuously in the practice of teaching and learning. The existing model of metacognitive ability is still in theoretical research and lacks effective model construction technology to externalize metacognition. The online learning behavior data contains rich metacognitive information. In contrast, the previous methods based on statistical analysis or traditional machine learning cannot fully extract the internal temporal and semantic features implied in the data. This study uses the self-attention mechanism and the recurrent neural network sequence model to deeply explore and analyze learners' online learning behavior and interactive text. A new evaluation model of metacognitive ability is constructed to represent learners' metacognitive ability. The research takes natural online learners' behavior data as the object to carry out experimental verification and analysis. The results show that the model's accuracy in representing metacognitive ability reaches 85.21%, which verifies the model's effectiveness.","PeriodicalId":177416,"journal":{"name":"Conference on Electronic Information Engineering and Data Processing","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131957360","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}

Oceanic eddy can cause changes in Sea Surface Height (SSH) and will make the SSH around the center of the oceanic eddy to be higher or lower than the surrounding area, so the identification of oceanic eddy can be achieved by detecting the change of SSH. Traditionally, radar altimeter is an important means to measure the sea surface height, but its resolution is low, so it can’t effectively detect sub-mesoscale oceanic eddies. With its all-time, all-weather, wide-swath and high-resolution characteristics, Synthetic Aperture Radar (SAR) has become a research hotspot in oceanic eddy remote sensing detection. It uses radar antennas from different angles of view to form a baseline, called interferometric SAR, which can achieve the measurement of SSH. In this paper, a signal level simulation model of oceanic eddy for spaceborne cross-track interferometric SAR(XTI-SAR) is established, and an evaluation method based on ideal interferometric factors is introduced. In the experiments, we analyze the influence on the error of oceanic eddy SSH measurement at different sea states. The results show that the increase of wind speed will increase the height measurement error of oceanic eddy, and the difference of wind direction will cause obvious changes in the height measurement error.","PeriodicalId":177416,"journal":{"name":"Conference on Electronic Information Engineering and Data Processing","volume":"331 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123100636","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, most vulnerabilities of input parsing programs are triggered in the particular state of the program, so existing directed greybox fuzzing works face path explosion problem when they fuzz the input parsing program and need more ability to explore the particular state of the program. To address the above problem, we propose a call-relationship-based fitness function. The main idea is to use the function call relationship to guide directed fuzzing before reaching the target. Call-relationship-based fitness function extracts the function calls and call relationship from the program, uses an intra-procedural reachability analysis to get all concerned edges, and constructs the fitness function based on the edges. Based on the above method, we implemented the directed greybox fuzzing IPDF and evaluated it with the mainstream directed greybox fuzzers Beacon and AFLGo on real-world programs. Evaluation of IPDF showed that IPDF found vulnerabilities faster than the state-of-the-art directed greybox fuzzers. The experimental results showed that the speed of MDGF is 3.01 times faster than that of AFLGo and 1.15 times faster than Beacon.","PeriodicalId":177416,"journal":{"name":"Conference on Electronic Information Engineering and Data Processing","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132731911","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}

Comprehensive comparative experiments with nine baseline algorithms are carried out on three benchmark datasets which include Amazon-Book Dataset, Yelp2018 Dataset, and Gowalla Dataset.
