The traffic data is not intuitive and cannot highlight key information about urban traffic conditions. However, traffic data visualization can directly correlate users with the data, and support users to interact with data in a convenient and visual way. Then realize the feedback of blending user wisdom and machine intelligence. This paper investigates a structured survey of the state of the art in the visualization of traffic data. First, we reviewed five representative traffic data visualization methods including WebVRGIS based traffic analysis and visualization system, TripMiner, IoV distributed architecture, SMASH architecture, and LDA-based topic modelling. Meanwhile, we analyzed the traffic datasets that applied in each method. Then we summarize these methods from seven aspects: scalability, data storage, data update, interactivity, reliability, data anomaly detection, and spatiotemporal visualization. In addition, we make a detailed comparative analysis of the key capabilities of five representative traffic data visualization methods in processing traffic big data. Finally, we conclude that the SMASH architecture performs better in processing high speed and large flow traffic data. Moreover, we propose a novel direction for optimizing traffic data visualization techniques.","PeriodicalId":386048,"journal":{"name":"2020 IEEE 6th International Conference on Computer and Communications (ICCC)","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124547558","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 variability (which is a characteristic of biological issues, imaging modality and expert annotators) has not been fully considered in the design of computer algorithms for medical image quantification. So far, few people predict the uncertainty of medical image segmentation. In this paper, we designed a V-shaped network to quantify the uncertainty in prostate MRI image segmentation. We have embedded a feature pyramid attention module in the backbone network, which can extract high-level semantic context information at different scales and provide a pixel-level attention to the decoder. At the same time, the module will not bring a large computational burden. In our experiments, we tested the performance of the proposed method on 55 clinical subjects.","PeriodicalId":386048,"journal":{"name":"2020 IEEE 6th International Conference on Computer and Communications (ICCC)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129541555","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}

To overcome the difficulty of manually extracting expert features, this paper uses deep learning methods to study the communication relationship recognition. First, use the deep learning model to classify the spectrum data directly, and model the communication relationship as a classification problem with time feature data for processing. It is found that the neural network model is easy to fall into a local minimum; in order to limit the impact of the local minimum problem on recognition In this paper, combining the rules of frequency hopping communication to process the data, make the neural network take as few tasks as possible, and then propose the second design scheme, the communication time series classification scheme, and the final recognition rate reaches 97% on the test set. This article uses long and short memory networks and convolutional neural networks to conduct experiments. Among them, the improved VGG network structure has the best recognition rate in communication problems. The factors that affect the recognition rate of neural networks in the identification of communication relationships are discussed in depth, and suggestions on how to adjust these factors are given based on theory and experiment.","PeriodicalId":386048,"journal":{"name":"2020 IEEE 6th International Conference on Computer and Communications (ICCC)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130534089","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}

Therefore, this paper proposes a cross-source scheduling method for heterogeneous data in a cloud environment, which carries out data prefetching before the actual scheduling, greatly reducing the computation amount during scheduling and thus the scheduling resource overhead. Then, all variables are updated, the quality of the heterogeneous data cross-source sub-stream to be scheduled is arranged, and it is regarded as the weight of the sub-stream data, the best quality sub-stream data among the heterogeneous multi-source sub-stream data is selected in the scheduling window each time for scheduling transmission, and the processing of all data sub-streams on paper is finished. The experimental results show that the method proposed in this paper is capable of cross-source scheduling of heterogeneous data in a cloud environment with high load balancing, throughput and acceleration ratios.","PeriodicalId":386048,"journal":{"name":"2020 IEEE 6th International Conference on Computer and Communications (ICCC)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116504684","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}

Due to the limitation of hardware, this problem becomes more challenging compared with the design of conventional digital beamforming schemes. In this paper, we investigate the HBF design for broadband multiuser millimeter wave multiple-input multiple-output systems. By utilizing the alternating minimization method and taking the weighted sum mean square error minimization criterion, a strictly convergent algorithm based on the manifold optimization method is proposed to efficiently tackle the non-convex problem. The algorithm is applicable to the analog beamforming design in both the fully-connected architecture and the partially-connected architecture. Simulation results demonstrate the fast convergence and excellent performance of the proposed scheme.","PeriodicalId":386048,"journal":{"name":"2020 IEEE 6th International Conference on Computer and Communications (ICCC)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121451915","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}

Such noise may be reduced by hybrid active noise control (HANC) methods, as shown in previous work. However, the performance of conventional HANC methods decrease when impulsive interference occurs. To improve the tracking and robustness of such HANC systems, a new hybrid noise control system with anti-pulse variable step size algorithm (APV-HANC) is proposed. By using new variable step size method and HANC structure, the APV-HANC method has better tracking and robustness performance of the whole system when impulsive noise occurs.
