Since it is limited by the requirement of protecting privacy and trade secrets, data can't be effectively shared among enterprises. Federated learning is an effective method to solve this problem, but there are some performance bottlenecks, information security issues and data trust issues still existed, which need to be improved in combination with other advanced technologies to meet the practical requirements. This paper combines the blockchain technology with federated learning technology, and uses decentralized blockchain system to replace the traditional centralized federated learning architecture. We adopt training method of updating models to achieve machine learning. In this way, we can avoid transmission of intermediate computing data and achieve mechanism of node access, model evaluation, motivation and audit with combination of block chain. In terms of the algorithm, the horizontal federated learning adopts the integrated learning algorithm, and the vertical federated learning adopts the deep learning algorithm. It will be described in detail below.","PeriodicalId":354966,"journal":{"name":"Proceedings of the 5th International Conference on Computer Science and Application Engineering","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127302314","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 electron cooler is one of the most significant facilities in HIAF of Spectrometer Ring (SRing). With the electron cooler, SRing could generate high quality and high intensity ion beam for the experiments. The electron cooler in HIAF was designed to produce 600KeV electron beam. To achieve this design target, high voltage needs to reach 600kV maximum and ripple wave less than 1*10-4. A new control system was designed for the high voltage platform which uses cascaded transformer construction. The system makes use of XGS-PON network as the main means of communication. Zynq 7015 as the CPU of the embedded controller. The controller integrated 2 DAC ports with 100KS/S and 4 ADC ports with 200KS/S for high voltage modules setting and high voltage divider monitor, 8 low-speed ADC ports for auxiliary power supplies, and the environment sensors. The embedded Ubuntu Linux and the EPICS frameworks were programmed in the controller, all of the control parameters were sent through channel access protocol. No need for host computer to participate in control logic, only used for display. The hardware mentioned above interacts with the operating system through the FPGA part of Zynq. The FPGA is programed as a coprocessor for communicating, data processing and interlock control. Corresponding drivers are integrated in the Linux system at the same time.","PeriodicalId":354966,"journal":{"name":"Proceedings of the 5th International Conference on Computer Science and Application Engineering","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125560610","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}

Within this framework, we used the linear fractional integral autoregressive (ARFI) model to derive the analytical expression of information storage calculated at multiple time scales. We used the information storage expression derived from the ARFI model and then collected the information storage of MEG through positive, negative and neutral stimuli and finally calculate it.

However, for a variety of reasons, research institutions have been faced with the scarcity of anomaly samples. One solution is using generative adversarial network (GAN) to generate extra samples for data augmentation. In this paper, we draw on the idea from online knowledge distillation to improve the self-attention GAN, and propose a new framework called Online Knowledge Distillation -Self Attention Generative Adversarial Network (OKD-SAGAN). We introduce a new module called connector which has the same structure with discriminator to train multiple groups of SAGAN together. The role of the connector is to control the output distribution of the corresponding generator to be consistent with the surrounding generators in order to achieve the purpose of mutual learning. We have conducted experiments on the CODEBRIM dataset and in order to further illustrate the effectiveness of OKD structure, we also applied OKD on ACGAN for experiments. The results show that the performance of some generators has exceeded a single set of SAGAN and ACGAN. Compared with SAGAN, OKD-SAGAN ’s FID score decreases by 15.4% and the average FID score decreases by 5.5%. As for ACGAN, OKD-ACGAN ’s FID score decreases by 7.6% and the average FID score decreases by 3.8%, which proves the validity of OKD structure.","PeriodicalId":354966,"journal":{"name":"Proceedings of the 5th International Conference on Computer Science and Application Engineering","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114314301","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}

Existing works have confirmed that both visual semantic embedding network and cross-modal cross-attention network can achieve similar performance, but the former has lower computational complexity so that its retrieval speed is faster and its engineering application value is higher than the latter. In this paper, we propose a Super Visual Semantic Embedding Network (SVSEN) for cross-modal image-text retrieval, which contains two independent branch substructures including the image embedding network and the text embedding network. In the design of the image embedding network, firstly, a feature extraction network is employed to extract the fine-grained features of the image. Then, we design a graph attention mechanism module with residual link for image semantic enhancement. Finally, the Softmax pooling strategy is used to map the image fine-grained features to a common embedding space. In the design of the text embedding network, we use the pre-trained BERT-base-uncased to extract context-related word vectors, which will be fine-tuned in training. Finally, the fine-grained word vectors are mapped to a common embedding space by a maximum pooling. In the common embedding space, a soft label-based triplet loss function is adopted for cross-modal semantic alignment learning. Through experimental verification on two widely used datasets, namely MS-COCO and Flickr-30K, our proposed SVSEN achieves the best performance. For instance, on Flickr-30K, our SVSEN outperforms image retrieval by 3.91% relatively and text retrieval by 1.96% relatively (R@1).","PeriodicalId":354966,"journal":{"name":"Proceedings of the 5th International Conference on Computer Science and Application Engineering","volume":"50 17","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132974051","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}
