The sparse autoencoder with outstanding learning ability is used to learn a dictionary witch has better feature expression ability in the stage of dictionary learning. For the improvement of autoencoder, the mean absolute error principle is taken as the reconstruction error term to improve the accuracy of model error measurement. In the stage of data preprocessing, the whitening technology is used to construct the low redundancy input data to improve the generalization ability of sparse autoencoder dictionary learning model. In the stage of image reconstruction, the dictionary obtained is applied to the super-resolution algorithm based on anchored neighborhood regression to achieve fast real-time reconstruction by reducing the computation of sparse coding. In this study, the proposed super-resolution algorithm combines the advantages of sparse autoencoder model and anchored neighborhood regression, which can not only improve the quality of image reconstruction, but also guarantee the reconstruction speed at the same time. So it has high reconstruction efficiency.","PeriodicalId":403102,"journal":{"name":"2021 International Symposium on Computer Technology and Information Science (ISCTIS)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130490715","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 improve the overall work efficiency, the UAV oblique photography is used in the 3D modeling. It not only liberates technicians from the hard field work, greatly reduces the field work workload, but also can quickly build 3D real-scene model, shorten the drawing period, reduce the production cost, which has a positive role in promoting the development of geographic information industry. However, in the process of UAV tilt photography, the image effect is often not very ideal due to the influence of bad weather such as uncertain rain or shine and wind and fog, and uneven illumination phenomena such as underexposure, overexposure and shadow appear, which directly affect the quality of the 3D real-scene model in the later stage. In order to eliminate this effect, Retinex method in image enhancement technology is applied to preprocess the oblique photography image to ensure the image quality, which lays a foundation for the quality of the subsequent 3D real-scene model.","PeriodicalId":403102,"journal":{"name":"2021 International Symposium on Computer Technology and Information Science (ISCTIS)","volume":"68 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120893535","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, recommendation with social networks faces two challenging problems, and has not been well-studied in most existing works. The first is cognitive differences. Even users with similar preferences face the same recommended objects, they will make different choices due to cognitive differences. Therefore, modeling the cognitive similarity of users is crucial. The second is the influence strength of her friends might be different. To solve the above problems, this paper proposes a new deep learning model called MCSRec. Specifically, based on users' long short- term personal preferences, design a memory cognitive module to model the cognitive similarity between users and their friends. Then, after obtaining friends' preferences which are similar to users' cognition, model social influence with a graph attention network. The experimental results on three public data sets prove the effectiveness of our proposed MCSRec model on several competitive baselines, including state-of-the-art models.","PeriodicalId":403102,"journal":{"name":"2021 International Symposium on Computer Technology and Information Science (ISCTIS)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123848035","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}
