In response to this problem, this paper proposes a movie rating prediction recommendation algorithm based on XGBoost-DNN. First, XG-Boost is used to screen user features and movie features, and the features that have a great impact on movie rating prediction are screened out, and then the screened features are used as the input of DNN, the user network, and the movie network is trained to obtain the user feature vector and movie feature vector respectively, and then the user's predicted rating of the movie is obtained through the neural network, and finally compared with LightGBM, SVR, KNN, and RandomForest, this paper proposed XGBoost-DNN model reduces the MSE indicator by 0.223, 0.75, 0.451, and 0.306 respectively, which effectively improves the accuracy of rating prediction, and thus improves the accuracy of movie recommendation.","PeriodicalId":211213,"journal":{"name":"2022 12th International Conference on Information Science and Technology (ICIST)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116176811","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 named entity recognition will directly affect the performance of event argument role recognition, which results in error propagation. Meanwhile, treating the event extraction task as a classification task ignores semantic information in sentences. In the paper, we propose a dual machine reading comprehension model (Dual-MRC) for event extraction, which converts the classification task into a span extraction task. The model consists of the part of speech of the candidate argument on the left and the imperative sentence on the right to form a question template, dramatically improving the ability of event extraction. Dual-MRC achieves an F1 value of 74.6% in the event trigger extraction and classification task.Our model performs excellently in the case of data-low scenarios, demonstrating the advantages of machine reading comprehension. Experimental results show that our method is effective on the ACE 2005 dataset, especially for multi-word trigger extraction. In addition, we publish a Chinese mine accident annotation dataset. To the best of our knowledge, this is the first Chinese mine accident event dataset, and we verify the performance of the model in Chinese event extraction on this dataset.","PeriodicalId":211213,"journal":{"name":"2022 12th International Conference on Information Science and Technology (ICIST)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124012720","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}

Once it occurs, it will cause severe damage to the ecological environment. Synthetic Aperture Radar (SAR) is widely used in marine oil spill monitoring due to its all-weather and all-day characteristics. However, the contrast of different SAR images is inconsistent, making it difficult for the network to learn valuable features. To address this issue, this paper proposes an improved YOLOX-S (IYOLOX-S) model for marine oil spill detection. The model enhances image contrast by a truncated linear stretch module, uses CspDarknet and PANnet to extract image features, and obtains oil spill detection results through Decoupled Head. First, a truncated linear stretching module is added, which can improve the image contrast. It also highlights the characteristics of oil spill areas to enhance the networks learning ability. Second, the proposed score loss into the global loss function enhances the learning ability of the model and improves the detection accuracy. Experiments are carried out on the collected oil spill dataset, and the test sets average precision (AP) is 90.02%. The experimental results show that the improved YOLOX-S model accurately identifies oil spill areas.","PeriodicalId":211213,"journal":{"name":"2022 12th International Conference on Information Science and Technology (ICIST)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116385377","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}

Since it is difficult to achieve collaborative defense against existing resources and strategies of multiple autonomous systems, this paper designs and organizes them into autonomous system community. Within the community, a precomputing multi-link generation mechanism is proposed based on genetic algorithm. Before the inter domain routing system is attacked, the link set can be generated as complete as possible in advance. Once an attack occurs, the community will quickly select proper precomputing links to replace the failed ones, in order to ensure the stability of inter domain communication.

However, the requirement of numerous projections collected in a full-angular range hinders CT image-guided applications such as real-time biopsy. This paper mainly discusses the most challenging single view CT reconstruction problem to speed up the CT-guided clinical workflow. We propose a deep learning approach for single-view CT reconstruction guided by Filtered Back Projection (FBP) algorithm which makes the single view reconstruction accurate, fast and interpretable. We formulate an end-to-end framework that contains the projection generation network to predict sufficient projections from a single view, the FBP layer to obtain coarse CT volume, and the CT fine-tuning network to output the final CT volume. We carefully design our training strategy to ensure the network towards CT reconstruction. Our experiments on the public 4D CT datasets prove that our method achieves state-of-the-art performance.","PeriodicalId":211213,"journal":{"name":"2022 12th International Conference on Information Science and Technology (ICIST)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131499747","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}
