This kind of faulty detection model has achieved a certain degree of detection accuracy, However, most of these prediction models execute prediction based on the current input data [1]. With the development of the modern industrial process, the modern industrial manufacturing equipment is becoming high complexity and large scale. The health situation of the manufacturing equipment is usually associated with not only the current input data, but also the historical data. In this article, the hybrid approach combined with the anomaly clustering and the LSTM is proposed for the faulty classification of the wind turbine. The anomaly analysis is first used to choose the input sensing signal which can well represent the situation of the health situation of the wind turbine, afterwards, the chosen signal input is used as the input of the LSTM data. The result shows that the proposed model performs quite well in the faulty prediction of the wind turbine.","PeriodicalId":246841,"journal":{"name":"2020 3rd International Conference on Advanced Electronic Materials, Computers and Software Engineering (AEMCSE)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121612723","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 solve these problems, this paper introduces the BERT (Bidirectional Encoder Representations from Transformers) pre-training model to enhance the semantic representation of characters, then proposes a novel event subject extraction method combing convolutional neural network (CNN) and long short-term memory (LSTM) to improve the ability of feature learning in the model.

To improve the modelling efficiency, this paper proposes a sketch-image-based automatic 3D modelling method for heel. The images of 2D design sketches are analyzed to determine coordinate information, which is converted into geometric coordinate values usable to create a 3D model of heel. The modelling method uses 3D geometric rules derived from the analysis of strategies adopted by skilled manual operators. It leads to a new process that links the traditional approach with advanced technologies. A case study shows that this method can build the heel model automatically.","PeriodicalId":246841,"journal":{"name":"2020 3rd International Conference on Advanced Electronic Materials, Computers and Software Engineering (AEMCSE)","volume":"224 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131803779","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}

Its main purpose is to extract the opinion element tuple from the user comment data and identify the relationship between them, such as evaluation object, evaluation content, opinion explanation, opinion object. Because the comments of the network having are characterized by randomness, diversity of opinions and different formats, it will become more difficult for the opinion mining task. If we can extract the interrelationships between the various explanatory opinion elements, it not only makes subsequent tasks easier but also applies its extracted results to other related tasks. For example, applying the opinion seven-tuple from the opinion extraction task to the text summary generation task can greatly improve the effectiveness of the text summary generation task. In this paper, we have improved on the traditional LSTM-Attention model and proposed an opinion relationship recognition framework based on improved Target Attention Mechanism. Also, we conducted experiments in two different domains, and the experimental results show that the performance has been effectively improved in two domains.

Firstly, the occluded part of the face is marked by occlusion locator, and then the marked face image is sent to the generator of Generative Adversarial Networks for restoration.
