E-commerce website (ECW) have become an important bridge for daily communication between enterprises and between enterprises and consumers. Image is one of the most important and commonly used information of human beings; Digital IPT is the process of converting image signal into digital format and processing it by computer. This paper studies and analyzes the application of graphics and IPT in the construction of ECW, discusses the graphics and IPT and the result design process of ECW, and tests the network name's views on the website construction proposed in this paper through online questionnaire experiment. The results show that 84% of Internet users using graphics and IPT in the construction of ECWs will make people more willing to browse websites, and 76% said that the visual effect of web pages is good, while websites without graphics and IPT have little effect on improving shopping desire, and only 61% of Internet users said they are willing to browse websites. It is verified that the application of graphics and IPT in the construction of ECW in this paper is conducive to improve the browsing volume of the website, and can also improve the visual aesthetic sense for Internet users, which is welcomed by the audience.","PeriodicalId":196224,"journal":{"name":"Proceedings of the 6th International Conference on Graphics and Signal Processing","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116858251","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}

{"title":"Classification of Vulnerable Road Users based on Range-Doppler Maps of 77 GHz MIMO Radar using Different Machine Learning Approaches","authors":"F. Bayram, Florian Pütz, Julian Weiß, R. Radtke, Alexander Jesser, N. Stache","doi":"10.1145/3561518.3561523","DOIUrl":"https://doi.org/10.1145/3561518.3561523","url":null,"abstract":"This paper involves the development of an intelligent delineator for road traffic detecting potential conflict situations between motor vehicles and vulnerable road users at an early stage. By emitting warning signals, collisions between the road users concerned can then be prevented. The prototype used here includes, among other sensors, a high-resolution FMCW radar capable of detecting, and imaging objects. The goal of this work is to develop a Machine Learning (ML) model for object classification of vulnerable road users in radar frames. A 77 GHz chirp-sequence radar is used to record Range-Doppler maps from object classes of car, bicyclist, pedestrian and empty street at different locations. Objective of this is to cover different levels of background noise in the data caused by the different environments due to trees or bushes. For the data acquisition, simple traffic scenarios have been simulated at Heilbronn University. In selecting a suitable ML algorithm for the classifier, the main challenge was that modern machine learning methods are data-based models which require a lot of data and are generally lacking in explainability, such as neural networks. However, the great advantage is that the correlations in the data are learned automatically. With knowledge-based methods, on the other hand, the big advantage is that they are explainable and require much less data, but assume an extensive domain knowledge. Hybrid learning, also called Informed ML, represents a combination of the methods previously mentioned and their advantages. In this paper, one approach from each of these methods is selected as well as trained, and its results are compared to each other. The respective approaches investigated are a deep neural network (DNN), a Support Vector Machine (SVM), and a hybrid model of a SVM and a specific neural network for feature extraction called Autoencoder (AE). In this comparison the SVM performs with prediction accuracies around 80%. The hybrid model performs better achieving prediction accuracies around 90%. The best results of this comparator are achieved by the DNN, which has a prediction accuracy of around 98%.","PeriodicalId":196224,"journal":{"name":"Proceedings of the 6th International Conference on Graphics and Signal Processing","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124576777","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 delineation of biodiversity protection and ecological protection red lines has a high degree of strategic fit, goal synergy and spatial consistency. Based on multi-source satellite data, this paper uses 3S technology as a means to construct a remote sensing biodiversity conservation function index, and conduct remote sensing monitoring and evaluation of the biodiversity conservation function of the ecological protection red line of Ruoergai wetland from 2000 to 2019. The protection of ecological protection red lines plays an important guiding role. The results show that: in terms of time, the area of the region with poor and poor biodiversity conservation function levels continues to shrink, and the area of the region above good continues to increase., the 20-year average biodiversity conservation function index evaluation grades accounted for 0.4% excellent, 18.2% good, 77.2% general, 3.9% poor, and 0.3% worst, mainly general and good, accounting for 95.4%, the grades of poor and worst are mainly distributed in the southeastern and northern parts of the red line area. In the past 20 years, the functional quality of biodiversity in the red line area of the Ruoergai Wetland has been maintained in a relatively good state, and the improvement in the northwest is more obvious than that in the southeast.","PeriodicalId":196224,"journal":{"name":"Proceedings of the 6th International Conference on Graphics and Signal Processing","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121905966","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}

There has been a great deal of research in this area. In order to understand linguistic representations and their applications in various domains of analysis, various factors such as demographics, emotions, and gender are taken into account in a transactional context. In this paper, we focus on those factors that can be extracted from existing data using natural language processing. We find that the most successful personality trait prediction models rely heavily on NLP techniques. To automate this process, researchers around the world have used a variety of machine learning and deep learning techniques. Different combinations of factors have led to different research results. We have conducted a comparative analysis of these experiments in the hope of determining the future course of action.","PeriodicalId":196224,"journal":{"name":"Proceedings of the 6th International Conference on Graphics and Signal Processing","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122363079","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 BERT-IDCNN-CRF model. In this model, the two-way transformer pre training model BERT is used to fine tune the model parameters in the manual annotated corpus conforming to the BIOES (Begin Inside Outside End Single) standard. The text is learned in an unsupervised manner, and the semantic information of words is represented by word vectors, which can well represent the context semantics in the sentences of EMRS; The state characteristics of character sequences are learned through BERT model, and the sequence state scores obtained are input to the CRF layer. The CRF layer makes constraint optimization on the sequence state transition, and IDCNN has better recognition effect on convolutional coding of local entities. Experimental test results: the average accuracy, recall and F1 value of the BERT-IDCNN-CRF model are 94.5%, 93.8% and 94.1% respectively, which are increased by 4.8%, 4.3% and 3.6% respectively compared with the baseline model Word2Vec-BiLSTM-CRF. The experiment proves that the BERT-IDCNN-CRF model can better identify medical entities in electronic medical records.","PeriodicalId":196224,"journal":{"name":"Proceedings of the 6th International Conference on Graphics and Signal Processing","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133048307","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}

We also find that the nasalance score of the nasal initials with different places of articulation is affected differently by the subsequent vowel: for the nasal initials in the front, that is, for the bilabial nasals and dental nasals, the higher the position of the tongue of the following vowel, the higher the nasalance score of the nasal; for the nasal initials at the back, namely for the alveolar- palatal nasals and velar nasals, the more forward the position of the following vowel, the higher the nasalance score of the nasal.

With the development of technology, many methods of facial expression recognition have been proposed. However, from traditional methods to deep learning methods, few of them pay attention to the hybrid data augmentation, which can help improve the robustness of models. Therefore, a method of hybrid data augmentation is highlighted in this paper. The hybrid data augmentation is a method of combining several effective data augmentation. In the experiments, the technique is applied on four basic networks and the results are compared to the baseline models. After applying this technique, the results show that four benchmark models have higher performance than those previously. This approach is simple and robust in terms of data augmentation, which makes it applicated in the real world in the future. Besides the results show versatility of the technique as all of our experiments get better results.","PeriodicalId":196224,"journal":{"name":"Proceedings of the 6th International Conference on Graphics and Signal Processing","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122233835","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}
