Scholars have applied it to different scenarios such as 3D object detection, object tracking, pose estimation and so on. The core of this method is to detect and match corner points. Although a considerable number of papers have been studied on this issue, there are still a lot of missed detection and false detection. In this paper, we pro-posed a one-stage object detection method with confine key- point triplets(ConfineNet), which applies center pooling and corner matching limit in local feature region. This restrictions can provide stronger correlation features with the object for subsequent prediction of center points, which can help to improve the prediction results of center points and corner matching. In addition, ConfineNet learns the association distance between the upper-left corner point and the lower-right corner point, which can confine the corner matching within a local area, thereby reducing matching errors. The AP value of Confine- Net reaches 48.2% on MS-COCO test-dev. our ConfineNet not only outperforms all existing anchor-free detectors but also achieves comparable performance to the state-of-the-art of two-stage detection approaches.","PeriodicalId":412698,"journal":{"name":"2021 IEEE International Conference on Artificial Intelligence and Industrial Design (AIID)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121523000","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}

Our method can efficiently analyze attributes of different dimensions to make predictions better. We evaluated our XGboost trading behavior on the Jane Street dataset provided by the kaggle competition.

It has important applications in military and civil occasions. Traditionally, expert-experience is used for feature extraction, which is time-consuming and unstable. In order to overcome this shortcoming, this paper proposes an Intelligent Radiometric Identification algorithm base on Time and Frequency domain feature Fusion (IRI-TFF) which uses deep learning technology. The algorithm designs a new multi-domain fused one-dimensional complex-valued densely connected convolutional network (DenseNet) model after the accurate “calibration” preprocessing of the received signal and the combination of time and frequency domain data as training examples. Meanwhile, three fusion strategies are proposed. The experimental results show that the proposed algorithm is superior to the traditional expert-experience based SEI algorithm or other similar deep learning based SEI algorithm, and is robust to noises.","PeriodicalId":412698,"journal":{"name":"2021 IEEE International Conference on Artificial Intelligence and Industrial Design (AIID)","volume":"194 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131886142","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}

Due to the fact that there are more artificial experience thresholds, some shortcomings such as low detection accuracy, poor robustness, and inability to systematically deploy on a large scale, which lack of insufficient intelligence. Therefore, we proposed a book information extraction algorithm based on object detection and optical character recognition (OCR) that is suitable for multiple book information recognition, multiple book image angles and multiple book postures. It can be applied to scenes such as book sorting, bookshelf management and book retrieval.
