Due to the significantly fewer samples of certain classes in imbalanced datasets, the performance of classifiers may be negatively affected. To solve this problem, we introduce the Local Outlier Factor (LOF) algorithm to remove boundary noise on the basis of the SMOTE algorithm, and use a Gaussian kernel function to consider the similarity of generated samples. We conduct experiments on real intrusion detection data, UNSW-NB15. The results show that LOF-Enhanced SMOTE outperforms SMOTE and Borderline-SMOTE algorithms overall, and significantly outperforms them in detecting certain minority classes. This indicates that the LOF-Enhanced SMOTE algorithm can effectively solve the classification problem of imbalanced datasets.","PeriodicalId":305812,"journal":{"name":"International Conference on Electronic Information Technology","volume":"12719 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129814905","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}

This information, especially the expiration date, needs to be printed correctly before the product is brought to market. Failure to print the correct expiration date can lead to public health problems and recalled products causing financial losses to the company. In this work, we propose an automatic detection and identification of validity areas that can be achieved efficiently and accurately. First, the DBNet network-based approach is applied to detect the expiration date region on food packages. Then the detected expiration date area is intercepted and input to the character recognition network CRNN for character recognition. Finally, the proposed model is deployed on Jetson Xavier NX to implement edge computing of the algorithm, while inference acceleration of the model is performed using TensorRT and FP16 or INT8 quantization. The experimental results show that the method achieves good performance in the detection and identification of expiration dates on different types of food packages, and the method has good real-time and portability.","PeriodicalId":305812,"journal":{"name":"International Conference on Electronic Information Technology","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127921794","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}

Firstly, the fisheye camera is corrected for distortion and perspective transformation, and a weighted fusion algorithm is used to generate partial panoramic images of a single vehicle body. Then, the articulation angle algorithm based on feature point matching is used to obtain the articulation angle information, and the panoramic view image of the entire vehicle is generated by combining the articulation angle information. Finally, a simulation scene is built in Prescan to verify the stitching effect. The simulation results show that the proposed panoramic view system can effectively and clearly generate panoramic view images of semi-trailer trains at different articulation angles, effectively eliminating blind spots in their field of view and improving vehicle safety.","PeriodicalId":305812,"journal":{"name":"International Conference on Electronic Information Technology","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124325338","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}

A search criterion based on the maximum standard deviation is proposed to obtain the optimal pout of FRFT, and then the echo signal is processed by optimal FRFT and inverse Fourier transform. The signal is decomposed into different sub-bands through TQWT for optimizing the wavelet coefficients, and an Ikurt feature selection method is used to extract the wavelet coefficients for reconstruction, so as to achieve the separation of the target from sea clutter. Finally, simulation experiments with measured data from IPIX are carried out to verify the effectiveness of the proposed method.

The open source RISC-V architecture defines a complete set of interrupt mechanisms with hardware definitions that do not support interrupt nesting in embedded systems that only support machine mode, and software support for interrupt nesting adds additional time overhead. This paper is based on the interrupt mechanism defined by RISC-V, using a state machine to control the global interrupt enablement of the processor to support interrupt nesting, and to save the site and restore the site through hardware stacking and out-stacking to avoid the time consumption caused by the software level; a dedicated entry point for interrupt service program jumps further speeds up the response. In this paper, we design and implement a fast interrupt system using Hummingbird E203, an open source kernel defined by standard RISC-V, as an experimental platform. Simulation verification and comprehensive implementation on FPGA platform show that compared to the interrupt handling process of Hummingbird E203, using a small amount of hardware resource consumption, the response speed is improved by 1/4, providing better real-time performance and flexibility in embedded applications.","PeriodicalId":305812,"journal":{"name":"International Conference on Electronic Information Technology","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128759467","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}
