Thus, the beamforming method of FDA should take interference in range-angle dimension into consideration, which will produce higher complexity than phased array and unstable beampattern. In this paper, based on Minimum Mean Square Error (MMSE) criterion， a robust adaptive beamforming method of FDA with sidelobe canceller technique is proposed. Compared with method based Maximum Signal Noise Ratio (MSNR) criterion, the proposed method shows better stability and similar two-dimensional anti-jamming performance to MSNR criterion. Simulations indicate the feasibility and validity of the method.","PeriodicalId":305812,"journal":{"name":"International Conference on Electronic Information Technology","volume":"198 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":"122529546","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}

At present, most of the models are trained based on character vector and word vector. Compared with traditional models, this method can fully consider the long and irregular language characteristics of daily chit-chat dialogues, and make full use of character and word fusion to improve the dialogue performance of the model. At the same time, the word embedding matrix trained by the pre-trained model is calculated to obtain the same dimension as the character embedding. Then, the character vector and word vector are fused, and the transformer model is used for dialogue training.

In order to solve the above problems, this paper proposes a two-stage Chinese text summarization generation method based on Transformer and temporal convolutional network. The first stage uses a summary generation model that fuses Transformer and a temporal convolutional network, and generates multiple candidate summaries through beam search at the decoding end. In the second stage, contrastive learning is introduced, and the candidate summaries are sorted and scored using the Roberta model to select the final summary. Through experiments on the Chinese short text summarization dataset LCSTS, ROUGE was used as the evaluation method to verify the effectiveness of the proposed method on Chinese text summarization.","PeriodicalId":305812,"journal":{"name":"International Conference on Electronic Information Technology","volume":"37 9 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":"132436926","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}

At present, the research on status estimation of primary equipment in the substation is mature, but there is still no unified evaluation standard and diagnostic process for secondary equipment. Therefore, an improved fuzzy algorithm model based on variable weight theory and membership correction is proposed to estimate the status of secondary equipment in the substation. The example analysis verifies that the improved fuzzy algorithm can improve the accuracy of state estimation and effectively avoid a series of problems caused by constant weights and fixed membership of the traditional fuzzy algorithm. The light transmission power decreases from -14.68 dBm to -19.74 dBm, while the temperature decreases from 23 °C to 28 °C. The health status of both indicators decreased by a level consistent with the observations.","PeriodicalId":305812,"journal":{"name":"International Conference on Electronic Information Technology","volume":"111 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":"134514570","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}

Conductive yarn, as the most basic flexible conductive textile material, the conductive yarn is widely used in intelligent wearable products. However, traditional textile materials are usually insulating materials and do not directly form conductive yarns and smart wearable products. This paper focuses on the preparation methods of conductive yarns by coating, spinning, and in situ polymerization, and the application research progress in wearable strain sensors, wearable supercapacitors and wearable electric heating devices. In addition, the convenience, comfort, washability and sensitivity required for wearable electronics are proposed to further optimise the flexible sensitivity and durability of conductive yarns and methods of combining textile materials with conductive materials are the main development directions for wearable flexible smart products.","PeriodicalId":305812,"journal":{"name":"International Conference on Electronic Information Technology","volume":"53 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":"123863775","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 two proposed algorithms formulate the joint design of MMSE transceiver as a non-convex, multi-variable coupled optimization problem under power constraint. This problem is modeled using the Lagrange multiplier method, and the analytical solution is obtained by continuously updating the gradient through a generalized iterative method. This method achieves a specific design of subband-level precoding matrix that balances performance, computational complexity and feedback overhead. Additionally, this paper proposes the implementations of the above algorithms in terms of neural network structures. The deep learning-based precoding algorithm significantly reduces computation complexity compared to the traditional iterative algorithms. Furthermore, the robustness of our proposed implementation can be greatly improved by adjusting the network structure and training dataset, and its performance gain can be comparable to or even better than those of the iterative algorithms. Finally, the link simulations are performed to verify the performance gains of our algorithms.","PeriodicalId":305812,"journal":{"name":"International Conference on Electronic Information Technology","volume":"20 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":"116665271","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}
