Combining with the transmission model and sky wave channel model of HF OFDM systems, the channel estimation problem is formulated under the framework of compressed sensing. The block-structured sparsity of channel coefficients in transformed domain of double selective sky wave channel is proved. On this basis, the channel coefficients are reconstructed by structured compressed sensing algorithm. Simulation results show that the proposed structured compression sensing method can significantly reduce the pilot overhead and ensure the accuracy of channel estimation.","PeriodicalId":352285,"journal":{"name":"2020 IEEE 10th International Conference on Electronics Information and Emergency Communication (ICEIEC)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123435165","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}

It may lead to consequences such as program failure or system privileges loss. The mainstream operating systems deploy multiple defense mechanisms to mitigate such attacks. However, so far there are few reports on evaluation of the defense capability of ARM-based operating systems from buffer overflow attacks. In this paper, firstly, we implemented the Runtime Intrusion Prevention Evaluator on ARM-based operating systems, which we called RIPE-ARM. In that evaluator, 850 kinds of effective buffer overflow attacks are integrated for test. Secondly, by using the QEMU virtual machine, an ARM-based system, Raspberry Pi, was set up for the experiment; and then, the RIPE-ARM was used to test and evaluate the defense capability of Raspberry Pi. We identified the kinds of attacks that each defense or defense combination can successfully prevent, respectively. Among all the defense methods, the Canary + DEP combination turns out to be optimal that is able to make 840 out of the total 850 kinds of attacks fail. Furthermore, for comparison, the defense capability of Ubuntu 16.04 LTS system based on X86 architecture was also tested. The results show that the optimal defense method of that system can prevent only 790 attack kinds.","PeriodicalId":352285,"journal":{"name":"2020 IEEE 10th International Conference on Electronics Information and Emergency Communication (ICEIEC)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133701315","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 OpenAI GPT-2 and BERT models are currently widely used language models for text generation and prediction. There have been many experiments to verify the outstanding performance of these two models in the field of text generation.

To address these problems, we propose a combination model of both pre-trained bi-directional long short-term memory (Bi- LSTM) and the conditional random field (CRF) model. Due to the specification of medical texts, we do not employ Chinese word segmentation tools. A character-level feature is introduced as an input feature, which is subsequently mapped into char embeddings by using an embedding layer of the bi-directional encoder representation from transformers (BERT) model. A BiLSTM layer and a CRF are utilized to encode the char embeddings and output the final label. The experiments are conducted with CNMER2019 to evaluate the performance and compared with several previous models.
