In this article, we propose a method to encrypt the permutation information (PI) and insert the synchronization head based on digital chaos and constellation shaping for orthogonal frequency division multiplexing-free space optical (OFDM-FSO) communication. Probabilistic shaping technology can improve laser emission efficiency, but it will generate the PI, which, transmitted separately, will occup...Show More
Commit messages are critical for code comprehension and software maintenance. Writing a high-quality message requires skill and effort. To support developers and reduce their effort on this task, several approaches have been proposed to automatically generate commit messages. Despite the promising performance reported, we have identified three significant and prevalent threats in these automated a...Show More
Predicting user behavior based on their interactions poses a great challenge in the realm of sequential recommendation. This challenge primarily stems from the erratic and periodic nature of user behavior. Recent approaches leverage attention mechanisms to capture users’ long- and short-term interests by analyzing their past interactions, and have achieved notable improvements of recommendation pe...Show More
We propose an orthogonal frequency division multiplexing - free space optical - chaotic constellation shaping (OFDM-FSO-CCS) scheme based on synchronization header assistance. The redundant information of constellation shaping is converted into a binary bit stream. The bit stream is encrypted by using a pseudo-random binary sequence (PRBS) generated by the 1-dimensional chaotic map amplifier (1-DC...Show More
In environments with limited information, intelligent agents have restricted access to their current location, target location, and local environment details. To enhance their perception capabilities, this study introduces a fusion model called GraphSAGE-DH-Bug, which combines GraphSAGE and DH Bug algorithms. More importantly, the article presents the process of generating expert training database...Show More
