Distributed Denial of Service (DDoS) is a predominant threat to the availability online services due their size and frequency. However, developing an effective security mechanism protect network from this big challenge because DDoS uses various attack approaches coupled with several possible combinations. Furthermore, most existing deep learning- (DL-) based models pose high processing overhead or may not perform well detect recently reported attacks as these use outdated datasets for...

Code clone detection aims to find similar code fragments and gains increasing importance in the field of software engineering. There are several types techniques for detecting clones. Text-based or token-based detectors scalable efficient but lack consideration syntax, thus resulting poor performance syntactic Although some tree-based methods have been proposed detect semantic clones with decent performance, they mostly time-consuming scalability. In addition, these can not realize...
