Abstract In recent years, with the rapid development of natural language
processing, the security issues related to it have attracted more and more
attention. Character perturbation is a common security problem. It can try to
completely modify the input classification judgment of the target program
without people’s attention by adding, deleting, or replacing several characters,
which can reduce the effectiveness of the classifier. Although the current
research has provided various methods of perturbation attacks on characters, the
success rate of some methods is still not ideal. This paper mainly studies the
sample generation of optimal perturbation characters and proposes a characterlevel… More >
