Fixing paper assignments

  1. Please select all papers that belong to the same person.
  2. Indicate below which author they should be assigned to.
Provide a valid ORCID iD here. This will be used to match future papers to this author.
Provide the name of the school or the university where the author has received or will receive their highest degree (e.g., Ph.D. institution for researchers, or current affiliation for students). This will be used to form the new author page ID, if needed.

“诈骗案件分类问题是打击电信网络诈骗犯罪过程中的关键一环,根据不同的诈骗方式、手法等将其分类,通过对不同案件进行有效分类能够便于统计现状,有助于公安部门掌握当前电信网络诈骗案件的分布特点,进而能够对不同类别的诈骗案件作出针对性的预防、监管、制止、侦查等措施。诈骗案件分类属于自然语言处理领域的文本分类任务,传统的基于LSTM和CNN等分类模型能在起到一定的效果,但是由于它们模型结构的参数量的限制,难以达到较为理想的效果。本文基于预训练语言模型Nezha,结合对抗扰动和指数移动平均策略,有助于电信网络诈骗案件分类任务取得更好效果,充分利用电信网络诈骗案件的数据。我们队伍未采用多模型融合的方法,并最终在此次评测任务中排名第三,评测指标分数为0.8625。”
