在此NLP教程中讨论的所有步骤都只是文本预处理。在以后的文章中,将会使用Python NLTK来实现文本分析。 我已经尽量使文章通俗易懂。希望能对你有所帮助。 (function(){ function setArticleH(btnReadmore,posi){ var winH = $(window).height(); var articleBox = $("div.article_content"); var artH = ...

摘要:在这篇文章里我们提出了 CodeRetriever,通过大规模的代码-文本对比预训练,来学习函数级 (Function-Level) 的代码语义表示。在 CodeRetriever 中,我们提出了两种对比学习的策略:单模态和双模态的对比学习。对于单模态的对比学习 (code-to-code),我们提出了一种无监督的方式,根据代码中的自然语言信息,来构建具有...
