1.使用Python的split()函数进行标记化 让我们从split()方法开始,因为它是最基本的方法。 在使用指定的分隔符将给定的字符串分隔开之后,它将返回一个字符串列表。 默认情况下,split()在每个空格处中断一个字符串。 我们可以将分隔符更改为任何内容。 让我们来看看。 Word Tokenization text = """Founded in 2002...

Tokenization 指南:字节对编码,WordPiece等方法Python代码详解 在2022年11月OpenAI的ChatGPT发布之后,大型语言模型(llm)变得非常受欢迎。从那时起,这些语言模型的使用得到了爆炸式的发展,这在一定程度上得益于HuggingFace的Transformer库和PyTorch等库。 计算机要处理语言,首先需要将文本转换成数字形式。这个过程由一个称...
一个比较简单的方法解决上述的问题就是我们用Python的字典来标识已有的字符,如下面的代码所示: 1sent_bow ={}2fortokeninsentence_example.split():3sent_bow[token] = 14print(sorted(sent_bow.items())) 通过运行上述的代码,我们可以得到下列的结果,并且可以看出这样子要比矩阵的形式的要简单的多,对于计算的...
