指定的隐藏单元＃Facebook中fasttext

Question

在paper on fasttext的监督分类，作者指定的不同数量的隐藏单元通过改变某些参数（h是在3,4页的一个 - 你看在表1中“它有10个隐藏的单位，我们有和没有双字母组对其进行评估。“），但读the documentation后它不会出现有一个‘隐藏单位’参数来改变。有没有办法指定隐藏单位的数量？或者这与指定-dim选项相同？

Answer 1

k是否定的。类

从https://arxiv.org/pdf/1607.01759v3.pdf

第2.1节更准确地说，计算复杂度是O（KH），其中k是类和h的文本表示的维数。

当在文本分类预测类，从docs：

的参数k是可选的，并且是通过默认等于1。 为了获得K中某一段文字，最有可能的标签，使用：

$ ./fasttext预测model.bin的test.txtķ

---

当训练模型，执行与__label__*标签指导训练时，这是隐含在训练数据中指定。
