指定的隱藏單元＃Facebook中fasttext

Question

在paper on fasttext的監督分類，作者指定的不同數量的隱藏單元通過改變某些參數（h是在3,4頁的一個 - 你看在表1中「它有10個隱藏的單位，我們有和沒有雙字母組對其進行評估。「），但讀the documentation後它不會出現有一個‘隱藏單位’參數來改變。有沒有辦法指定隱藏單位的數量？或者這與指定-dim選項相同？

Answer 1

k是否定的。類

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

第2.1節更準確地說，計算複雜度是O（KH），其中k是類和h的文本表示的維數。

當在文本分類預測類，從docs：

的參數k是可選的，並且是通過默認等於1。 爲了獲得K中某一段文字，最有可能的標籤，使用：

$ ./fasttext預測model.bin的test.txtķ

---

當訓練模型，執行與__label__*標籤指導訓練時，這是隱含在訓練數據中指定。
