tf.keras.preprocessing.text.one_hot

One-hot encodes a text into a list of word indexes of size n.

tf.keras.preprocessing.text.one_hot(
    input_text,
    n,
    filters='!"#$%&()*+,-./:;<=>?@[\\]^_`{|}~\t\n',
    lower=True,
    split=' '
)

This function receives as input a string of text and returns a list of encoded integers each corresponding to a word (or token) in the given input string.

input_text Input text (string).
n int. Size of vocabulary.
filters list (or concatenation) of characters to filter out, such as punctuation. Default: '!"#$%&()*+,-./:;<=>?@[\]^_`{|}~\t\n, includes basic punctuation, tabs, and newlines.
lower boolean. Whether to set the text to lowercase.
split str. Separator for word splitting.

List of integers in [1, n]. Each integer encodes a word (unicity non-guaranteed).
