set_vocabulary: Sets vocabulary (and optionally document frequency) data for...

In dfalbel/keras: R Interface to 'Keras'

Description

This method sets the vocabulary and DF data for this layer directly, instead of analyzing a dataset through adapt(). It should be used whenever the vocab (and optionally document frequency) information is already known. If vocabulary data is already present in the layer, this method will either replace it, if append is set to FALSE, or append to it (if 'append' is set to TRUE)

Usage

set_vocabulary(object, vocab, df_data = NULL, oov_df_value = FALSE,
  append = FALSE)

Arguments

object	a text vectorization layer
vocab	An array of string tokens.
df_data	An array of document frequency data. Only necessary if the layer output_mode is "tfidf".
oov_df_value	The document frequency of the OOV token. Only necessary if output_mode is "tfidf". OOV data is optional when appending additional data in "tfidf" mode; if an OOV value is supplied it will overwrite the existing OOV value.
append	Whether to overwrite or append any existing vocabulary data.
