Rcpp_projector-class: Rcpp_projector class

In pommedeterresautee/projector: Project Dense Vectors Representation of Texts on a 2D Plan

Description

Efficient implementation of a function to average embeddings of words from a sentence.

Constructor takes a matrix (embeddings) where each row is a word embedding (each row should have a name, the name being the word related to the embedding) and a logical (na_if_unknwown_word_p) set to TRUE if it is expected to fulfill a row with NA when at the minimum one word of the sentence is unknown, and set to FALSE where it is expected to only average vectors related to known words. If no word are known, the row will always be fulfilled by NA, whatever the parameters are.

Words are defined as letters between separated by one or more spaces in a sentence.

Slots

average_vectors

provide character (texts) and return a matrix of sentence embeddings.

set_unknown_word

change value of parameter na_if_unknwown_word_p (see above).
