Visualize Term Analogies

Visualize analogies for given terms. A visualization of embeddings is two main components from PCA plotted by ggplot on the 2D plane. Additionally, the terms from each given pair are connected to one another. If the embeddings are of good quality, the connection lines should be almost parallel to each other. If find_analogies = TRUE only the pairs with at least one solved analogy task are plotted.

visualize_analogies(term_vectors, terms, find_analogies = FALSE,
  n = 5L, save = FALSE, path_to_save)

Arguments

term_vectors	A matrix of embeddings of terms
terms	A list of two character vectors: the first and the second elements of analogy pairs
find_analogies	A logical indicating if the term analogy task should be performed before the plotting (default: FALSE)
n	An optional number of neighbors included in analogies (default: 5), needed only if find_analogies = TRUE
save	A logical indicating if the plot should be saved to the file
path_to_save	An optional string of the path to the target PDF file

Value

A generated plot of embeddings.
