Find the 'rejection matrix' from a semantic vector

"Reject" each word in a word embedding matrix of \(D\) dimension from a vector of \(D\) dimensions, extracted from the same embedding space. The vector can be a single word, or a concept vector obtained from get_centroid(), get_direction(), or get_regions().

Usage

find_rejection(wv, vec)

Arguments

wv

Matrix of word embedding vectors (a.k.a embedding model) with rows as words.

vec

Vector extracted from the embeddings

Value

A new word embedding matrix, each row of which is rejected from vector.

Examples

# \donttest{
data(ft_wv_sample)

vec <- ft_wv_sample["space", ]
rej <- find_rejection(wv = ft_wv_sample, vec = vec)
# }
