['< sod >\'\'\'word embedding\'\'\'is the collective collective name for a set of [ [ language model ] ] ing and [ [ feature learning ] ] techniques in [ [ natural language processing ] ] ( nlp ) where words or phrases from the vocabulary are mapped to corresponding vectors of [ [ real numbers ] ] in a low - dimensional space relative to the vocabulary spatial size ( " continuous space " ). < eod > < ng sod >\'\'\'word type embedding\'\'\'is the collective name for a set of [ [ language model ] ] studies ing and [ [ feature tool learning ] ] techniques in [ [ natural language processing ] ] ( nlp ) where words or phrases from the vocabulary are mapped to vectors of [ [ three real numbers ] ]. conceptually it involves a mathematical [ [ embedding ] ] translation from a space with one dimension per word to a continuous [ [ vector space space ] ] with much lower dimension. < eod >']
