Parameters. vector (numpy.array) – Vector from which similarities are to be computed. topn (int or None, optional) – Number of top-N similar words to return, when topn is int. When topn is None, then similarities for all words are returned. The most_similar similar function retrieves the vectors corresponding to "king", "woman" and "man", and normalizes them before computing king - man + woman (source code: use_norm=True). The function call model.similar_by_vector(v) just calls model.most_similar(positive=[v]). monarch healthcare authorization form
