Python cosine similarity numpy

WebJun 4, 2024 · Solution 1. Iterating in Python can be quite slow. It's always best to "vectorise" and use numpy operations on arrays as much as possible, which pass the work to numpy's low-level implementation, which is fast. cosine_similarity is already vectorised. An ideal solution would therefore simply involve cosine_similarity (A, B) where A and B are ... WebK, so I think I found a way to do this using scipy's cdist function: # for each vector in X, find the most cosine-similar vector in Y def most_similar_i(X,Y): from scipy.spatial.distance import cdist dist = cdist(X,Y,metric='cosine') i = np.argmax(dist,axis=0) # for each vector in X, cdist will store cosine similiarities in a column return i

WebMar 9, 2024 · Jaccard Similarity. Jaccard Similarity is the ratio of common words to total unique words or we can say the intersection of words to the union of words in both the documents. Its scores range between 0–1. 1 represents the higher similarity while 0 represents the no similarity.
