WebJan 19, 2016 · Cosine similarity is part of the cost function used in training word2vec model. The model is reducing the angle between vectors of similar words, so similar words be clustered together in the high dimensional sphere. Typically, for word vectors, cosine similarity > 0.6 means they are similar in meaning. No, cosine similarity between two … WebNov 8, 2024 · Sometimes other proxies of cosine similarity are used. For example, cosine distance is one minus cosine similarity; this ranges over $[0,2]$. Similarly, "half cosine distance" is half the cosine distance, which ranges over $[0,1]$. In the case above, half cosine distance is exactly $\Pr_i[x_i \neq y_i]$. Starting with the actual cosine ...
