Understanding Cosine Similarity Cosine similarity is a metric determining the similarity between two non-zero vectors in a multi-dimensional space. Unlike other similarity measures, such as Euclidean distance, cosine similarity calculates the angle between two vectors rather than their magnitude. ...
Accordingly, the cosine similarity can take on values between -1 and +1. If the vectors point in the exact same direction, the cosine similarity is +1. If the vectors point in opposite directions, the cosine similarity is -1. The cosine similarity is very popular in text analysis. It is...
Calculating image and text cosine similarity CLIP uses "cosine similarity" which is essentially a dot product of the image and text feature vectors. We can just transpose the other tensor and multiply these together with torch: >>> torch.matmul(text_features, i...
