WebSep 10, 2024 · Hey so the Keras implementation of Cosine Similarity is called as Cosine Proximity. It just has one small change, that being cosine proximity = -1* (Cosine Similarity) of the two vectors. This is done to keep in line with loss functions being minimized in Gradient Descent. WebAug 31, 2024 · The forward () method returns the cosine similarity (or it will once I write it) between two embeddings. If calc_cos_sims () is copied to each process, would I need to replace the mp.spawn () line with all_cos_sims = mp.spawn () in order to store the results from all the GPUs? Thanks in advance for your help!
