WebFeb 28, 2024 · cosine_similarity指的是余弦相似度，是一种常用的相似度计算方法。它衡量两个向量之间的相似程度，取值范围在-1到1之间。当两个向量的cosine_similarity值越接近1时，表示它们越相似，越接近-1时表示它们越不相似，等于0时表示它们无关。 WebThere are a few common problems and solutions when using the CosineSimilarity function in PyTorch. One such problem is that, due to floating point precision, the cosine similarity between two tensors can sometimes be slightly greater than 1.0 . To resolve this, you can use the torch.clamp() function to limit the value to 1.0. food galore
