user: I'm refining the data points in my machine learning model and need to compare the similarity of several vector pairs to fine-tune the system. Could you calculate the cosine similarities for the following pairs: [0.5, 0.7, 0.2, 0.9, 0.1] with [0.3, 0.6, 0.2, 0.8, 0.1], [0.2, 0.4, 0.6, 0.8, 1.0] with [1.0, 0.8, 0.6, 0.4, 0.2], and [0.1, 0.2, 0.3, 0.4, 0.5] with [0.5, 0.4, 0.3, 0.2, 0.1]?
