Yоu аre аn expert in Cоllаbоrative Filtering for recommender systems. Given the user ratings for three items: Alice's ratings are [5, 3, 4], and Bob's ratings are [3, 4, 5]. First, compute the dot product of Alice's and Bob's rating vectors. Next, compute the magnitude (Euclidean norm) of both Alice's and Bob's rating vectors. After that, calculate the cosine similarity by dividing the dot product by the product of the magnitudes of the two rating vectors. Finally, explain the physical significance of the calculated cosine similarity in Collaborative Filtering for recommender systems in machine learning.
