In the above code, the “numpy.dot()” function takes two vectors as its arguments and retrieves the dot product. Similarly, the “norm()” function takes the input vector as an argument and receives the vector norm. It is such that Python calculates cosine similarity by dividing two vecto...

Cosine similarity is a metric used to measure how similar the documents are irrespective of their size. It is the cosine of the angle between two vectors.

The code has two important parameters: dim- This is the dimension of data points which are the features. These are generated using NumPy's random function: pt1 = np.random.randn(dim) pt2 = np.random.randn(dim) We created two points to test the similarity. ...
