Derive the mathematical relationship between cosine similarity and Eu- clidean distance when each data object has an L2 length of 1.
Here, we further explore the cosine and correlation measures.
Let x and y be two vectors where each vector has an L2 length of 1.
For such vectors, the variance is just n times the sum of its squared
attribute values and the correlation between the two vectors is their
dot product divided by n.
