The vector representations of four vertices are as follows:

Given that the formula to find cosine similarity between two vectors x and y is given by:

calculate the cosine similarity matrix. Set the values of this matrix to be 0 on the diagonal, and discretize the matrix using a threshold value of 0.9. Draw the corresponding unweighted graph. What vertex looks most anomalous in this graph?
