a$.$ Compute the simple matching coefficient $($SMC$)$ between $P$ and $Q$

discovery. Describe the role of 'data mining and knowledge discovery' in your own words in

those three articles. Provide links to your sources. Make sure that you have a coherent

narrative that combines all three sources.

Question $2(20$ points$)$: Consider the two following boolean strings:

$P=1011110000111010$

$Q=1011000010010001$

a$.$ Compute the simple matching coefficient $($SMC$)$ between $P$ and $Q.$

b$.$ Compute the Jaccard coefficient between the two boolean strings.

Question $3(15$ points$)$: Given a sample of two users and five books from a ratings matrix.

Compute the cosine similarity between User $1$ and User $2$ based on their ratings.

Question $4(20$ points$)$: Consider the two $4-$dimensional points

$p=(4,0,7,4)$

$q=(13,5,9,8)$

$r=(0,2,12,10)$

Compute the pairwise Euclidean distance between p$,$ q$,$ and r$.$ Essentially, you have to

compute the distance between p & q$,$ then q & r$,$ then r & p$.$ Show your work.
