Construct all association rules $($use frequent k$-$item sets$)$ with support $>4$ and compute confidence for each of them. Show all your work!

$2.[10$ points$]$ Given the following training dataset:

A$1$ A$2$ A$3$ class

$211$ A

$111$ B

$202$ B

Classify the newly coming instance $111?$ using Nearest Neighbor Algorithm, where distance function is Euclidean distance. Assume that the attributes are already normalized. Show all your work!

$3.[10$ points$]$ Given the following dataset:

A$1$ A$2$ A$3$

$034$

$221$

$112$

Normalize each of the attributes $($A$1,$ A$2,$ A$3).$ Write the dataset in normalized attributes. Show all your work!

$4.[15$ points$]$ Given the following dataset:

X Y

$02$

$20$

$32$

$31$

Show how k$-$means algorithm works on this dataset if k $=2$ and the initial seeds are the instances$/$points $(01)$ and $(10).$ Describe the found cluster. Show all your work! Please make sure the answers for each question are included and also written in a way so it's easier for me to put it into a doc
