Exercise $11$: Your task. $($basket$\_$rules$\_$test: $4$ points$).$ Your final task in this notebook is to mine this dataset for pairwise association rules. In particular, your code should produce $($no pun intended!$)$ a final dictionary, basket$\_$rules, that meet these conditions $($read carefully!$)$:

The keys are pairs $($a$,$b$)$

$,$ where a

and b

are item names $($as strings$).$

The values are the corresponding confidence scores, conf$($a$$b$)$

$.$

Only include rules a$$b

where item a

occurs at least MIN$\_$COUNT times and conf$($a$$b$)$

is at least THRESHOLD.

Pay particular attention to Condition $3$: not only do you have to filter by a confidence threshold, but you must exclude rules a$$b

where the item a

does not appear "often enough." There is a code cell below that defines values of MIN$\_$COUNT and THRESHOLD, but your code should work even if we decide to change those values later on$.$
