###### Develop an activity that aligns to the chosen strategy you identified in Step 3 that Mark could do at home. In 250-500 words, describe the activity, as well as how you would establish and maintain a collaborative relationship with Mark’s parents and encourage them to help implement it

{ b, d, e }
{ c, d}
{ a, b, e }
{ a, d, e }
{ a, b, e }

Compute the support for items{e}, {b, d} and {b, d, e} by treating each transaction ID as a market basket
{e}: support → 8/10 = 80%
{b,d}: support → 2/10 = 20%
{b,d,e}: support → 2/5 = 20%
Use the results in part (a) to compute the confidence for the association rules
{ b, d}→ {e} and {e}→{b, d}. Is confidence a symmetric measure?
{b,d} → {e}: confidence → 2/2 = 100%

● {e} →{b,d}: confidence → 2/8 = 25%

Confidence is not a symmetric measurement.
Repeat part (a) by treating each customer ID as a market basket. Each item should be treated as a binary variable (1 if an item appears in at least one transaction bought by the customer, and 0 otherwise.)
{e}: support → 4/5 = 80%.

● {b,d}: support → 5/5 = 100%

● {b,d,e}: support → 4/5 = 80%
For each of the following measures, determine whether it is monotone, anti-monotone, or non-monotone ( i.e neither monotone nor anti-monotone).
Support, s = ( δ(X))/(∣T∣) is anti-monotone because s(X) ≥ s(Y) whenever X c Y (3 points)

A characteristic rule is the rule of the form {p}→{q1, q2, ……qn }, where the rule antecedent contains only a single item. An itemset of size k can produce up to k characteristic rules. Let ζ be the minimum confidence of all characteristic rules generated from a given itemset:
ζ ({p1, p2, ……pk}) = min [ c({p1 }→ {p2, p3 ……….pk}……
c({pk }→ {p1, p3 ……….pk-1}]
Is ζ monotone, anti-monotone or non-monotone ?

From the following table itemsets, answer the subsequent questions. (6 points)

What is the maximum number of association rules that can be extracted from this data (including rules that have zero support)?
What is the maximum size of frequent itemsets that can be extracted (assuming
Min-sup > o)?
Find an itemset (of size 2 or larger) that has the larger support.
