1. Basic association rule creation manually.

The 'database' below has four transactions. What association rules can be found in this

set, if the minimum support (i.e. coverage) is 60% and the minimum confidence (i.e.

accuracy) is 80%?

Trans_id Itemlist

T1 {K, A, D, B}

T2 {D, A C, E, B}

T3 {C, A, B, E)

T4 {B, A, D}

Show each step of your calculation in details (i.e. item sets containing one item, two

items like this), as each step will be graded individually.
