Sir,

I am new in Association rule mining. When I extract the rules using demoassocationanalysis.m function and the get following rules.

Rule (Support, Confidence)

alltimelow -> food,low (20%, 71.4286%)

low -> alltimelow,food (20%, 100%)

alltimelow,food -> low (20%, 83.3333%)

alltimelow,low -> food (20%, 100%)

I think all the above rules are almost same. How to remove the duplicate rules and get the best rule without repetition.

Thank you.
