- 3. Q1. Solve the Apriori example using the above data ? Given sup count=2. TID ITEMS BOUGHT 1 Potato, burger, milk 2 Milk , beer 3 Onion , potato , milk 4 Onion , potato , burger , beer 5 Onion , potato ,burger , milk 6 Onion , potato , milk
- 4. STEP 1: get given data as it is. TID ITEMS BOUGHT 1 Potato , burger ,milk 2 Milk , beer 3 Onion ,potato , milk 4 Onion, potato , burger , beer 5 Onion , potato , burger , milk 6 Onion , potato , milk
- 5. Step 2: take the support count of each item ITEMS BOUGHT SUPPORT Potato 5 Burger 3 Milk 5 Beer 2 Onion 4
- 6. Step 3: find and remove below value of sup count Item bought support potato 5 burger 3 milk 5 beer 2 onion 4 Item bought support potato 5 burger 3 milk 5 beer 2 onion 4 Here not remove any item because of not any item is less than sup count
- 7. Step 4 : combine items & remove the less sup count from support. Items Bought support Potato, burger 4 Potato, milk 4 Potato , beer 1 Potato , onion 4 Burger , milk 2 Burger , beer 1 Burger , onion 2 Milk , beer 1 Milk , onion 3 Beer , onion 1 Items support Bought Potato ,burger 4 Potato,milk 4 Potato , onion 4 Burger , milk 2 Burger ,onion 2 Milk , onion 3 Remove the less than 2 because sup count=2
- 8. Step 5: combine the items Items Bought support Potato, burger 4 Potato , milk 4 Potato , onion 4 Burger , milk 2 Burger , onion 2 Milk , onion 3 Combine items & calculatethe supportcount Items Bought Support Potato , burger , milk 2 Potato , burger , onion 2 Potato , milk , onion 3 Burger , milk , onion 1
- 9. Step 6: find big support count & get final output Items Bought Support Potato , burger , milk 2 Potato , burger , onion 2 Potato , milk , onion 3 Burger , milk , onion 1 largest count Items Bought Support Potato , milk , onion 3 Getfinal outputthatissupportcount= 3
