about association rule
by Wu, Haibin (CAP, GE China)
Happy new year.
Well, still got one question in year 2002.
I am just wondering what is the format of input data Apriori accepts:
it should be like which:
AM1078 HB beer
AM1078 Tsingtao beer
AM1078 salad dressing
customer_id product1 product2 product3 product4
product5 product6 product7
AM1101 pen pencil paper tomato . . …
AM1078 tomato cucamber chips HB beer Tsingtao beer salad
or something else.
I did make a try. type2 seems reasonable for association rule in Weka. But I
used some real cases to test it , it didn't give cetain rules.
Anybodu can help?
