How can I force WEKA to find associative rules for a specific attribute only?

[Arash Haydaryan]

Hi, 

In my arff dataset, I have 4 attributes, say, humidity, weather, wind, temperature. How can I find associative rules only for temperature? 

Thanks

Hi Arash, 

You should use Classification Association Rules (CAR) technique. In Weka Explorer, you can use Apriori algorithm in Association panel, by establishing the first option car = True. The second option classIndex allows you to specify the index of your class attribute. Also remember that, for ussing association rules or CAR, your attributes should be categorical...

For theory about CAR, you could read this paper:

Best regards, 

Diana.

Hi Arash,

The easiest way to solve your urgent matter can be:

- Make a copy of you dataset

- Open it in Preprocess

- Click the Invert button

- Unselect those attributes you want for analysis

- Click the Remove button

- Perform the analysis
