Parameters of a Weka Classifier

Question

I use Weka. I would like to access the parameters (the weights) of a classifier. What I want to do is to access the values of the parameters to determine how they have an influence on the attributes.

So, my questions are :

• How to access to the parameters of a Classifier ? (with Eclipse)
• How to determine the related attributes of a parameter ?

Answer 1

Here is a related question about weights in WEKA: How to use weights in Weka

And here is an example of java code: http://weka.wikispaces.com/Add+weights+to+dataset

To find out about the relationship between attributes you can use Ranker as a searcher and PrincipalComponents as a evaluator in Selecte attributes tab. And you will get a correlation matrix like this one:

Correlation matrix
  1     -0.11   0.87   0.82 
 -0.11   1     -0.42  -0.36 
  0.87  -0.42   1      0.96 
  0.82  -0.36   0.96   1
