Hi Mark,

I am Perry. I was impressed with Mark's marksmanship in Weka. As such I would like to share and seek advice to my Data Mining headache with my fellow forum members specially Mark. I do not know if my question is to simple or to complicated.

Objective: Predict the likelyhood of a Leads to respond with given marketing campaign. My Class is simply YES or NO. The outcome of my historical data.

My Solution: I've developed model in Explorer using the following algorithm J48, LMT, and MultiPerceptron.

Question:

1) Have I used the most appropriate models for the Objective?

2) I used Explorer in developing the model, based on most Forum Thread in Pentaho they are using Experimenter. I do not have any idea with Experimenter.

- What is Experimenter in a nutshell anyway?

- What I am missing if I use do not use Experimenter?

- Could you give me a link where I could start learning Experimenter and its concepts.

3) My Historical Dataset for training the model has imbalance Class. Lets say 90% responded NO to marketing, 10% responded YES. How do I improve the accuracy of my model.

P.S. I will greatly appreciate any advice to be given on my headache. In advance thank you very much.
