How do we compare models using MS Data Mining Tools?
So say I have three classification models: using Decision Tree, Logistic Regression & Neural Networks - How Do I compare the models to see which one performs the best for my data?
Thanks.

Microsoft Data Mining Tools can show gain chart(it is called lift chart in the product), profit chart and classification matrix.

Hi Paras,
Choosing the best algorithm to use for a specific analytical task can be a challenge. I would recommend you refer to the following article to choose the right algorithm, please see:

Hello,
you need to ensure you create the models within the same mining structure and then you can compare the models using the 'Mining Accuracy Chart' tab. You will need to research into interpreting the results if they dont mean anything to you.
Kind regards,
Shaheen

Great point about choosing a best algorithm for an analytical task is a challenge. My questions was more about the next step where I wanted to know once I've created the models - then how do I compare them. I got my answer via other replies.
