Rule extraction form neural networks

Question

Hi everybody,

did anyone of you make experiences in terms of extracting rules from  neural networks by using rapid miner?
The goal is to make the output of neural networks being compared to decision trees more accurate more comprehensible for humans.

Thank you.

Hi Christian,
in general there are existing two ways of adding CART to RapidMiner: Do it yourself or let it do someone else.
But telling you how to write extensions for RapidMiner could fill books. In fact, it does fill a book, which is (surprisingly) available in our shop. It gives you an introduction how to extend RapidMiner, which are the most important data structures and classes and how they work.
If you don't feel familiar enough with Java programming to do it yourself, or you can't expend the time it would take, you always could ask us for a quote for a certain extension.

Hi Sebastian,

Thanks for your reply.
But maybe you could give me an hint how to add CART functionality to RM in general?

Hi,
you could of course discretize the label. Take a look at the various discretization operators. What's reasonable depends on your task and unless you want us to do consulting for you, we are not familiar with your problem.
And of course there are various ways of adding CART functionality to RapidMiner...
