"How to see the variable importance of a neural net similar to deep learning?"

annata

Hi everyone

Pls help me. I am working on rapidminer. I am using Deep learning and neutral net to build regression model. In deep learning operator, the output has weight - this port deliver the weight of the attribute with respect to the label attribute, but in neutral net we dont have it. And i want to know how to show the weight of the attribute in neutral net.

tks

Hi @annata,

Unfortunately this operator doesn't support the generation of weights. I would recommend downloading the Interpretation extension, and use Generate Interpretation to generate these weights.

Thanks,

Roland

Hi @RolandJones

Thank you for replying me

I have one more question about neutral net. So , as you know, neutral net use sigmoid for activation function and i wonder that Does rapidminer use this formula for sigmoid: f(A)=1/(1+e^-x)?

hope you will reply

Hi AN,

Yes, I have checked the source code and the function is listed as you describe.

Hi @RolandJones

Thank you for replying me

Can you please check the source code about normalize in neutral net, i want to know how neutral net normalize the input and the way neutral net denormalization in the ouput.
