How to know which attribute (or which is the most important) has the most weight in a neural network

Hello,

I need to know which attributes are the most important (the most influence/impact on the model) for a price prediction in a neural network model.

I wondered how we could find this.

Thanks a lot for your help !

You mean Like this ? Just to know, how to be sure it works or in other words how to set-up explain predictions ?

Almost, you do not need to apply the model on an extra data set. In fact, you should provide the original training data of the model to the "tra" port, the model to the "mod" port and a labeled test data set to the "tes" port.

Hope this helps,
Ingo
