I want to minimize a mean squared weighted deviation in a neural network. The weights are different for each sample.
How can I specify this?
Is it perform(net,t,y,ew)?
ew = [a b c d ...] (weight for each sample)

The documentation commands
help train
doc train
yield
[NET,TR] = train(NET,X,T,Xi,Ai,EW)
Hope this helps.

Yes.
However, I would scale the data so that the maximum weight is unity.
Hope this helps.
Thank you for formally accepting my answer

Hi Greg,
When I do perform(net,t,y,ew), the training process does not consider the weights. How can I include the weights in the training?
If I scale the weights (wide range interval), it will not loose information?
