You may use neural networks in R (using the GRASS-R interface).
For a general overview of the integration, see

As my master thesis, I wrote these two modules:

i.spec.sam: Spectral Angle mapping
http://grass.osgeo.org/wiki/Addons#i.spec.sam

i.spec.unmix: Spectral unmixing
http://grass.osgeo.org/wiki/Addons#i.spec.unmix

The latter needs proper update to GRASS 6 but that should not be too hard.
