I Read about those CGC but not the neural gas.
Looks like the new SOM/CGC stuff in FANN is nice, I'll have to look into that as it could make ann_som a very clean implementation.
Any idea if the network saving stuff was fixed? I would need that working for my application.
Thanks for the heads up.

Hey all,
I just wanted to get a sense of the ann_som users out there.
I would like to make some changes/additions, in particular:
Gaussian neighbourhood function to increase convergence with many sensors.
built in function for randomizing sensors (my network has about 4
million weights, which is pretty anoying to use "init" for.)
Maybe more as things move along.
Nice to see someone working on this. I haven't used [ann_som] in earnest, but I have used [ann_mlp], which is great, and am generally interested in the progress of AI things in Pd.
One thing it might be worth looking at is the SOM and Growing Neural Gas support that was added to the FANN library as part of GSoC last year. There is some discussion about it on this thread:
http://leenissen.dk/fann/forum/viewtopic.php?t=46&start=30
The code is also the FANN CVS under the gsoc2007 branch. I did get it to compile at one point but I haven't really tested. It may be in some way informative ?
Anyhow, I look forward to the [ann_som] improvements.
