Download: http://svn.dsource.org/projects/and/downloads/and-1.1.zip

Added

CostFunction
-Mean Squared Error
-Sum of Squares Error

ActicationFunction
-Tanh

NeuralNetwork
-Added support for momentum ( solution converges much more quickly! ).
-Progress callback ( with setProgressCallback ).
-Added Layer class, for supporting multiple hidden layers.


See test_xor.d for full usage.

Coming Next
Adaptive Learning!
QuickPropogation ( a faster variation on ClassicBackProp )
GA learning

And sometime in the future Self Organizing Maps.

I found same bugs in AND 1.2:
1. subfolder and1.2 in archive file (all files are in root folder too)
2. missing file util.d (module and.util)
3. in file mt.d (module mt) is `import tango.text.locale.Win32;`

4. Linker notify me:
andd.lib(layer)
Error 42: Symbol Undefined _D6object6Object6toUtf8MFZAa
--- errorlevel 1


I linked with DM linker, compiler DMD and std lib phobos, there aren't method toUtf8 in class Object, only toString

And uses tango, found here http://dsource.org/projects/tango/wiki/Download , which is a replacement for phobos, I think it should compile with version=Phobos if you want to use phobos, Ill will check it.
