CURRENT FEATURES
----------------
- Only layered feedforward networks are supported *directly* at the moment
(for others use the "hooks" provided)
- Unlimited number of layers
- Unlimited number of neurons per each layer separately
- User defined activation function (defaults to logistic)
- User defined error function (defaults to SSE)
- Algorithms implemented so far:
* standard (vanilla) with or without bias, on-line or batch
* momentum with or without bias, on-line or batch
* SuperSAB with or without bias, on-line or batch
* Conjugate gradients
* Jacobian computation
* Computation of result of multiplication between 'vector' and
Hessian
- Some helper functions provided
For full descriptions start with the toplevel "ANN" man page.
