A lot of work is underway to port old billnet functionality to the newer codebase. KNN, BFGS*, Conjugate Gradient*, Levenberg-Marquardt are already ported. FLF is splited to a library for the most part and the part continues for billnet 0.7

- we have some numerical discrepancies here and there...

ALECO (0 and 2) by S. J. Perantonis and D. Karras are the algorithms that pushed the first order gradient algorithms to the limit.

The back propagation family is the base of all gradient learning machines. The current billnet's implementation can be used with:
-the cross entropy cost function
-the online and offline type of learning
-the sigmoid output function
-the tanh output function (untested)

We are slowly getting our scripts up to speed with savannah infrastructure. Hopefully more algorithms will follow soon.
