Dara Shayda replied to Dara Shayda's discussion Book: Neural Network Control of Nonlinear Discrete-Time Systems in ArduCopter Evolution Team
"I read the code for several NN packages out there on the net. 

The problem is the generality of the code:

1. To make NN work for an actual system e.g. ArduCopter there are tons of constants and training parameters need to be identified. 

2. Error…"

"Errata: 

/* NN control should only be called when deviating off the desired path */ if (delta < threshold)

typo it should be:

if (delta > threshold)"
