Neurons, glass, & silicon


Clearly the swashplate neural network has nicely decoupled the 3 swashplate axes since the long coveted single module for navigation made no difference. We're looking for significant improvements here, but all the designs seem to have milked the last bit of information out of 1 Hz GPS.

There's a slight chance adding MEMS acceleration to the 3 module network improved its altitude hold. More evolutions to grind than the 1 module network.

Would be nice if the software could automatically throttle the evolutions to hit an exact CPU load. It's the times it gets it wrong that we're worried about.

1 module, 30 sec history
----------------------------
current GPS acceleration
commanded tilt

\/
predicted GPS acceleration

same as 3 modules




3 module, 30 sec history
----------------------------
current GPS acceleration
current MEMS acceleration
commanded tilt
|
\/
predicted GPS acceleration

Same as without MEMS.
Significant oscillation during training.
Possibly better altitude hold.





3 module, 60 sec history
----------------------------
current GPS acceleration
commanded tilt

\/
predicted GPS acceleration

Same as 30 sec.
Longer training time.

So much for that.

Given that anything with a built-in air conditioner is $2 million here, ghetto is king.
