Learning? Maybe, a rather naive and simple approach!

(Günther & Ruder, 2003) (Bayer, 2017) (Walter & Schmitt, 2012) (Le Mouel, Martin et al., in prep) (Suissa, 2018) (Häufle et al., 2019) (Driess et al., 2018)

Given a specific control idea, learning is ...

Ï finding appropriate muscle stimulation pattern, time to change pattern, etc.,using trial and error (heuristics) or fmincon (gradient-based methods)

Ï optimising controller gains using Bayesian optimisation,

Ï balancing feedforward and feedback contributions using heuristics,

Ï autonomously learn the control policy using an artificial neural network andsequential quadratic programming.
