Inverse Models Predict Mirroring Offsets and Explain the Acquisition
... Control-theoretic inverse models are very useful for learning and generating flexible sensorygoal directed motor behaviors. We have recently proposed a simple eligibility-weighted Hebbian learning rule capable of provably forming inverse models in high dimensional linear networks by associating rand ...
