Reinforcement Learning is an essential ability for robots to learn new motor skills. Nevertheless, few methods scale into the domain of anthropomorphic robotics. In order to improve in terms of efficiency, the problem is reduced onto reward-weighted imitation. By doing so, we are able to generate a framework for policy learning which both unifies previous reinforcement learning approaches and a...

One of the most general frameworks for phrasing control problems for complex, redundant robots is operational-space control. However, while this framework is of essential importance for robotics and well understood from an analytical point of view, it can be prohibitively hard to achieve accurate control in the face of modeling errors, which are inevitable in complex robots (e.g. humanoid robot...

Improvement of Corneal Opacity in Peters' Anomaly

A 5-week-old male presented with Peters' anomaly. Corneal transplantation was deferred and the patient underwent an optical sector iridectomy in his better eye with central leukoma and iridocorneal adhesions. At six months following surgery, there was a decrease in corneal opacity. The most recent ophthalmic examination was performed at age 42 months. The cornea was considerably clearer, and th...
