While not the first to develop a virtual world to provide suitable simulations to accelerate reinforcement learning, this world certainly seems to be one of the most complex. It'll be interesting to see how effective these simulations actually are in the real world; so far though, there are no robots complex enough to actually fully enact what they've "learnt".

The goal of VirtualHome is to help robots learn tasks by first experiencing them in a virtual system. In the current system, an avatar can perform 1,000 separate actions, broken down as subtasks, in…
