Neural network embeddings have 3 primary purposes: Finding nearest neighbors in the embedding space. Second, robot skills are generated Importantly, our method learns to control a real robot in joint-space to achieve these high-level tasks with little or no on-robot time, despite the fact that the low-level policies may not be perfectly transferable from simulation to real, and that the low-level skills were not trained on any examples of high-level tasks.
