Goal-directed manipulation of representations is a key element of human flexible behaviour, while consciousness is often related to several aspects of higher-order cognition and human flexibility. Currently these two phenomena are only partially integrated (e.g., see Neurorepresentationalism) and this (a) limits our un…

Sparse reward problems are one of the biggest challenges in Reinforcement Learning.

Many AI problems, in robotics and other domains, are goal-directed, essentially seeking a trajectory leading to some goal state.
