It is common to address the curse of dimensionality in Markov decision processes (MDPs) by exploiting low-rank representations.

While deep RL should automatically acquire such good representations, prior work often finds that learning representations in an end-to-end fashion is unstable and instead equip RL algorithms with additional representation learning parts (e. g., auxiliary losses, data augmentation).
