Natural Language as an intermediate link for solving not-NLP machine learning problems

Hello.
Recently I've stumbled upon the following RL paper: [https://arxiv.org/abs/2202.08938](https://arxiv.org/abs/2202.08938) , and it made me super curious. In their experiments, an agent acts in the setup of some simple video game, and they use textual descriptions of the environment as an additional information for this agent, to help it to perform a novelty search more efficiently, because textual descriptions express real novelty of a new environment more meaningfully than raw data. As they write: "*we explore natural language as a …
