There are similarities. The difference in two approaches are: - FEP is Bayesian in nature, while there's usually no notion of uncertainties in curiosity driven RL - In FEP, there's no explicit weighting of explore/exploit tradeoff. It automatically emerges from equations - FEP, since it's Bayesian, allows for more complex reasoning (like counterfactuals) - Curiosity driven RL is scalable while FEP is not feasible for anything other than simple models
