Predicting Closed-Loop Performance of Latent World Models: Offline Checkpoint Selection for MPC and Model-Based RL Under Non-Markovian Rewards in LunarLander

arXiv 2026 35.4 method

TLDR

Proposes offline checkpoint selection metrics for latent world models, using Reward Observability Fraction to predict closed-loop performance in LunarLander.

Reasoning

Strengths include novel diagnostic metrics (ROF, CROF) for checkpoint selection and empirical validation showing improved performance. Weaknesses are limited scope (LunarLander with shaped rewards) and potential lack of generalizability.
