A new paper explores the potential of pretrained tabular foundation models (TabFM) to act as training-free world models for reinforcement learning and robot planning. The research found that TabFM outperformed models like LSTM and MLP trained from scratch on limited data, particularly in robot locomotion tasks. However, its accuracy significantly depends on the amount of context provided, with long contexts yielding better results but still falling short of fully trained world models. The study concludes that while training-free priors are useful in data-scarce scenarios with sufficient context, they are not yet a replacement for trained world models in planning applications. AI
