What did the authors do?
The authors investigated how transformers can learn RL strategies directly from in-context experience without explicit reward signals or traditional planning methods. Their approach included:

  • Training a GPT2-style transformer with 3 layers and 512-dimensional embeddings on two types of navigation tasks: gridworlds and tree mazes, modeled as Markov Decision Processes (MDPs).

  • Providing the model with an in-context dataset of interaction tuples (state, action, next state, reward) generated via a heuristic-based random walk policy to mimic animal exploration.

  • Using a custom attention mask to prevent the query state from attending to itself or to context tokens involving the query, encouraging the model to learn how to use context effectively.

  • Evaluating the model’s ability to predict the optimal action for a new query state in held-out environments with novel sensory inputs and reward locations.

  • Applying interpretability techniques such as linear decoders, integrated gradients, attention ablations, and cross-environment correlation analyses to understand the learned representations and mechanisms.

  • It discovered shortcut paths and learned in-context structure representations that aligned with the environment’s geometry and hierarchical organization.

  • Representations encoded spatial relationships such as goal-relative angles and Euclidean geometry in gridworlds, as well as hierarchical structure in tree mazes.

  • The RL strategy relied on caching intermediate computations in memory tokens accessed at decision time, rather than on standard value gradients or explicit path planning.

  • Cross-environment alignment of representations increased with longer context lengths, supporting generalization to novel environments.

  • Limitations include the focus on relatively simple 2D navigation tasks and the need to explore how these mechanisms scale to more complex, high-dimensional environments.
