New method enables AI agents to learn complex hidden-state systems

Researchers have developed a new method for autonomous agents to learn and reason about systems with hidden states, a problem often framed as learning a discrete Partially Observable Markov Decision Process (POMDP). The agent starts with knowledge of the POMDP's actions and observation spaces but must construct its state space, transitions, and observation models from sequential data. The proposed approach, building on Spectral methods like Predictive State Representations (PSRs), learns POMDP matrices up to a similarity transform estimated via tensor decomposition. This method allows for the generation of new plans for different goals and reward functions after the model has been learned, and it also demonstrates the impossibility of learning a POMDP beyond a partition of states from sequential data alone.

    Toward Learning POMDPs Beyond Full-Rank Actions and State Observability

    arXiv:2601.18930v4 Announce Type: replace-cross Abstract: We are interested in enabling autonomous agents to learn and reason about systems with hidden states, such as locking mechanisms. We cast this problem as learning the parameters of a discrete Partially Observable Markov De…
