New algorithm PEC distinguishes non-Markovian decision processes

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new algorithm called PEC to determine if data collected under a fixed policy can distinguish between two candidate Non-Markovian Decision Processes (RDPs). They proved that observationally equivalent candidates maintain equal prior and posterior odds, even when the policy visits every automaton state. The PEC algorithm can decide this equivalence in time linear to the product automaton's size, and it successfully restored distinguishability in three out of four test environments where prior work's assumptions failed.

    Exact Distinguishability in Non-Markovian Decision Processes

    arXiv:2610.01527v1 Announce Type: cross Abstract: Non-Markovian environments are often modeled as Regular Decision Processes (RDPs), where dynamics depend on the interaction history through a finite automaton. Existing offline guarantees for RDPs rely on a distinguishability assu…
