New method embeds information in AI policy randomness

Researchers have introduced a novel method called posterior-matching randomness modulation (PRAM) to embed information within the random actions of a stochastic policy in Markov Decision Processes (MDPs). This technique allows information to be communicated implicitly by modulating action realizations without changing the overall action distribution. PRAM is framed as a channel coding problem and is proven to be asymptotically reliable, enabling message decoding with minimal error as state trajectories lengthen. The paper demonstrates PRAM's utility in applications such as multi-bit policy watermarking and trajectory provenance. AI
