New POMDP framework separates intent from action in noisy social dilemmas

Researchers have developed a new framework for understanding intentions in social dilemmas where actions are subject to noise. By using a Partially Observable MDP (POMDP) formulation, the model can distinguish between an opponent's intended action and the actual executed action, which may be corrupted by error. This approach, framed within active inference, decomposes the cost function into epistemic and pragmatic components to better infer current intent and its evolution. Experiments in the Iterated Prisoner's Dilemma show that this intention inference provides advantages against conditionally cooperative opponents, but also reveals a critical noise threshold that can lead to cooperation collapse.
