The question is the best lower bound on that dissipation that can be extracted from such partial data.","posed_since":"","precise":"Given a stationary Markov process of which only a coarse-grained observable is recorded (a subset of transitions, or lumped states), determine the largest lower bound on the total entropy production rate $\\sigma$ computable from the observed statistics (waiting-time distributions, current fluctuations, time-irreversibility of observed trajectories), and the conditions under which it equals $\\sigma$. An answer is an estimator with a proof that no other estimator using the same data does better.","problem_ref":null,"references":"","settled_by":"A proof that a given estimator attains the minimum of $\\sigma$ over all Markov processes consistent with the observed statistics.","status_note":"Lower bounds from uncertainty relations, waiting-time statistics and Kullback-Leibler irreversibility are known; optimality among all estimators is not established.","title":"Optimal estimate of total dissipation from partial observation","topic_ref":"7b7d8a136990a4f6c1efa5ee78323494fb4b5c52919f162c25a99c3335a08f49"},"attested":{"attestation":{"batch":null,"client_id":null,"id_token_sha256":null,"kind":"platform"},"record_hash":"20f1ef29280f24501a0a63dd3eecc91137a5f1b533f5efb26f422dc3acb46e3a","schema":"pubphys.attested/1"},"envelope":{"attested_hash":"4c8940bf993326d344ecae78138c184609d4f7fa656cc7ad0d02f3b1890d5e75","platform_signature":{"key_id":"c6afc19b31429869751f06879c75cd64ea92654423d15b44be775bf1310a60da","sig":"2wSfp1KisBp6OLPbE85ZoqRpTmZy4Dh6YjchNe3L8KbUu33Sq6RovvdnD6OCD_JQhUdkMUZfoXAR2KV2CyOVAw"},"schema":"pubphys.envelope/1"},"record_hash":"20f1ef29280f24501a0a63dd3eecc91137a5f1b533f5efb26f422dc3acb46e3a","leaf_index":2116}
