While methods for estimating the entropy production rate of a stationary process are relatively well established, this is still a challenge in non-stationary conditions. Here, the authors propose a scheme to infer the exact value of the time-dependent entropy production rate as well as entropy production along with single realizations directly from trajectory data.
