Update after author feedback: I thank the authors for their constructive response and hope they can incorporate as many of the promised changes as possible. Based on the feedback and reviewer discussion I now have a better idea of the motivation behind the work. Perhaps a brief description of a concrete example application problem motivating the work would make it easier for others more used to machine learning type learning of dynamical models to appreciate the work too. The experimental evaluation would benefit a lot from explicit comparisons with Bayesian alternatives (e.g. Ruttor et al., NIPS 2013; Svensson et al., AISTATS 2016 and references therein) to properly understand the pros and cons of the different approaches.

Observable operator models (OOMs) and related models are one of the most important and powerful tools for modeling and analyzing stochastic systems. They exactly describe dynamics of finite-rank systems and can be efficiently and consistently estimated through spectral learning under the assumption of identically distributed data. In this paper, we investigate the properties of spectral learning without this assumption due to the requirements of analyzing large-time scale systems, and show that the equilibrium dynamics of a system can be extracted from nonequilibrium observation data by imposing an equilibrium constraint. In addition, we propose a binless extension of spectral learning for continuous data. In comparison with the other continuous-valued spectral algorithms, the binless algorithm can achieve consistent estimation of equilibrium dynamics with only linear complexity.
