Recent findings have shown that the brain’s internal representation of the external world shifts over days, a phenomenon termed representational drift [Driscoll et al., 2017, Rule et al., 2020]. Thus, it becomes crucial to account for such non-stationarities when investigating the roles of circuits in the brain. While linear dynamical system (LDS) models are commonly used to characterize the dynamics of neural population activity, they assume a stable mapping from the latent states to neural activity. This limits their ability to capture non-stationary processes---such as representational drif
