Researchers have developed new methods for identifying linear dynamical systems, particularly when prior structural information about the system matrix is available. One paper focuses on convex constraints, deriving error bounds that improve estimation accuracy for smaller sample sizes compared to unconstrained methods. The second paper addresses the joint learning of multiple linear dynamical systems, proposing a total variation penalized estimator that can achieve accurate estimation even with constant trajectory lengths as the number of systems increases, especially when systems vary smoothly or have few jumps across a connected graph.
