New zero-one law simplifies one-shot system identification

Researchers have developed a new method for identifying analytic systems from a single experiment, applicable to systems linearly parameterized by prescribed dictionary terms. They proved a sharp zero-one law, indicating that either no input uniquely determines the coefficients or almost every random input from a non-degenerate Gaussian measure does. This approach simplifies one-shot system identification and provides a certificate for recovered models, with numerical examples demonstrating its effectiveness in recovering dynamical systems, nonlinear partial differential equations, and structured matrix families from single trajectory data.

    A zero-one law for one-shot system identification

    arXiv:2607.15832v1 Announce Type: cross Abstract: Can a model be identified from one experiment? We study analytic systems that are linearly parameterized by a combination of prescribed dictionary terms, such as partial differential operators and dynamical systems. For a single i…
