A deep operator network for Bayesian parameter identification of self-oscillators

Data-Centric Engineering
Many physical systems exhibit limit-cycle oscillations that can typically be modeled as stochastically driven self-oscillators. In this work, we focus on a self-oscillator model where the nonlinearity is on the damping term.
