Autoencoder-Based Parameter Estimation for Superposed Multi-Component Damped Sinusoidal Signals
Momoka Iida, Hayato Motohashi, Hirotaka Takahashi
Damped sinusoidal oscillations are widely observed in many physical systems, and their analysis provides access to underlying physical properties. However, parameter estimation bec…
