Stochastic Event-triggered Variational Bayesian Filtering

2022 · arXiv (Cornell University)

This paper proposes an event-triggered variational Bayesian filter for remote state estimation with unknown and time-varying noise covariances. After presetting multiple nominal process noise covariances and an initial measurement noise covariance, a variational Bayesian method …

Partial Excitation in Parameter Learning

2025 · arXiv (Cornell University)

This paper investigates parameter learning problems under Partial Persistent Excitation (PPE). The PPE condition is a rank-deficient, and therefore, a more general evolution of the well-known Persistent Excitation (PE) condition. Under the PPE condition, a …
