A GRU-Augmented Kalman Filter for State Estimation in Systems with Colored Noise

Although the Kalman filter is optimal for linear Gaussian systems, its performance degrades in practical scenarios when noise is colored rather than white. Additionally, the Kalman filter requires substantial domain knowledge to derive parametric forms. To overcome these limitations, this paper proposes a data-driven f...
