Distributed Kalman filtering over wireless sensor networks in the presence of data packet drops
Bibliographic record
Abstract
We study distributed Kalman filtering over the wireless sensor network, where each sensor node is required to locally estimate the state of a discrete-time linear time-invariant system, using its own observations and those transmitted from its neighbors in the presence of data packet drops. This is an optimal one-step prediction problem under the framework of distributed estimation, assuming the TCP protocol. We first study the stationary distributed Kalman filter (DKF) in the presence of packet drops. The optimal estimation gain is derived based on the stabilizing solution to the modified algebraic Riccati equation (MARE) associated with the DKF. The MARE admits the stabilizing solution, if the stability margin, which can be computed by solving a set of linear matrix inequalities, is greater than or equal to one. Then the Kalman consensus filter (KCF), consisting of the stationary DKF and a consensus term of prior estimates, is proposed, followed by the stability analysis. Finally the performance of stationary DKF and KCF is illustrated by a numerical example.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
