Abstract
A fundamental issue in Bayesian decentralized estimation over a sensor network is the inadvertent multiple re-use of data also known as data incest. We show the relationship between data incest and the network topology by using a graph theoretical formulation. A novel necessary and sufficient condition based on the topology of the network is derived so that data incest management can be optimally achieved. This approach requires large storage capabilities at the sensor level. In the case of an arbitrary network, if the necessary and sufficient condition for data incest does not hold then finding a sub-optimal strategy requires solving a 0-1 integer optimization problem where the dimension of the vector to optimize increases with time. Numerical results illustrate the effectiveness of our approach.

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 it
