Abstract

fetched live from OpenAlex

This paper studies the problem of reaching consensus resiliently in the presence of misbehaving nodes. We design a consensus algorithm where, at each time-step, each node updates its value as a weighted average of its own value and the median of its neighbors' values. This algorithm requires no global information about the network, and is computationally lightweight. We develop a novel graph property that we term excess robustness, and use this property to characterize the ability of the median algorithm to succeed under various fault models. We also provide a construction for excess robust graphs. We show that the sensitivity of this algorithm varies greatly under different fault models, and make connections to related ideas from the literature on contagion and graphical games.

Full frame distilled prediction

Teacher imitation

Not 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.
