Abstract

fetched live from OpenAlex

Estimating the most likely configuration (MAP) is one of the fundamental tasks in probabilis-tic models. While MAP inference is typi-cally intractable for many real-world applica-tions, linear programming relaxations have been proven very effective. Dual block-coordinate descent methods are among the most efficient solvers, however, they are prone to get stuck in sub-optimal points. Although subgradient approaches achieve global convergence, they are typically slower in practice. To improve convergence speed, algorithms which compute the steepest -descent direction by solving a quadratic program have been proposed. In this paper we suggest to decouple the quadratic pro-gram based on the Frank-Wolfe approach. This allows us to obtain an efficient and easy to par-allelize algorithm while retaining the global con-vergence properties. Our method proves superior when compared to existing algorithms on a set of spin-glass models and protein design tasks. 1.

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.
