Abstract

fetched live from OpenAlex

In this paper, we study a monotone inclusion problem involving the mixtures of composite and parallel-sum type monotone operators with one of them being a cocoercive operator. Since the resolvent of the composite operator does not have a closed-form solution, the exact three-operator splitting algorithm could not be directly applied. As a result, it is meaningful to propose an effective iterative algorithm to solve this resolvent operator. Based on the primal-dual idea, we first solve the resolvent of the composite operators under suitable conditions. Furthermore, we present two iterative algorithms to solve the composite monotone inclusion problem, and prove their convergence based on the inexact three-operator splitting algorithm. As an application, a corresponding composite convex optimization problem is solved by two novel approaches. Finally, some numerical experiments are investigated on the image deblurring problems to demonstrate the efficiency of the proposed algorithms.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
