Abstract
We consider a setting engaging in collaborative learning with other machines where each individual machine has its own interests. How to effectively collaborate among machines with diverse requirements to maximize the profits of each participant poses a challenge in federated learning (FL). Our studies are motivated by the observation that in FL the global model attempts to acquire knowledge from each individual machine, while aggregating all local models into one optimal solution may not be desirable for some machines. To effectively leverage the knowledge of others while obtaining the customized solution for individual machine, we propose the accelerated federated training procedures with diversified global models. Based on the federated stochastic variance reduced gradient (FSVRG) framework, we propose the model-based grouping mechanism with adaptive central acceleration (MA-FSVRG) and gradients-based grouping mechanism with adaptive central acceleration (GA-FSVRG) to tackle the challenges of heterogeneous demands. The simulation results demonstrate the advantages of the proposed MA-FSVRG and GA-FSVRG over the state-of-the-art FL baselines. MA-FSVRG exhibits greater stability in performance and significant cost savings in local computation expenses compared to GA-FSVRG. On the other hand, GA-FSVRG attains higher test accuracy and faster convergence speed, particularly in scenarios with limited individual machine participation.

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
