Abstract

fetched live from OpenAlex

We propose efficient scheduling algorithms for down-link MIMO-CDMA systems using zero forcing beamforming to achieve high system throughput with low computational complexity. Based on a graph theoretical approach, we propose to represent the system as a graph and to formulate the scheduling problem as the maximum weight k-colorable subgraph problem. The proposed algorithms make use of two heuristic solutions to find the scheduled users in each time slot in an acceptable polynomial time. We evaluate the efficiency of the proposed schedulers and the results demonstrates that it can achieve near-optimal performance with very low complexity compared to the optimal exhaustive search.

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.
