Abstract

fetched live from OpenAlex

A modern radar may be designed to perform multiple functions, such as surveillance, tracking, and fire control. Each function requires the radar to execute a number of transmit-receive tasks. This raises the problem of assigning radar resources, such as the time, frequency and energy budget, to different tasks. Specifically, a radar resource management (RRM) module makes decisions on parameter selection, prioritization, and scheduling of such tasks. RRM becomes especially challenging in overload situations, where some tasks may need to be delayed or even dropped. Such task scheduling is an NP-hard problem. Furthermore, with multichannel, e.g., multi-frequency, radars becoming increasingly viable, multiple tasks can be executed simultaneously. While this greatly enhances the ability to execute tasks, it also complicates task scheduling, now on multiple timelines. In previous work, we had developed the branch-and-bound (B&B) method to solve the NP-hard problem, an approach with exponential computational complexity. In this work, we use the results of the B&B method to train a machine-learning based scheduler. Essentially, we propose to speed up the B&B method by estimating the value of the nodes of the search tree using a neural network. Our results show that the use of neural networks in conjunction with the B&B method results in a close-to-optimal solution while significantly reducing the computational complexity.

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.
