Abstract

fetched live from OpenAlex

Satellite Edge Computing (SEC), which empowers satellites with computing capabilities, has been regarded as a promising paradigm for 6G alongside the development of mega-Low Earth Orbit (LEO) satellite constellations. With SEC, tasks traditionally performed on the ground can be offloaded and processed in the sky. Currently, most existing studies assume that the service entities have been deployed on satellites in advance, ignoring the selection of specific serving nodes. However, as the communication and computing resources of satellites vary in accordance with time, selecting the optimal node for deploying the service entity and migrating it at the right time will significantly affect users' quality of experience. In this regard, this article investigates the online service deployment on mega-LEO satellite constellations, taking into account the time-varying on-board resources and limited visible time. We formulate an optimization problem to maximize the number of successful deployments that meet delay requirements for each user under the long-term migration cost constraint. To solve this problem, we transform it into a Markov decision process and propose COMPOSE, an online satellite service deployment scheme based on convolution-proximal policy optimization. COMPOSE dynamically selects the optimal serving node and migrates the service entity in due course. The simulation results demonstrate the superior performance of COMPOSE in terms of delay satisfaction ratio, delay variance, and the number of migrations.

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.
