Abstract

fetched live from OpenAlex

For decades, satellites have facilitated remote Internet of Things (IoT) services. However, the recent proliferation of increasingly capable and numerous sensors has led to a substantial growth in the volume of data. But legacy Radio frequency-based systems have limited capacity. Hence, free space optical (FSO) communication systems have been proposed, as they allow for high data rates. However, FSO communications are vulnerable to adverse weather. We investigated the potential benefits of using high-altitude platform systems (HAPS) to improve the performance of these networks. In addition, we also developed strategies that use predicted weather conditions to improve the HAPS-enabled networks' performance. Subsequently, we developed a reinforcement learning-based (RL) solution to improve the energy efficiency of satellite-to-ground FSO downlink operations in the presence of adverse weather. We compared the RL solution to a set of simple threshold solutions and found notable performance increases for some network configurations.

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.
