Abstract
Connected vehicles play a crucial role in enhancing safety and comfort within Intelligent Transportation Systems. The 5G technology offers high bandwidth, ultra-low latency, and high reliability with small cell densification, which is essential for efficient data sharing among connected vehicles. However, the limited range of 5G cells presents challenges, including frequent handovers (HO), which can lead to unnecessary HOs, HO failures, ping-pong effects, and packet loss, ultimately degrading user experience. To address these challenges, a proactive handover decision strategy based on a comprehensive analysis of network conditions is necessary to ensure stable connections. We introduce a holistic connectivity-oriented hybrid spatio-temporal graph-oriented approach, HCO-PHD, which leverages Graph Convolutional Networks and Long Short-Term Memory to capture spatial dependencies and temporal patterns across the network, proactively enabling HO decision-making. HCO-PHD enhances connection stability by dynamically assessing real-time network changes and making informed HO decisions in highly mobile and ultra-dense environments. Simulation results demonstrate that HCO-PHD significantly improves the efficiency of HO decision-making, ensuring stable connectivity and minimizing disruptions caused by HOs, outperforming existing approaches.

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
