Abstract
Cameras are widely used in many fields, e.g., intelligent transportation, autonomous driving, surveillance, etc. It is thus vital to conduct video analytics in an efficient and accurate manner. However, camera’s built-in capacity is insufficient to support neural network processing, while offloading video streams incurs prohibitive latency and communication cost. In this paper, we find that frame rate, resolution, and neural network inference model, have an intertwined impact on network resource demand. The optimal configuration of these factors also varies with video content feature. To address these challenges, we propose a dynamic configuration update scheme based on predictive video perception using a long short-term memory (LSTM) neural network, to adapt configuration to content changes. This scheme consists of a change detector and a configuration profiler. Through theoretical modeling and analysis, we derive the detection thresholds for both dynamic and stationary video contents, considering the LSTM prediction error. The configuration profiler then updates system by solving an optimization problem, which maximizes the overall utility considering analytics accuracy and resource consumption. Extensive real-world traces-based experiments show that the proposed scheme can save profiling resources by up to 95% while ensuring high accuracy compared with other benchmarks.

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
