Abstract

fetched live from OpenAlex

We study the problem of handling timeliness and criticality trade-off when gathering data from multiple resources in complex environments. In IoT environments, where several sensors transmitting data packets - with various criticality and timeliness, the rate of data collection could be limited due to associated costs (e.g., bandwidth limitations and energy considerations). Besides, environment complexity regarding data generation could impose additional challenges to balance criticality and timeliness when gathering data. For instance, when data packets (either regarding criticality or timeliness) of two or more sensors are correlated, or there exists temporal dependency among sensors, incorporating such patterns can expose challenges to trivial policies for data gathering. Motivated by the success of the Asynchronous Advantage Actor-Critic (A3C) approach, we first mapped vanilla A3C into our problem to compare its performance in terms of criticality-weighted deadline miss ratio to the considered baselines in multiple scenarios. We observed degradation of the A3C performance in complex scenarios. Therefore, we modified the A3C network by embedding long short term memory (LSTM) to improve performance in cases that vanilla A3C could not capture repeating patterns in data streams. Simulation results show that the modified A3C reduces the criticality-weighted deadline miss ratio from 0.3 to 0.19.

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.
