Abstract

fetched live from OpenAlex

Dynamic planning involves continuously updating a map by sensing changes in the environment and planning appropriate actions, with all tasks sharing common computational resources. We use harmonic functions for dynamic planning. Analogous representations of harmonic functions as Markov chains and resistor networks are used to develop the notion of escape probability and energy dissipation. These measures are used to indicate convergence (event that permits resources to be devote to non-planning tasks) more robustly than monitoring maximum or average field changes between iterations. The convergence of the harmonic function is related quadratically to the number of grid elements. An example of an irregular sampling strategy - quad tree - is developed for harmonic functions, which is complete yet imprecise. Quad trees are not a sufficient sampling strategy for addressing the exponential growth of multiple dimensions and therefore current investigations include other sampling strategies or dimensional parallelization.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
