Abstract

fetched live from OpenAlex

This research presents a novel Deep Q-Learning (DQL) framework designed for efficient real-time matching of shipments and vehicles in the freight transportation sector. The framework utilizes the H3 geospatial indexing system for accurate positioning and employs a pre-filtering mechanism to streamline the matching process. When evaluated on a simulated model of Montreal’s transportation network, the framework demonstrates promising results in generating matches that reduce travel distance and prioritize timely service. Through extensive experimentation, a configuration utilizing ReLU activation was identified as particularly efficient, even under limited computational resources. This research contributes to the development of advanced, real-time matching algorithms in logistics and show-cases the potential of integrating reinforcement learning with geospatial analysis to address complex transportation challenges. These findings offer valuable insights for freight companies seeking to improve their matching processes, potentially leading to cost reductions and enhanced service quality.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
