Context and Location Awareness in Eco-Driving Recommendations
Bibliographic record
Abstract
Eco-driving techniques are methods that drivers can take in order to improve their vehicles’ fuel efficiency. One way of implementing such methods is to recommend changes in driving habits focusing on saving fuel. Recommendation systems in the context of efficient driving may take numerous data sources as input and serve multiple purposes. In this work, we develop a recommendation system that suggests changes in engine revolutions per minute (RPM) that reduce fuel consumption. We simulate the effects of this system using a vehicular sensor dataset that contains location, speed, RPM, and consumption. We also investigate the effects of including location data in the recommendations as a way to leverage local habits and behaviors. Both methods reduced fuel consumption in all recorded trips. Moreover, using only local data yielded a mean fuel reduction of 43%, whereas using the entire dataset reduced the fuel consumption in 56% on average. Upon analyzing the resulting changes, we noted that such a difference in fuel consumption is due to the local recommendations not having access to global optimal data points and accounting for local behavior that is affected by aspects such as terrain.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
