Abstract

fetched live from OpenAlex

RESUME Les changements climatiques sont devenus l’un des enjeux environnementaux principaux des dernieres annees, les emissions de gaz a effet de serre (GES) etant pointees du doigt comme principal coupable. Globalement, les decideurs des politiques tentent depuis un certain temps de reduire les emissions des GES a travers diverses mesures et politiques. Considerant qu’en Amerique du Nord, le domaine du transport compte pour 30% des emissions totales, il est devenu le centre d’attention pour les initiatives de reduction des emissions de GES.----------ABSTRACT Climate change has become one of the most critical environmental concerns of the past decades, with greenhouse gas (GHG) emissions being identified as the main culprit. Globally, policy makers have been trying to reduce GHG emissions through various policies and strategies; given that in North America, transportation accounts for 30% of the total emissions, it has become the focus of attention for GHG reduction initiatives. The first step to implementing a policy or strategy is to estimate its potential impact on emissions; the use of emission models is necessary to assess the potential impact of those initiatives. Since the 70s, many researchers have developed different models, reaching a peak in the number of studies in the 80s. The emission models have evolved since then and have been regularly updated, but still need improvements. Since these models are extremely sensitive to their input datasets and their methods of calibration, failing to provide accurate input datasets or calibration can result in erroneous stimations.

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.
