Abstract

fetched live from OpenAlex

Travel surveys as well as freight transport surveys are the basis for any fact-based transport policy. It needs to be stressed that the collection of data and description of the existing mobility behaviour and transport demand is linked to a considerable amount of uncertainty. Therefore, it is greatly important to assure the quality of the collection of travel behaviour data. If one considers the current guidelines for planning and surveys, from that point of view, it is amazing how little attention is paid to the disclosure of the data quality and uncertainty directly. Therefore, the standardized definition of requirements to achieve high quality for survey results is essential. This workshop tried to further develop validation procedures in order to come closer to the "ground truth" in surveys.

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.

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.
