Abstract

fetched live from OpenAlex

This dataset contains mobile measurements of ambient methane collected during a controlled release of methane. Methane was released from a stationary source while a vehicle repeatedly drove past the release point, transecting the resulting methane plume multiple times. The objective of the experiment was to evaluate the capability of mobile platforms to detect methane plumes and to examine the relationship between methane release rates (in L/min) and key plume metrics, such as the maximum measured mole fraction and the integrated methane enhancement during individual plume transects. The experiments were conducted in Toronto on October 20 and October 24, 2022.

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.
