Abstract

fetched live from OpenAlex

This dataset contains maps of the snow cover area over the Kananaskis Country (Canada) from 01 September 2017 to 31 August 2018. The products were derived from Sentinel-2 observations. All available Sentinel-2 level 1C products were processed to level 2A (surface reflectance and cloud mask) using the MAJA software. Then, level 2A products were processed using the LIS software to generate the snow cover maps. The area is covered by four tiles: T11UPT (81 dates), T11UPS (116 dates), T11UNT (114 dates), T11UNS (87 dates). The data are provided as GeoTIFF images coded as follows: 0: No-snow 100: Snow 205: Cloud including cloud shadow 255: No data Read more about these products in this blog post.

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.
