A dataset containing 1001 species occurrences available in GBIF matching the query: { "and" : [ "DatasetKey is one of (Occurrence and percent cover of the colonial invasive tunicate Didemnum vexillum from near-seafloor drift transect video imagery and high-resolution digital still images in the western Bay of Fundy, Canada, Nonindigenous Aquatic Species (NAS) Database Non-freshwater Specimens, Norwegian Species Observation Service, SWG Coastal and marine invertebrate observations, Verified marine records from Indicia-based surveys, Observation.org, Nature data from around the World, National Invasive Species Database, Programme BioObs: observations naturalistes en milieux aquatiques-Observations de BioObs., 2004-2012 Bishop et al.

Data from some individual datasets included in this download may be licensed under less restrictive terms.

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.

Teacher imitation

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.
