Abstract

fetched live from OpenAlex

A search for primary evidence of Earth's ancient atmosphere and climate Robert Rainbird, a research scientist working for the Geological Survey of Canada, a division of Natural Resources Canada, looks at the geological evolution of Earth’s ancient atmosphere and climate. What did Earth look like two and a half billion years ago? When did our atmosphere and oceans become oxygen-rich? Did oxygenation occur rapidly or via incremental oscillations over millions of years? These questions have been debated by scientists for decades because of their implications for the evolution of early life on Earth. Through their research, Dr Robert H. Rainbird and his team at the Geological Survey of Canada and Carleton University (Ottawa) seek to answer these questions by investigating rocks from an ancient sedimentary basin north of Lake Huron in Ontario.

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.
