Abstract

fetched live from OpenAlex

An approach was developed for combining streamflow drought information from synthetic (generated) data with data reconstructed based on palaeoclimatic information (tree ring widths).The tree ring data were used to reconstruct streamflow in periods when no streamflow data were collected.The reconstructed data were then used as a source of historical data for estimating drought severity quantiles.The generated data were obtained using a nearest neighbour resampling method while the tree ring reconstruction was accomplished using a regression model.The application of the approach was to data from the Athabasca River in Alberta, Canada.The results demonstrate the feasibility and the utility of the approach for obtaining more accurate and precise estimates of extreme drought severity quantiles. Key words historical data; nearest

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.
