Abstract

fetched live from OpenAlex

This paper shows how SilviScan-3 data can be used to map the within-tree distributions of wood properties, and to compute relevant statistics useful for tree-to-tree comparisons. An algorithm named EvaluTreeMap was developed for this purpose, based on subdividing the stem into triangular elements. It was validated using a stem of conical shape with properties exhibiting conical symmetry. To illustrate some applications of the program, it was used for the preliminary evaluation of the impact of Armillaria root disease on the fibre coarseness of Douglas-fir trees. Key words: SilviScan-3, fibre properties, within-tree variations, EvaluTreeMap, meshing, mapping, stem volume, tree's mean properties and standard deviation, Armillaria ostoyae, fibre coarseness, Douglas-fir

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.
