A neural network approach to selecting indicators for a sustainable ecosystem
Bibliographic record
Abstract
The determination of indicators for monitoring the natural environment to ensure the ecological sustainability of areas under stress is problematic and prone to bias. Further, because of limitations in the resources available for data collection, such indicators should be selected carefully and their number confined to the minimum required to effectively monitor the system under study. Statistical techniques have traditionally been used to help select indicators, but often data lack the requirements of valid statistical analyses: minimal noise, variables linearly separable, variables able to be assigned numerical values, and high dimensionality. In this study, an alternate robust technique, artificial neural networks, is used to examine ecosystem data in multidimensional space and to select the minimum number of measured indicators that have the greatest weight in maintaining a sustainable ecosystem. The case study involves selecting indicators for ensuring the completion of ecologically sustainable army training conducted in a mixed grass prairie ecosystem. A neural network model was created that reduced the number of required measured indicators from 62 to 12, while minimizing researcher bias. Key words: ecological sustainability indicators, neural networks, military training.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
