Comparação entre dois métodos para determinação da qualidade da água tratada
Bibliographic record
Abstract
The assessment of water quality destined to population consumption is something essential; for this reason the physical, chemical and bacteriological parameters are monitored and must be according to the limits established in legislation. Thus, the present study has determined and compared the application of two Water Quality Indexes (WQI) of 249 treated water samples, collected in the water supply system of the city of Goiania, during a period of 24 months. These samples were subjected to analysis of 10 physical-chemical parameters and 3 microbiological parameters. The WQI values for the samples were determined using a Canadian WQI calculation model, and also by using different calculation model, employed by the local State Company. The results indicated that the water distributed in 88.8% of the samples were rated as excellent by the two models, indicating that the model employed by local State Company is more restrictive than the Canadian model, besides that there is a seasonal influences pointing to a worse water classification in the rainy season. Keywords: WQI, Water quality, Canadian model.

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.
