Abstract

fetched live from OpenAlex

ProAction® is a mandatory Canadian milk quality assurance program that requires dairy farmers to conduct a biosecurity risk assessment with a veterinarian. Based on this assessment, the veterinarian provides personalized recommendations to improve farm biosecurity, resulting in a large volume of text data. This study aimed to develop a machine learning model capable of automatically classifying these biosecurity recommendations into 12 predefined categories. As the recommendations were written in French or English, all texts were translated into French to ensure consistency in feature extraction and model training. The model was trained on 11,250 manually classified veterinary recommendations from 3825 Québec dairy herds, collected between 2018 and 2021. Three algorithms were tested: Multinomial Naïve Bayes (MNB), Support Vector Machine (SVM), and Random Forest (RF). Performance was evaluated using precision, recall, and F1-score. The SVM achieved the highest performance while maintaining efficient processing time. The trained SVM model was selected to classify new recommendations collected between 2022 and 2024 from herds in Alberta, Ontario and Québec. To evaluate model's performance on this new dataset, a random sample of 250 recommendations was manually classified. The agreement between human classification and model predictions resulted in a Cohen's Kappa of 0.88, suggesting strong agreement. This study highlights the potential of machine learning to classify biosecurity recommendations and support timely, informed decision-making in dairy herd management.

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.
