Deep neural networks with application in predicting the spread of avian influenza through disease-informed neural networks
Bibliographic record
Abstract
Deep learning has emerged in many fields in recent times where neural networks are used to learn and understand data. This study combined deep learning frameworks with epidemiological models and was aimed specifically at the creation and testing of disease-informed neural networks (DINNs) with a view of modeling the infection dynamics of epidemics. Our research thus trained the DINN on synthetic data derived from a susceptible infected-susceptible infected removed (SI-SIR) model designed for avian influenza and showed the model's accuracy in predicting extinction and persistence conditions. In the method, a twelve hidden layer model was constructed with sixty-four neurons per layer and the rectified linear unit activation function was used. The network was trained to predict the time evolution of five state variables for birds and humans over 50,000 epochs. The overall loss minimized to 0.000006, characterized by a combination of data and physics losses, enabling the DINN to follow the differential equations describing the disease progression.

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.
