Visual Analytics for Public Health: Supporting Knowledge Construction and Decision-Making
Bibliographic record
Abstract
Massive and complex data impose a challenge on the public health community to explore, analyze, and synthesize valuable information to make timely informed decisions. This study exploits the use of Visual Analytics (VA) to enable health professionals to understand heterogeneous injury data and decide about dynamic health situations. Visual Analytics is defined as the “science of analytical reasoning facilitated by interactive visual interface”[14]. We conducted collaborative Paired and Group Analytics sessions to examine how VA assists health professionals in investigating injury data as well as in supporting knowledge construction and decisionmaking. This manuscript reports how stakeholders perceived VA to be usefulness in helping them understand the injury data, get insights and build knowledge that could potentially prompt actions into critical health situations. Future study implications can inform the design of innovative VA tools and techniques that synthesize novel collaborative VA approaches to optimize the decision-making process.

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.
