Abstract

fetched live from OpenAlex

Data sets on Toronto’s safety statistics [1-5], which included the number of accidents, ambulance calls, and crimes were used to produce color-coded maps of Toronto to show “hot spots” in terms of calls to emergency services. The goal of this study was to explore disproportionately high number of requests in some areas - hot spots -compared to the average, and to see if these areas were further away from first responders than areas receiving fewer calls in comparison. We showed that there are neighborhoods in Toronto that can be considered hotspots for emergency requests, and that they are further or similarly distanced from first responders than other neighborhoods with lower accident counts. This project was done for the Big Data Challenge, hosted by the STEM Fellowship, by our group, consisting of three high school students.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
