Abstract

fetched live from OpenAlex

Lottery gambling is widely enjoyed by Canadians and is the most popular form of legal gambling. As such, discovering and analyzing patterns in lottery gambling data is an important but nontrivial task. In this work, three methods were presented to process and visualize it to the end user to allow for faster pattern discovery. A bubble graph was utilized for the comparative analysis of lottery sales per each neighbourhood of the city of Toronto, Canada. As well, a scatter plot was used to explore the relationship between different neighbourhoods, lottery game product, year, lottery ticket sales, and demographic information. Lastly, a line graph was deployed to compare the jackpot size and ticket sales over time. shinyJackpot is deployed at https://andrewcli.shinyapps.io/shinyJackpot/ for online use. The repository is available at https://github.com/andr3wli/shinyapps.

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.
