Abstract

fetched live from OpenAlex

The National Hockey League (NHL) is using a puck and player tracking (PPT) system that records the location of the puck and players during games. Data is recorded 12 times per second for each player on the ice and 60 times per second for the puck. There are tremendous opportunities for the use of this data, including the development of new metrics that can be used for a variety of purposes. However, there are also significant challenges that need to be overcome. In this talk I first describe several such challenges and opportunities. I then focus on one of the opportunities we have been exploring, which is to develop several passing metrics. I briefly describe some of these metrics, the intuition behind them and outline some possible uses for a few metrics. This is talk is based on joint work with David Radke, Daniel Radke and Alex Pawelczyk.

Full frame distilled prediction

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.
