Abstract

fetched live from OpenAlex

Both Android and Apple compatible. Free for the mobile app, although the Polar H6 and H7 sensors cost US$89. Additionally, there are four upgrades users can purchase for between $2.99 and $3.99. Polar Beat is an exercise-tracking application that provides users with detailed tracking of the duration, distance and intensity of their training sessions. Competing in the same market as Strava and Nike+, Polar Beat provides users with another app-based means of tracking and analysing their workouts. Utilising the built in global positioning system and accelerometry of the mobile devices, the app tracks the users’ speed, distance and route travelled. Although users are not obligated to purchase and wear a heart rate (HR) sensor, the app is designed to track real-time heart rate using the Polar H6 or H7 sensors. The integration of HR will come as no …

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.
