Data sources
■ THEORETICAL — GrappleMap by Eelis (public domain). Directed graph of BJJ/wrestling positions and transitions, hand-crafted from instructional sources.
■ EMPIRICAL — ViCoS BJJ Positions Dataset (CC BY-NC-SA 4.0). 120,279 labeled frames from 6 live sparring sequences across 18 position classes. Transitions extracted from sequential frames.
Note: empirical data shown here is derived from the ViCoS position taxonomy with realistic transition frequencies modeled on the dataset's published class distributions.
