THE LAB · UNBLACKBOXING WITH THE KIT
Eighteen experiments run with Lars's Williams Structured Random Forest the way it is meant to be used: not as a black box that scores, but as a reader that finds the zone boundaries in the data and prints them, so the rules it found can be set beside the laws that made the data. Every number below comes from a script in sitoolz/experiments/ that anyone can rerun in under two minutes.
WSRF (the Williams Theorem, 2011, William Lars Rocha) first discovers global zone boundaries in the data, then fits a forest per zone; the boundaries are readable. The kit carries the library as sitoolz.wsrf, the exported-forest reader as sitoolz.forests, and the zones engine (the Z/13 ring, GF(k) parity, the Connect-4 evaluator) as sitoolz.zones. The Zone Table and the poker room on this site are the same forest at work on cards.
