Random Forest explained: how a forest of trees votes, measured on 42 years of Chilean weather
In 64 seconds and narrated: the viral Random Forest diagram draws the trees in a chain, and that is boosting. On eight cores, 200 trees drop from 26.1 to 3.5 seconds; AUC climbs from 0.69 with one tree to 0.88 with a hundred; a column of pure noise looks important with the default measure; and trained on cold months from 1984 to 2012, the forest never predicted above 28.9 °C in the summers of 2016 to 2026. Muted by default: turn the sound on in the controls.
