Rabbit lecturer

How it works

Uses a statistical model to learn your preferences from pairwise comparisons. Prioritizes asking about items you're uncertain about, so you don't waste time on obvious choices.

If you're rescoring an existing list, your current scores are used as a starting point.

Technical details

Fits a Plackett-Luce preference model using the MM algorithm. For rescoring, original scores seed the model as a soft prior (MAP regularization). Pair selection uses active-learning policies. Uncertainty via bootstrap resampling. Tier list uses 1D k-means. Inspired by Gwern's Resorter.
