ELO Ratings Questions

Key ArgumentThesis: Using ELO for AI agent evaluation = measuring noiseProblem: Wrong evaluators, wrong metrics, wrong assumptions Solution: Quantitative assessment frameworksThe Comparison (00:00-02:00)Chess ELOFIDE arbiters: 120hr trainingBinary outcome: win/lossTest-retest: r=0.95Cohen's κ=0.92AI Agent ELORandom users: Google engineer?
