3.3 Ablation Study

  1. Which ablations showed that chain of thought isn’t just an equation, extra computation, or knowledge activation?
    Equation-only prompting barely helped on GSM8K (questions too hard to translate directly into equations), though it helped on 1–2-step data sets. Outputting a matching number of dots (variable compute only) did about as well as the baseline. Putting the chain of thought after the answer also did about as well as the baseline.
