5 Symbolic Reasoning

  1. Which symbolic reasoning tasks did Wei et al. use, and what did they show?
    Last-letter concatenation (“Amy Brown” → “yn”) and coin-flip state tracking. With CoT, PaLM 540B solved in-domain cases almost perfectly, and CoT enabled length generalization to more words or flips than in the exemplars, where standard prompting failed; small models failed even in-domain.
