EleutherAI's blog post introduces and analyzes four distinct methods for evaluating language model performance on multiple-choice tasks. These methods, including unnormalized, token-length normalized, byte-length normalized, and unconditional likelihood normalized scores, address the challenge of comparing continuations of varying lengths. The post highlights the trade-offs of each approach, particularly concerning tokenization dependence and computational requirements, with byte-length normalization emerging as a tokenization-agnostic solution.
