Multiple-Choice Questions are Efficient and Robust LLM Evaluators
This work addresses the need for faster and more robust evaluation methods for LLMs, though it is incremental as it adapts existing datasets rather than creating new tasks.
The authors tackled the problem of inefficient LLM evaluation by introducing multiple-choice versions of existing benchmarks (GSM-MC, MATH-MC, PythonIO), showing that performance correlates strongly with original versions while reducing evaluation time by up to 30 times.
We present GSM-MC, a multiple-choice (MC) dataset constructed by collecting answers and incorrect predictions on GSM8K from 60 open-source models. Through extensive experiments, we show that LLMs' performance on the MC version of this popular benchmark is strongly correlated with their performance on the original version and is quite robust to distractor choices and option orders, while the evaluation time is reduced by a factor of up to 30. Following similar procedures, we introduce MATH-MC, constructed from MATH, and PythonIO, a new program reasoning MC dataset constructed from HumanEval and MBPP. Experimental results indicate that LLMs' performance on these MC benchmarks leaves much room for improvement. Our data and code are available at https://github.com/Geralt-Targaryen/MC-Evaluation.
