Impact of Pretraining Term Frequencies on Few-Shot Reasoning

Razeghi, Yasaman, Logan IV, Robert L., Gardner, Matt et al.

Understand

Pretrained Language Models (LMs) have demonstrated ability to perform numerical reasoning by extrapolating from a few examples in few-shot settings.

  • However, the extent to which this extrapolation relies on robust reasoning is unclear.
  • In this paper, we investigate how well these models reason with terms that are less frequent in the pretraining data.
  • In particular, we examine the correlations between the model performance on test instances and the frequency of terms from those instances in the pretraining data.
