Synonym-Based Text Augmentation Reduces Calibration Error in Zero-Shot Multimodal Models

Abstract

Abstract: This report synthesises findings from 15 peer-reviewed papers addressing the following research question: What is the impact of synonym-based text augmentation on the calibration error of zero-shot multimodal models under out-of-distribution shifts. Since the establishment of vision-language foundation models as the new mainstay in low-shot vision classification tasks, the question of domain generalization arising from insufficient target data is assuming more importance. This scarcity challenge induces sampling bias and. 11 claims were extracted from source literature; 2 were independently verified against retrieved documents. An automated multi-reviewer quality assessment produced a score of 4.9/10. This report is a machine-generated literature synthesis and does not constitute original research.
