Synthetic data placement boosts NLP classification performance

By PulseAugur Editorial · [1 sources] ·

Researchers explored the effectiveness of synthetic data augmentation for discourse-pragmatic function classification, a task often hindered by data scarcity. By generating synthetic examples using Llama 3.1 and analyzing their proximity to real data in RoBERTa embedding space, they found that the placement of synthetic data relative to the decision boundary significantly impacts performance. While all augmentation methods improved results over a baseline using only real data, proximal examples yielded the largest gains in macro F1-score, and a balanced mix achieved the highest accuracy. AI

IMPACT This research suggests that strategic placement of synthetic data in representation space can significantly improve NLP model performance, particularly for low-resource tasks.

    The Impact of Synthetic Data Augmentation on Discourse-Pragmatic Function Classification

    arXiv:2609.03652v1 Announce Type: new Abstract: Synthetic data augmentation has become a common strategy for addressing class imbalance in NLP, but most approaches focus on the quantity and diversity of generated examples rather than their geometric relationship to real training …
