Synonym Replacement, Random Insertion / Random Swap / Random Deletion 방식을 사용하여 Data Augmentation 을 한다. 기존 방법들과 달리 외부 데이터나 모델 훈련 없이 성능을 증가 시킬 수 있었다.
개인적 견해
We present EDA: easy data augmentation techniques for boosting performance on text classification tasks. EDA consists of four simple but powerful operations: synonym replacement, random insertion, random swap, and random deletion. On five text classification tasks, we show that EDA improves performance for both convolutional and recurrent neural networks. EDA demonstrates particularly strong results for smaller datasets; on average, across five datasets, training with EDA while using only 50% of the available training set achieved the same accuracy as normal training with all available data. We also performed extensive ablation studies and suggest parameters for practical use.
