PromptMix: A Class Boundary Augmentation Method for Large Language Model Distillation

1 code implementation22 Oct 2023 Gaurav Sahu, Olga Vechtomova, Dzmitry Bahdanau, Issam H. Laradji

Our specific PromptMix method consists of two steps: 1) generate challenging text augmentations near class boundaries; however, generating borderline examples increases the risk of false positives in the dataset, so we 2) relabel the text augmentations using a prompting-based LLM classifier to enhance the correctness of labels in the generated data.
