Making Pre-trained Language Models Better Continual Few-Shot Relation Extractors

1 code implementation24 Feb 2024 Shengkun Ma, Jiale Han, Yi Liang, Bo Cheng

Continual Few-shot Relation Extraction (CFRE) is a practical problem that requires the model to continuously learn novel relations while avoiding forgetting old ones with few labeled training data.

Generative Prompt Tuning for Relation Classification

1 code implementation22 Oct 2022 Jiale Han, Shuai Zhao, Bo Cheng, Shengkun Ma, Wei Lu

Current prompt tuning methods mostly convert the downstream tasks to masked language modeling problems by adding cloze-style phrases and mapping all labels to verbalizations with fixed length, which has proven effective for tasks with simple label spaces.
