Gradient Knowledge Distillation for Pre-trained Language Models

Lean Wang, Lei Li, Xu Sun

Knowledge distillation (KD) is an effective framework to transfer knowledge from a large-scale teacher to a compact yet well-performing student. Previous KD practices for pre-train…

From Mimicking to Integrating: Knowledge Integration for Pre-Trained Language Models

Lei Li, Yankai Lin, Xuancheng Ren +4

Investigating better ways to reuse the released pre-trained language models (PLMs) can significantly reduce the computational cost and the potential environmental side-effects. Thi…

Dynamic Knowledge Distillation for Pre-trained Language Models

Lei Li, Yankai Lin, Shuhuai Ren +3

Knowledge distillation~(KD) has been proved effective for compressing large-scale pre-trained language models. However, existing methods conduct KD statically, e.g., the student mo…

Text AutoAugment: Learning Compositional Augmentation Policy for Text Classification

Shuhuai Ren, Jinchao Zhang, Lei Li +2

Data augmentation aims to enrich training samples for alleviating the overfitting issue in low-resource or class-imbalanced situations. Traditional methods first devise task-specif…

Alleviating the Knowledge-Language Inconsistency: A Study for Deep Commonsense Knowledge

Yi Zhang, Lei Li, Yunfang Wu +2

Knowledge facts are typically represented by relational triples, while we observe that some commonsense facts are represented by the triples whose forms are inconsistent with the e…

Be Careful about Poisoned Word Embeddings: Exploring the Vulnerability of the Embedding Layers in NLP Models

Wenkai Yang, Lei Li, Zhiyuan Zhang +3

Recent studies have revealed a security threat to natural language processing (NLP) models, called the Backdoor Attack. Victim models can maintain competitive performance on clean…
