Curriculum Debiasing: Toward Robust Parameter-Efficient Fine-Tuning Against Dataset Biases

ACL 2025long

Parameter-efficient fine-tuning (PEFT) addresses the memory footprint issue of full fine-tuning by modifying only a subset of model parameters. However, on datasets exhibiting spurious correlations, we observed that PEFT slows down the model’s convergence on unbiased examples, while the convergence…

Client-Customized Adaptation for Parameter-Efficient Federated Learning

ACL 2023findings

Despite the versatility of pre-trained language models (PLMs) across domains, their large memory footprints pose significant challenges in federated learning (FL), where the training model has to be distributed between a server and clients. One potential solution to bypass such constraints might be…

Improving Bias Mitigation through Bias Experts in Natural Language Understanding

EMNLP 2023long main

Biases in the dataset often enable the model to achieve high performance on in-distribution data, while poorly performing on out-of-distribution data. To mitigate the detrimental effect of the bias on the networks, previous works have proposed debiasing methods that down-weight the biased examples i…

SMoP: Towards Efficient and Effective Prompt Tuning with Sparse Mixture-of-Prompts

EMNLP 2023short main

Prompt tuning has emerged as a successful parameter-efficient alternative to the full fine-tuning of language models. However, prior works on prompt tuning often utilize long soft prompts of up to 100 tokens to improve performance, overlooking the inefficiency associated with extended inputs. In thi…

Tutoring Helps Students Learn Better: Improving Knowledge Distillation for BERT with Tutor Network

EMNLP 2022main

Pre-trained language models have achieved remarkable successes in natural language processing tasks, coming at the cost of increasing model size. To address this issue, knowledge distillation (KD) has been widely applied to compress language models. However, typical KD approaches for language models…
