DAFNet: Dynamic Auxiliary Fusion for Sequential Model Editing in Large Language Models (2024.findings-acl)

Copied to clipboard

Challenge: Large language models (LLMs) have shown impressive results, but still suffer from hallucination, i.e., the generation of false information.
Approach: They propose a task of sequential model editing that aims to rectify mistakes continuously.

HiCLRE: A Hierarchical Contrastive Learning Framework for Distantly Supervised Relation Extraction (2022.findings-acl)

Copied to clipboard

Challenge: Existing approaches of distantly supervised relation extraction (DSRE) focus on sentence-level or bag-level de-noising, neglecting the explicit interaction with cross levels.
Approach: They propose a hierarchical contrastive learning framework for distantly supervised relation extraction to reduce noisy sentences.
Outcome: The proposed framework outperforms baselines in various mainstream DSRE datasets.
AdaTooler-V: Adaptive Tool-Use for Images and Videos (2026.findings-acl)

Copied to clipboard

Challenge: Existing models exhibit blind tool-use reasoning patterns, which significantly increases inference overhead and degrades model performance.
Approach: They propose an MLLM that performs adaptive tool-use by determining whether a visual problem truly requires tools.
Outcome: The proposed model outperforms existing methods in visual reasoning tasks.
KEHRL: Learning Knowledge-Enhanced Language Representations with Hierarchical Reinforcement Learning (2024.lrec-main)

Copied to clipboard

Challenge: General pre-trained language models (PLMs) leverage relation triples from knowledge graphs (KGs) and integrate external data sources into language models via self-supervised learning.
Approach: They propose to learn Knowledge-Enhanced language representations with Hierarchical Reinforcement Learning (KEHRL) to detect positions for knowledge injection and integrate external knowledge into the model to avoid injecting inaccurate or irrelevant knowledge.
