Don’t Start Over: A Cost-Effective Framework for Migrating Personalized Prompts Between LLMs

AAAI 2026technical

Personalization in Large Language Models (LLMs) often relies on user-specific soft prompts. However, these prompts become obsolete when the foundation model is upgraded, necessitating costly, full-scale retraining. To overcome this limitation, we propose the Prompt-level User Migration Adapter (PUMA

Document-Level Event Argument Extraction With a Chain Reasoning Paradigm

ACL 2023long

Document-level event argument extraction aims to identify event arguments beyond sentence level, where a significant challenge is to model long-range dependencies. Focusing on this challenge, we present a new chain reasoning paradigm for the task, which can generate decomposable first-order logic ru…

A Simple and Effective Method to Improve Zero-Shot Cross-Lingual Transfer Learning

COLING 2022main

Existing zero-shot cross-lingual transfer methods rely on parallel corpora or bilingual dictionaries, which are expensive and impractical for low-resource languages. To disengage from these dependencies, researchers have explored training multilingual models on English-only resources and transferrin…

Multi-stage Distillation Framework for Cross-Lingual Semantic Similarity Matching

NAACL 2022findings

Previous studies have proved that cross-lingual knowledge distillation can significantly improve the performance of pre-trained models for cross-lingual similarity matching tasks. However, the student model needs to be large in this operation. Otherwise, its performance will drop sharply, thus makin…

Parameter-efficient Continual Learning Framework in Industrial Real-time Text Classification System

NAACL 2022industry

Catastrophic forgetting is a challenge for model deployment in industrial real-time systems, which requires the model to quickly master a new task without forgetting the old one. Continual learning aims to solve this problem; however, it usually updates all the model parameters, resulting in extensi…
