Earley-Driven Dynamic Pruning for Efficient Structured Decoding

Xintong Sun, Chi Wei, Minghao Tian, Shiwen Ni

ICML 2025poster

Large Language Models (LLMs) have shown remarkable capabilities, yet ensuring their outputs conform to strict structural or grammatical constraints remains challenging, which is critical in function calls and domain-specific language (DSL) generation. Constrained decoding with context-free grammar i…

Training a Better Chinese Spelling Correction Model via Prior-knowledge Guided Teacher

Chi Wei, Shaobin Huang, Rongsheng Li, Naiyu Yan, Rui Wang

ACL 2024findings

Recent advancements in Chinese Spelling Correction (CSC) predominantly leverage pre-trained language models (PLMs). However, a notable challenge with fine-tuned PLM-based CSC models is their tendency to over-correct, leading to poor generalization for error patterns outside the standard distribution…
